The screen on most e-readers uses a technology called e-Ink. E-Ink makes it so the screen of an e-reader looks more like a paper book. The screen does not emit light like an LCD computer screen does. If you want to read in the dark you will need some kind of light source to see the pages. One of the main advantages of this technology is that it causes less strain on your eye than an LCD screen. It really shouldn't cause any more strain than reading an actual book.

The second thing you should understand about an e-reader is that an e-reader usually gets it's reading material from a virtual store that is created by the manufacturer of the e-reader. The Kindle, for example, uses The Kindle Store which is run by Amazon. In most cases you are able to download your books wirelessly from the e-book store directly to your e-reader.

An e-reader is capable of storing many books in its memory. Many are capable of literally storing thousands of books. This means that you are able to carry your entire library of books with you at all times. Anytime you want to read any one of your e-books it's available to you. These are the basics to understanding what an e-reader is. Give an e-reader a chance. It might be the perfect solution for you.

Tips To Buy Used Probe Stations

2010-12-25T00:29:00.000-08:00

According to Electronic Engineering Times, a comprehensive resource for industry news, predicted in 2009 that companies are increasingly opting to invest in second-hand semiconductor equipment. Industry pundits feel that this trend is the fallout of the recession-the downturn was a time when companies realized that it was more profitable to acquire second-hand and refurbished semiconductor equipment in working condition and from a trusted source than invest significantly in a new piece of equipment.

A mechanical probe station is usually used to physically receive signals from the nodes that are placed inside any semiconductor equipment. The probe station uses manipulators that ensure the fine needles can be precisely positioned on the semiconductor device. The probe station is also widely used to analysis the failure statistics of semiconductor machinery. The increasing preference for second-hand semiconductor equipment has also meant an increase in the demand for used probe stations and rightly so! Now if you have decided to invest in one, here are some tips to help you spot one that will give you the most return on your investment:

* Settle for a well-known brand. They say "Name sells" and it does, indeed! When choosing to buy used probe stations, go to a supplier who stocks products from well-known brands. You can thus be certain that a particular piece of equipment had been originally assembled using nothing but parts of the best quality and while adhering to the most stringent production processes.

* Ensure that the used probe stations have gone through an extensive and stringent refurbishment process. Even when you are buying a used product, make sure that you receive a product that exactly matches the original factory specifications. If required, demand to know the stages of the refurbishment process from the supplier.

* Compare prices from different suppliers. Financial considerations were primarily what that prompted you to go in for used probe stations. So after you have drawn up a list of suppliers who stock equipment of only the best quality, it is time you compared their prices. Settle for the supplier who has the most competitive prices.

Now wouldn't you rather settle for a supplier who you can trust to stock only the most well-known brands of semiconductor equipment, follows a strict process for refurbishing used probe stations, and offers extremely competitive prices? Then, ClassOne Equipment is the destination for you, as it for countless other companies who value quality above everything else. They are a well-known supplier of used probe stations, used dicing saws, and used wet benches.

The Do's and Don'ts For Avoiding Spyware

2010-11-11T22:58:00.001-08:00

The big buzz words today for anyone who owns a computer and surfs the internet is Spyware and Adware. Spyware is software that installs itself onto your computer without your consent. Once the spyware has been successfully installed, it will monitor your surfing habits for marketing purposes. Some of the more malicious spyware will collect your keystrokes - this will allow them to collect your personal information and credit card numbers. Spyware has become a terrible nuisance and, more importantly, a potential security threat to all PC owners.

It is common for people to confuse "adware" with "spyware". Adware is software that comes bundled with a program that is probably free. This is how the company offering the software can afford to give it away for free. In return for the free program, the user will view some ads. However, some of these adware programs have tracking features, which causes potential dangers.

Do's:

1. Make sure your computer is setup to download and install Windows updates "Automatically". This will ensure your computer is receiving the latest security updates from Microsoft.
2. Install a good, well-known anti-virus program (such as Norton, McAfee, AVG). Set up your anti-virus program to download the latest virus definitions as often as possible and scan your computer on a daily or weekly basis.
3. Beware of some "free" anti-virus programs on the Internet; they may be fake and end up installing the spyware you are looking to avoid.
4. Install a separate anti-spyware program. Several reliable, free programs that you can download are Malwarebytes, Spybot, and SuperAntispyware.
5. Be careful when installing any program on your computer. Many software programs bundle additional programs with them that are installed at the same time.
6. Keep an eye on what your children are doing on the Internet. Monitor what sites they are visiting and the files they are downloading.

Don'ts

1. Avoid downloading anything from an unrecognized source, especially if it is offered for free. If the offer sounds too good to be true, then you may be downloading more than you bargained for. Stick to reputable sites for downloading - such as iTunes for music, etc.
2. Try and stay away from installing Internet Explorer toolbars. They are a known target for unwanted spyware.
3. Don't click on any advertisements while surfing the Internet. If you do receive a pop-up ad, click on the X in the top right hand corner to close it.
4. Don't open attachments or click on links in emails from unknown senders. Best practice - don't open the email at all if you don't know who sent it to you.
5. Stay away from file-sharing websites - they are notorious for spyware.

Ten Tips to Protect Your Personal Information and Identity

2010-11-11T22:57:00.002-08:00

Every time you go onto the Internet and surf, there are numerous threats and dangers against your personal information and identity. From emailing to online shopping to Instant Messaging, all of these behaviors will leave you vulnerable unless you take the correct precautions.

Below are 10 tips to help keep your personal information and identity safe.

1. Only use computers that you know are secure. While you may know your own personal computer is secure, remember if you borrow a friend's computer for convenience one day, they might not have the same security precautions put in place.
2. Install and use a good, reputable anti-virus program. Ensure that it is downloading the latest virus definitions and is scanning your computer at least weekly.
3. Take care when registering to websites. Use a strong password (one that contains capitals, numbers or special characters) and don't use the same user name and password for all of your sites.
4. Always use protected Wi-Fi connections. While places like Starbucks offer free Wi-Fi, it's on an unsafe public network. The easiest way to protect yourself is to connect only to secure networks: they usually have a lock symbol next to them, and may mention WPA or WEP encryption. Make certain as well that your own Wi-Fi network is also secured.
5. Be careful when you email. Watch out for phishing scams - this is where hackers sent fake emails that look real asking for your personal information. They might be disguised as your financial institution. Never click on any links inside any suspicious emails.
6. Never type personal information while Instant Messaging. This form of communication is a big target for hackers. Take some security measures in your IM application, such as turning off logging, so a record is not kept of your conversations. You can also purchase some very easy to use encryption programs that will encrypt your communications. Skype has encryption built in and is a simple solution.
7. Do not install unwanted programs. Many applications will bundle additional software in with their program. When installing software, be aware of any other program names that are selected to be installed and uncheck them.
8. Monitor your credit reports on a regular basis. At least once a year, check your credit history and review for any suspicious entries or inquiries on your credit.
9. Keep an eye on what your children are doing online as well. Install and use parental control software or a service through your Internet Provider to help monitor and block their Internet surfing.
10. Always keep a good backup of your data. You can copy your files, pictures, or music to external hard drive so you can restore this data in case of any emergency.

How to Protect Your Children on the Internet

2010-11-11T22:57:00.001-08:00

The Internet can be a great resource for children for both learning and play. They can use it for school projects and book reports (instead of having to hike to the library like we did), keeping in touch with their friends and playing interactive games.

However, as we all know, the Internet is filled with hidden dangers. An innocent search of the word "Legos" can be misspelled to "Legs" and your child may be directed to some sites that are inappropriate for children of any age.

This is why it is so important to be aware of what your children are doing online, who they are chatting with and what sites they are visiting. Even with laws such as Children's Online Privacy Protection Act (COPPA), your child's best online protection is you. Talk to them about the dangers and monitor their online usage to help them surf the Internet safely.

Here are some great tips to keep your children safe while still allowing them to explore the wonderful world of the Internet.

1. Keep the computer in a common area, such as the family room or dining room, so you can more closely monitor your children's activities.
2. Let your young children know that chat rooms are off limits. You can use special software or contact your Internet provider to block these sites. If your child is a teenager, and you do allow them to access chat rooms, monitor this and your teenager's behavior closely.
3. Bookmark your children's favorite sites so they will be less likely to have to go to search engine sites to search for what they want.
4. Talk to the parents of your children's friends and their teachers - find out what online protection is being offered when they are away from home.
5. Investigate the many types of software out there that will allow you to customize what you want to allow your children to access and what you would like to block them from seeing. Your Internet provider may also have options to help you control Internet usage.
6. Caution your children to never reveal any personal information online, like their name, address, phone number or even send pictures to people they do not know. In addition, they should never respond to any emails from people that they do not know and should let you know about anything that happens that makes them feel uncomfortable.

Taking a pro-active and serious role in your children's Internet activities will help ensure that they benefit from the valuable information it offers without being exposed to any potential dangers.

Why Waste Your Time With a Lessons Learned Process?

2010-06-26T01:42:00.006-07:00

Admittedly, lessons learned (often dubbed the project's "post- mortem analysis") is a task that comes after project launch and certainly isn't given as much attention. Most project managers fail to do it at all and get along just fine doing so. So why the focus on it now?

Documenting lessons learned is an integral part of the life cycle management of a project and is especially helpful to project managers who want to get better at their job over time. Just think of the repetitive nature of their role: project managers end up performing the same sort of tasks in each project, whether it be building a team, communicating with and managing stakeholders, or hiring third-party vendors. With all of these tasks, understanding how they succeeded and where they failed will maximize their performance over time and ultimately improve the efficiency with which they manage our assignments.

In my current role as a technical project manager, I've led 30+ engagements, some big and some small, and have worked with many of the same stakeholder groups in each one. It is very useful for me to receive feedback from clients and stakeholders after each project has ended, specifically on topics like the following:

What was the single most frustrating part of our project?
Was communication on project progress informative and timely?
Did we have the right people assigned to the right roles?
Do you think we could have completed this project well without one or more of our vendors?

Building this repository of feedback helps me focus on areas for improvement and contributes to a winning relationship with my clients. And trust me--having that relationship and staying in tune to the needs of my stakeholders makes what could be very difficult project tasks that much easier! But why else should a lessons learned process be instituted? There is already a vast body of knowledge available to managers online and in books authored by seasoned PMPs that you can rely on to navigate through the pitfalls and tests of a project.

Using the lessons learned process to build your own personal resource with a history of what worked and what didn't in your projects builds on the already helpful resources.

Don't hesitate to share these gems with PMs in your own organizations to improve their skills. This process also proves even more useful because you actually experienced the victories and challenges yourself. Experience is the best teacher; take advantage of yours and the experiences of others.

Pros and Cons of Spaghetti Integration & Star Integration

2010-06-26T01:42:00.005-07:00

A few years ago, IKEA released a VERY hilarious commercial to promote its simple and clean furniture line to organize a home or office space. In short, the commercial opened with an attractive couple, in a rather unattractive and untidy room, sharing a single spaghetti dinner. They savored and slurped each noodle as suggestively as a bowl of pasta can possibly be eaten. The female -- with eyes closed, head to plate, mesmerizing her partner with her technique -- was so engrossed in her sensual display that she accidentally mistook as another noodle her boyfriend's filthy shoelaces which, of course, were tied to his even filthier sneakers. (If this is too gross for you, that may help to explain why it was banned in the US.) The commercial faded out and ended with a silent, but poignant reminder: "Tidy Up".

Just like with an untidy room, a spaghetti integration (or star integration) may take months, even years, to get to the point of being disorderly. Traditionally, each department in an organization may use independent systems to meet their own needs so that they are autonomous and easier to manage internally. Then, as new requirements arise, as an organization grows, and as inter-departmental communication becomes more important, point-to-point interfaces develop to tie each autonomous system together - hence, a badly-planned "spaghetti" of systems arises.

So, what's wrong with that, you say? Here are my top 3 cons:

1. Just as a cluttered room is a sign of a cluttered mind, a disorganized system is a sign of a disjointed IT management team. Taking the most expedient, quick-and-dirty, route to integration is a sign of little collective system management efforts. This lack of foresight leads to complications and problems in the long run... see #2.

2. Making changes to a single application or database in a star integration can be costly. Sure, it's easier to make quick changes in a single system, giving the organization the appearance of agility. But, when those changes lead to a collection of functionality that is characteristically not reusable and buggy, the cost of maintaining that new functionality will rise exponentially as your system grows.

3. Business Intelligence suffers as company data that lives in multiple places in a spaghetti integration is more difficult to consolidate into a single and useful data-mart. This makes it harder to paint a clear picture, whether it be analytical or operational, of the organization as a whole, and to keep from being reactionary and inflexible in the long run. But spaghetti integration isn't all bad. New application features can be implemented quickly, and because system component structure is not as rigid, there is an advantage of flexibility in deployment.

What is Cloud Computing and How it Can Help Your Business?

2010-06-26T01:42:00.003-07:00

Despite the enormous interest to the concept of "cloud computing", there are no accepted standards and methods of maintenance of the guaranteed quality of service. The phenomenon of calculations in cloud computing causes a great interest all over the world: the new concept allows giving services on demand thus decreasing the expenses. Besides, such approach allows to lower complexity of information systems, and also to increase their scalability and availability. The new model gives to suppliers of managed services wide and fascinating possibilities.

Since network ARPANET has formed a basis for the popular Internet, a set of network concepts was developed for corporate customers and individual users. According to the concept of cloud service, network and computing resources should be given to each person on demand, like electricity for example. In this sense some analysts began to speak about network transformation into the fourth municipal service in addition to water, electricity and telecommunication.

Such companies as Google and Amazon, already offer today services (Google App Engine and Amazon Elastic Compute Cloud 2 and Elastic Block Store). Behind these services there are data processing centers, providing the creation of the necessary infrastructure and supporting key technologies and sharing of resources (multi-tenancy) which make the system of cloud computing more effective and economic both for operators and for users.

Cloud service draws the attention of experts because it may become a new revolutionary technology which will reverse business models of the communication industry. The research done by Gartner Company in 2008, has shown that the technology of cloud computing will be useful for both large and mid-size communication companies. The economy will lead to depreciation of services of cloud computing at the expense of simplicity of scaling.

Companies that solve the big computing problems can receive results much faster and more economically if they involve wide resources of suppliers of cloud computing.

Cloud Computing - Pay For Usage, Not Availability!

2010-06-26T01:42:00.001-07:00

Certainly, we have progressed immensely in the world of technology and specifically in the world of computers. Not so long ago, computers were gigantic mainframe pieces that were only affordable to the rich, to large corporations, or to governments. We then watched as the computer shrank in size and then personal computers were originated. As we have watched the explosion of the internet and various internet-related companies and technologies, we have progresses to the point where we can actually simplify some computing needs. What do I mean? I am referring to the world of cloud computing.

In a traditional home computer or private business computing environment, whatever technology you needed, you simply had to purchase. So did everyone else who was in the "same boat." Many companies made a whole lot of money based upon this premise--one couldn't "share" technology amongst themselves, everyone needed to pay for their own version of what they desired. Suddenly, in the last few years, we are moving away from that model as production costs for technology are decreasing and we actually are moving toward a simpler concept of computing needs--pay for what you use, not for the ability to have it if you need to use it.

Of course, like any new concept or idea--each entity must investigate this notion for themselves. Cloud computing works similarly to electricity or water rates--you pay for the amount that you use and you are not bound contractually for any length of time and you are not responsible for footing the bill for individual technology that someone else isn't funding or opting to fund. The technology is housed in a third-party provider--thus, you can access the business applications you need and require but only at the usage that is specifically what you need and require. This can save a lot of monies in capital investments and fixed costs.

Of course, if you are in an industry where capital and fixed costs are not that great, then this strategy could actually cost one monies. Therefore, it is important to do a cost-benefit analysis on the merits of this system before readily jumping into it. However, for the majority of businesses and individuals, this can be quite a "godsend." One doesn't have to outlay a whole lot of monies to get started and again--you simply pay for what you use. Technology has developed a great deal, ironically to the point where it is now starting to employ simpler concepts. What works for your needs?

Data Center Management and It's Importance

2010-06-26T01:41:00.000-07:00

Data center management isn't something to joke around about nowadays. After the plethora of disasters we've seen in the last few years, being able to safely manage our data has become of the utmost importance.

When a storm or electric failure hits, you need to be able to recall the files necessary to sustain your business. This can take weeks if not properly stored, and then you still might lose a bit of your data.

Lately, more and more companies have looked into better methods of data center management. Some of these methods are as simple as creating a hard copy. Others actually store your information online just in case something happens and you need to get a hold of it.

In a few ways, the online backup idea is a bit better than your standard old hard copy. With a hard copy of your data, it can be broken or misplaced, which isn't acceptable during an emergency. Despite how large the internet is, it is not capable of losing your data as you would in real life.

Online data center management is also somewhat helpful to the environment, as opposed to hard copies. It doesn't take up nearly as much space, especially with the increased memory a computer can hold. With the expansion of the memory a computer is able to store, it has also become easier to manage data and still keep up with the business's needs.

However, not having enough power capacity also hinders the management of data due to the inability to support all the data needed. It is best to simply store what you absolutely need the most and wait until a later date or to not store the rest of the data. If you choose just the essentials for keeping your business, you should be just fine.

The data also must be regulated to make sure that every time important data is acquired that it is uploaded and stored as soon as possible so that it is not lost during the next disaster. Trivial issues aside, data center management is extremely fundamental to the growth of current and up and coming companies.

History of Computers - Briefly Put

2010-03-01T04:34:00.003-08:00

The need to carry out complex calculations has culminated the computer from its mechanical roots of relays and movable parts. While calculating devices have been around since around 3000 BC, modern computing technology traces its roots to 16-17th Centuries. The Evolution of computers is often categorized in Generations. It is relevant to note a period before these a "generation 0" between 1640s-1940s whose machines were mechanical devices (e.g. relays and gears) including Pascal's Pascaline, the first mechanical calculator.

Generations of Computers

First Generation (1945-1959) Vacuum Tubes

Relays were replaced by vacuum tubes which had no moving parts hence faster, eventually hybrids of both were built. The first electronic computers were the COLOSSUS (1943 - though not publicly-acknowledged) and ENIAC (1946) which contained 18000 vacuum tubes and 1500 relays. Also notable was UNIVAC which became the first commercially available computer.

Second Generation (1960-1965) Transistors

Vacuum tubes replaced by transistors (Invented at Bell Labs in 1948). High Level programming languages developed; FORTRAN and COBOL among others. Transistors were much smaller, and cheaper to make and far more reliable than valves.

Third Generation (1965-1971) Integrated Circuits

Machine speeds went from microsecond to the picoseconds (trillionth) range. Terminals replaced punched cards for data entry. This era saw the rise of Operating Systems and mass production of circuitry. IBM introduced compatible family of computers

Fourth Generation (1973-) VLSI - Very Large Scale Integration

Allowed thousands of transistors to be incorporated in a chip giving rise to the microprocessor- a processor on a chip. These reduced the price of computers giving rise personal computing.

The 1990s saw the Fourth Generation advance into ULSI (Ultra Large Scale Integration) with millions of transistors per chip. In 1965 Intel's Gordon Moore predicted "the number of transistors on an IC wills double every 18 months."

Fifth Generation (1985- ) Parallel Processing and Networking

Still a debated generation. How high end machines (e.g. web servers) can have multiple CPUs and inter-connectivity between computers; networks.

Where Can I Get Free Proxy Servers?

2010-03-01T04:34:00.001-08:00

For those people who are always trying to preserve and protect their privacy can always turn to the internet for a fast and free fix. This is where they can get a piece of the action for free. They use free proxies on the net but may risk something more.

Using free proxy is not without risks. There are over a thousand proxy servers that seem to be ready for use since their administrators have been mis-configured their servers and are unaware that their servers have been tainted or contaminated by outside influence. This is the danger of free proxies. They are on the net and for free but may have been influenced by other sources.

Not all the free servers are there to protect you. On the contrary, some of these free proxy are designed to steal information from a casual user. In cases where legit servers have been hacked, they are used to pry into other member's accounts and let the information be accessed.

Some experts cite that why would a proxy server be let for free when it actually costs a lot more money to protect one person? Who is the person that can afford to subsidize over a million proxy users?

Somehow it doesn't make sense.

So where can you get a free proxy server that really works? The answer is you can't rely on a 100 percent reliable one. Chances are that somewhere along the line your identity gets compromised and you are left exposed. Using a free proxy server means using a poorly designed one. It may process your request at a high speed but in reality, proxy servers are really slow since there are safeguards that whole sites have to go through. When you think how a lot of people do this you begin to wonder if it really does work or is it just hype.

If you want to risk yourself by using free server proxies, go ahead but there are actually ways that are not so expensive to protect yourself and your privacy. You can opt to use paid encryption services that are really hard to beat but they can only be used on specific tasks like email correspondence. Some legit services do offer anonymity but at a price. It all depends if you want to pay for it.

You should decide whether your need for using a free proxy server is for fun or for serious work. If it is for serious work then you should not leave things to chance. So where can you go to get free proxy servers? The internet but you risk exposing yourself to fraud and theft.

A Guide on How to Use a Laminating Machine

2010-03-01T04:33:00.002-08:00

Protecting documents by the use of a laminating machine is actually easy once you get a hang of it. Whether you are using a pouch laminator, roll laminator or even self seal sheets, with a little practice you will soon see that the process is not that difficult at all.

First off, pouch laminating machines are the most common laminators around. To start the laminating process, you must turn on the machine and have it warm up for a few minutes. A typical warm up process can take up to 10 minutes, depending on what brand or model of pouch laminator you are using. You must also set the heat settings. You must determine how much heat must be applied to bind the pouches. For thick documents, a higher setting is ideal.

When you have achieved the desired heat level, you can now place the documents that you want to bind inside the pouch. The pouch will then be inserted into the machine with the closed edges first. This is done to prevent air bubbles from forming during the laminating process. Another option is to use a carrier. Some machines use this to prevent excess glue from dripping into the rollers and minimize the formation of bubbles.

Roll laminators on the other hand requires a different approach. The process of setting up the machine will be different although, the principles on how to laminate a document is the same. For starters, check if the heat shield and feed tray are in place. If they are not placed correctly, the machine will not move.

Like pouch laminators, you must determine the heat setting and then warm up the machine. When everything is ready, you can now place the document into the feed table and press run. The machine will now roll in the document and laminate it. If you have various documents that need to be laminated, then you can place one after the other. The finished product then exits in the back of the machine.

Pretty much like all machines, learning to use a laminator takes some patience and experimentation. If you can devote some time, then you are guaranteed laminate your documents like a pro.

The Best Way to Clean a DVD Player

2010-03-01T04:33:00.001-08:00

We use a DVD for several applications. We can watch a movie in it or play your favorite video games. The DVDs may not function well if it becomes dirty. It has a tendency to skip when it becomes too dirty. It will also have a hard time reading the information properly. The dirt becomes a hindrance for reading the data. Cleaning the DVD is not so hard as long as you follow the right steps accordingly. This is moderately difficult task. The things you will need are duster, cleaning disc, alcohol, q-tips, screw driver and three in one oil.

1. The first step on how to clean a DVD is unplugging it properly. You should make sure that it's completely connected. You should then put it in another place where you would get a lot of room for cleaning it.

2. The second step on how to clean a DVD is examining the player. Check the vents and the fans. You must check if there is a thick build up of the dirt or grime. If the area with the vents already has a big accumulation then it means that you have not cleaned it for a very long time. It would not help if you use the duster on it because it will just get blown back to the player. If the accumulated dust is just light then you should start cleaning it by just blowing on it. There are some DVD players that let you open it up so you can blow on it easily.

3. The third step on how to clean a DVD is putting the disc for cleaning it. You can just watch as it does its job. For a large accumulation of dust or dirt it may not play properly. However if the disc for cleaning finished until the end then you can end your cleaning process

4. The fourth step on how to clean a DVD is disassembling the DVD. This will enable you to clean and remove the large build up of dirt properly. You should start this by looking for the player's seams, security tape and screws. Be careful of the tape because if that breaks then you will not be able to avail your warranty in case it breaks down. You can risk this and open the player. You do this by first removing the screws which you will find on the player's bottom. You should just be taking the casing out then remove the dust accumulation on the vents first by using your duster. Be careful not to shake it because the nitrogen might leak out and damage the player.

5. The fifth step on how to clean a DVD is putting alcohol on your q-tips. Then swipe it on the part with the laser. You can then rub it on the rails if you find any dust on it. Do not swipe the alcohol on the circuits.

6. The sixth step on how to clean a DVD is letting it dry properly. You start by dipping a q-tip with the oil and brushing it on the rails. Then after a few minutes of drying you can close it now and then play the disc for cleaning the player. Then if it plays all the way to the end then you have successfully cleaned your DVD.

Understanding HTTP Proxies

2010-03-01T04:32:00.000-08:00

Ever wonder how we get all those spam emails selling us stuff; saying that we have been pre-approved for a certain credit card; or offering us many different things from playing online casino to subscribing to pay-per-view shows and such?

There are a lot of reasons why we get all these kinds of emails; one of which is that our email address has been sold to a third-party buyer when we signed-up for certain online promos.

Another bigger reason is that our browsing habits have been monitored and tracked down by other websites who use trackers specifically for the purpose of marketing.

How do they track us down? They do this by using our Internet Protocol addresses. This is where an HTTP Proxy can come into play. What are these?

IP ADDRESSES AND HTTP PROXIES

IP ADDRESS

To know the answer to What are HTTP Proxies?; we must first understand what an IP Address is. Simply put, an IP Address is the configuration that the computer network has designated to our computers.

The IP Address allows other computers to connect to us when we are online to give us information on things we are looking for or to hook us up to the websites that we want to browse.

With this unique number configuration, it will be easy for internet predators to track down our browsing habits; from the sites that we frequent to our location. But these are not all that our IP Address can reveal about us.

Identity thefts; credit card fraud and other online malicious activities may befall us all because of our IP Address.

HTTP PROXIES

Now these are alternative servers that we can use when surfing the internet to allow our own IP Address to be hidden from online predators.

These will send information to the World Wide Web through an anonymous proxy server so that our online computer identity will not be open to the internet network.

To further understand What are HTTP Proxies?; what happens when we use them is that when we send information to the internet using any one of these HTTP Proxies; they use their own IP Address instead of ours.

We may think that this is already the solution we are looking for to prevent malicious hackers from using our identities but there's more to What are HTTP Proxies? than just hiding our identities.

There are open HTTP Proxies that can do more damage to us than our own IP Addresses. These types of proxy servers are often manipulated by again, malicious users to control our computers to hack into or attack other computers; using us as the end-user.

The more reliable proxy servers are what we call Web-based HTTP Proxies. These do not require downloads or configuring our browsers; and these operate solely through Web browsers.

Now that we know a few things about the question What are HTTP Proxies?; it is solely upon our own discretion whether we want to use these or not. We should first weigh the pros and cons of using these proxy servers before using them.

Bluetooth Wireless Device Not Found in Windows XP Service Pack 2 - How to Fix It

2010-02-02T06:22:00.001-08:00

When installing your Bluetooth enabled-device in Windows XP Service Pack 2, sometimes you will find this device can not be correctly recognized in Device Manager; if you try to use it, you will see some error massages like "Device not found" on the screen.

Commonly there are two cases that would cause this error: one is that the Bluetooth device has already been installed in your computer before you install Windows XP Service Pack 2, and you haven't installed the third party Bluetooth driver; two, Windows has automatically installed its built-in driver rather than install the third party driver.

Finding out and install the right third party Bluetooth driver may be a very complicated and time-wasting job, for there are hundreds of thousands of drivers for you to choose on the Internet, furthermore the Bluetooth driver used on one type of computer may not work on another because of differences in hardware specifications and operating systems. So you need a good driver tool to simplify your driver search and updates. Among numerous driver programs, Driver Checker is your right choice; with several clicks, Driver Checker will automatically search the Internet and manufacturer's websites for updated drivers that are specific to your Bluetooth device, operating system and compatible with your PC's hardware components so as to make the most out of the dongle.

And to resolve your Bluetooth device problem you can follow the methods below:

Method 1

Rename the bth.inf file: before setting up the third party driver, rename %WINDIR%\inf\bth.inf file as bth.bak, so as to prevent Windows Plug-and-Play using this INF file to set up Windows built-in driver.

Tips to rename this file:

Step 1 Click Start, choose Run, input %windir%\inf in the box and then click OK.

Step 2 Right click bth.inf and choose Rename, after that rename it as bth.bak.

Step 3 Download Driver Checker to install the best driver for your Bluetooth adapter.

Method 2

Replace Windows driver by specifying the third party driver for your Bluetooth device in Device Manager.

Step 1 Set up the third party Bluetooth driver and remember its location in your computer.

Step 2 Click Start, choose Run, input devmgmt.msc and click OK to open the Device Manager.

Step 3 Expand Bluetooth Devices and find out this device.

Step 4 Right click it and then select Update Driver

Step 5 In the update wizard, select Install from a list or specific location (Advanced) and click Next.

Step 6 Choose Search for the best driver in these locations and Include this location in the search.

Step 7 Click Browse to find out the address of your third party driver and then click Next to finish this installation.

Method 3

Use Driver Checker's automatic uninstall and install features to help you unload the inappropriate driver and install the compatible and latest driver quickly just with a few clicks.

Script Resource Websites and Their Importance

2010-02-02T06:21:00.004-08:00

With the conversion of Internet from a basic source of information to a major variable in businesses across the world, software scripts have taken a major role. In fact, the application of software scripts has multiplied at such a rate that companies that are not even linked to the IT sector have started keeping an in-house or consultant software script programmer. Companies require these scripts for various types of software like messengers, backend maintenance, website supporting software, or even internal network maintenance software. However, having an in-house or consultant software script programmer becomes very difficult for small to medium companies as it results in a lot of expenditure. Hence, many companies that cannot afford to keep an in-house or consultant software script programmer have started resorting to script resource websites.

As per recent trends, various small scale companies to medium scale companies have started using the services of these types of websites. The primary reason for such an en masse switch toward the utilization of these websites is that it allows these companies to save a lot of money. This financial efficiency allows the company to put in more money into its other operations and hence improve its total performance. As any statistician will agree, the number of small scale to medium scale companies is much higher than companies who can afford to have an in-house or consultant software script programmer. This ends up inducing a kind of proliferation for script resource websites in the cyberspace.

These websites provides scripts for dating software, audio and video messengers, shopping carts, and media publishing software among many others. As is apparent, most of these software would be extremely beneficial for Internet, Intranet, or communication based companies. Therefore, the kind of clientele that these websites enjoy include online shopping websites, blogging websites, networking websites, dating websites, and many other associated websites. In addition, these websites also take on special projects entailing script designing for highly specific software that a client may want. Furthermore, there are even certain websites that offer basic scripts for simple software for free. There are many online entrepreneurs in the market these days with new and innovative ideas but without appropriate capital to make their concepts work properly. Script resource websites are the ideal solution providers for these kinds of business ventures.

Although, the growth of these websites is directly linked to the growth of Internet and its applications, they should also be given credit for fueling the growth of cyberspace. This is because these kinds of websites make it easier for a budding entrepreneur with new ideas to implement his or her ideas which, in turn, hold the potential to encourage other entrepreneurs. Therefore, this situation, here, is highly symbiotic with Internet's expansion supporting the growth of script resource websites and vice versa. Consequently, in order to keep the growth of Internet constant, the growth of these websites also takes on more significance.

The Computer Case - The Central Part of a Computer

2010-02-02T06:21:00.003-08:00

Computers have various components, and the computer case is what holds them all together. These cases have changed over the years but remain the central part of any PC. By understanding the cases and how they integrate with the other components, one can better understand computers.

Computers have a number of major parts. The computer case is what houses all the internal components of a computer. Within the case, the motherboard is the single largest component. Attached to it are the CPU (a microprocessor) and the memory (RAM). Ethernet capabilities (for internet connectivity) are usually integrated directly into the motherboard. Other major components inside the case include the optic drives (such as DVD), hard drives for data storage and the power unit.

To connect the computer to peripheral devices, the sound card, video card and cards for USB and other connecting ports all attach to the motherboard. Typically, these peripherals are the monitor, printer, keyboard, mouse and any other devices that need to be connected to a PC.

The optical drives are located in the front of the computer case along with the additional USB ports for easy accessibility. The other peripherals of the computer usually connect through the back of the case.

This case is the largest part of the computer and is typically constructed mainly out of a steel or aluminum. Plastic and acrylics are also used, but their purpose is usually just to enhance the design or look of the case. Much of the weight of the computer (apart from the monitor) is in the case so one should consider its weight and avoid those with sharp, dangerous edges when purchasing. Edges that are beveled or finished are much safer.

Other materials also used to construct computer cases include plastic, Plexiglas, wood and, believe it or not, even Lego blocks! Computer cases have also been referred to as the computer chassis, cabinets, boxes, enclosures, towers or simply just the CPU cases.

When the PC first came onto the scene, the case was horizontal with the monitor being placed on top of it. This design of the case had the power switch behind it with all the ports also placed behind the case. This was a pretty awkward (some would say incomprehensible) position because the operator had to get up and reach all the way behind the computer to switch it on.

When the vertical computer case came on the scene, the monitor could be placed on the desktop with the vertical case (also called the "tower stand") below beside the desk. This was more convenient because it left more space on the desk while allowing the user to access the switches from the front panel.

Some computer cases have been growing smaller in recent years, but there is currently a limit as to how small they can get. While smaller cases are more compact, they often do not have enough space to allow proper cooling or for new devices to be added to the computer. Due to these factors, computer tower stands remain popular.

DVR Card - Record Your Favorite Shows

2010-02-02T06:21:00.001-08:00

A DVR card is used in DVR equipment to store information and to help the equipment function. DVR stands for digital video recorder. A DVR has a host of functions for controlling digital media. Live TV can be paused; events, programs and movies can be recorded. There are playback features and a host of other up to the minute features available with a DVR.

Satellite and DVR

The satellite industry introduced its first DVR back in the nineteen nineties; they took off like rockets everywhere. Everyone wanted one and everyone got one. The DVR can record programs and movies directly from the satellite system; it requires the card that is validated by the satellite system before sending the signal through the DVR box. The card is used a security feature to make sure no one is getting anything for free. It is a computer coded card that can be read by the satellite system. The card holds account information, viewing preferences and a host of other information regarding the customer of the satellite company.

Cable and DVR

Cable companies soon followed the satellite companies in offering DVR boxes with their services. The cable boxes that have DVR capabilities also use a card to share information and to make sure the service is being paid for. Without the card in place and being legitimate the cable will not feed a picture through to the TV set.

Where Does a Card Come From?

It is usually part of the satellite install or the cable install. It is placed in a specific spot on the DVR box and information is immediately uploaded to the server from the card, this information will tell the satellite or the cable company's server exactly what programming packages were picked and other pertinent information. Every once and a while the card will have to be replaced either as part of normal maintenance activities or because there has been some system upgrades requiring the card to be changed. If the card has to be changed out as part of a normal system upgrade or as part of periodic maintenance than the cable or satellite company will send a new card with instructions on how to change it out. If the card picks up a virus or somehow stops suddenly working, than a call to the cable or satellite company is warranted and they will send out a new one. There will be no service until the new one is installed.

Hot Wallpapers of Celebrity Models, Actors and Actresses - An Instant Inspiration!

2010-01-10T10:20:00.003-08:00

Hot wallpapers of celebrity models, actors and actresses are an instant inspiration for me when I am buckled under the pressure of tight schedules. Being in to the consultancy profession, and with a growing list of quality clientele, I am always as busy as a bee. Inevitably, this leaves me often in an emotional vacuum or rather restless nervousness. Luckily for me, I am a fan to a few celebrities in the show business. These include a few film personalities and a string of models. I have habituated to keep wallpapers depicting one or other of these hot celebrities.

Thus, whether before my computer, or making a call or just listening to a tune in my iPhone, these celebrity images excite me, or rather inspire me and enable me to shed my boredom. In fact, if they are film personalities, their figures would invoke in me some unforgettable scenes from some classic renderings on the silver screen. Instantly I may tune on to some sweet melody from those films that I can pick from the stock that I keep with my device. It is a sort of instant inspiration and that is ready at hand.

Amongst hot wallpapers of Hollywood celebrities, the ones of Angelina Jolie is an instant source of inspiration for me. She is endowed with a rare radiance of matchless glory and the reminiscences of the scenes that she immortalized often leave me in moments of ebullient ecstasies of maddening joy. Angelina with her big juicy lips, bad ass attitude and sexy body makes her one of the most favorite celebrities for many and her hot wallpapers are ever chosen with much enthusiasm. Other Hollywood celebrities whose hot wallpapers preferred by many include Scarlett Johansson, Jennifer Lopez or J-Lo, Jessica Alba, Keira Knightley, Carmen Electra, Pamela Anderson and Lindsay Lohan.

Among men, the most preferred wallpapers of Hollywood celebrities include those of Brad Pitt, Johnny Depp, Tom Cruise, Hugh Jackman, Matt Demon, Orlando Bloom, George Clooney, etc.

Well, hot wallpapers of celebrity models, actors and actresses could be an instant inspiration for many during moody moments. As modern psychological findings reveal, the level of excellence in human endeavour could well be fluctuating depending on the psychic ambience in which the purported activity takes place. That is, when you are in psychological doldrums, the level of excellence in the quality of your work could be law. On the other hand, if you are excited, you mind might enfold uncharted realms of imagination and that in turn could churn out superb thought and work.

The Not So Mystery of Duplication Versus Replication

2010-01-10T10:20:00.001-08:00

It has been a long held belief (misunderstanding) among most people that duplication and replication are the same thing. After all, to replicate and to duplicate are just a sophisticated way of saying "to copy" right? Well, technically replication and duplication do mean "copy", but the words are not interchangeable. Both duplication and replication are processes that copy a master disc, but each process uses different methods and has their own advantages. We believe it helps to be informed of the difference between the two so that you will know which process better fits your production needs.

Duplication
CD/DVD duplication involves taking pre-made CD or DVD recordable discs, such as a CD-R or DVD-R, and records them using a write laser. This laser "burns" information directly onto the disc at speeds depending on the drive they are inserted into. After a couple minutes depending on size of information being copied and the speed of the drive, the discs are finished. When they are removed, they are identical copies of the master disc.

Duplication is great when you have low volume quantities, 5000 or less, or you are on a short time table and need discs within 5 days. Duplication also offers full color digital printing for those high quality prints.

Replication
The replication process is different than the duplication process in several ways.

Unlike duplication, replication does not require blank CD or DVD discs, but instead discs are created at the manufacturer with your information on them, or in other words, made from scratch. In order to do this, replication first requires that a glass master disc copy be made. Next, the glass master is used to create what is called a stamper, and it is this stamper that will help create the actual discs. The stamper is then placed inside in an injection-molding machine and plastic is injected to create a perfect copy.

Replications is the best choice for when you have high volume, 1000 discs or more, and have some time to spare. Replicated discs are printed using silkscreen or offset printing methods and most replication manufactures can auto assemble discs into CD jewel cases, paper sleeves, DVD cases, and cardboard sleeves, but other CD/DVD packaging choices are also available.

When you need professional CD, DVD, and Blu-ray duplication services, you can count on the experts at CDROM2GO to get the job done! We take care of everything from duplication and replication to printing, packaging, and even mail fulfillment!

In an era when time ticks faster than ever, speed and information at the touch of a button is a necessity. The current mode of health-information storage is an EMR[Electronic Medical Record] which is a computerized data repository created in an organization that delivers health care, such as a hospital or clinic. EMR allows storage, retrieval and manipulation of records. Of the one-quarter office-based physicians in the United States who use EMR, only less than 10% have a complete EMR system that includes all 4 basic functions; ie, computerized orders for prescriptions, computerized orders for tests, reporting of test results, and physician notes.

EHR and all about it:

The dawn of a new-era is here. With the advent of EHR [Electronic Health Record], the accuracy of transcribed reports are going to reach new levels. EHR has an advantage over EMR, as in being an aggregate of electronic records of health-information accumulated over time; the information being able to be transferred and accessed within the health care organization. These records would provide all the relevant medical history, medication and allergies, immunization status, laboratory test results, radiology images and billing status information of an individual or population, which would in turn enhance patient - treatment and care. Not to mention avoiding the hassle of safe-keeping papers and reports, ensuring easy storage and retrieval of health records at any given time. An added advantage is that, information can be shared and updated among attending practitioners and health organizations with ease. EHR is bound to become one of the means of taking medical transcription services to new heights.

Legal Safety:

Data safety of these health records are protected by the data protection legislation. Based on laws and ethics, an EHR is generated and maintained only by the creator and custodian of the record, such as a health care practice or facility. The physical medical records remain as the property of the medical provider and cannot be tampered with in anyway. However, according to HIPAA [Health Insurance Portability and Accountability Act], the patient owns the information and content of the records, and is legally allowed to view the originals and obtain copies of the same.

How soon?

It has been officially declared that all doctors and other health care practitioners have to use CCHIT [Certification Commission for Health Information Technology] certified EHR by the year 2011. Those who do not comply will be penalized and those who switch at the earliest will be recognized with incentives, etc. The latest statistics regarding the adoption and use of Electronic Health Records are based on the government-sponsored survey report published by the New England Journal of Medicine. It reports that only 9% of medical practices with less than 3 physicians have switched to EHR. On the other hand, practices with 50 or more physicians have shown a 50% EHR-usage. Medical Transcription Companies will be able to provide fuller, more detailed and organized longitudinal reports of patients, which can remain as long-term documents that can be produced and referred to whenever the need arises.

Some Important Guidelines to Select an IT Support Supplier

2010-01-10T10:16:00.000-08:00

You need to ensure that you look for a firm that is of best interest to you as well as your business. For this you also have to carry on some research and verify different firms prior to determining which is the best and ideal solution for you or your company. You can even work out with a person having years of experience and mastery in delivering cut to cut solutions from any problems in the field of IT. At the same time, remember that you have to keep yourself aware or alert from people who make an effort to sell sometime to you that is out dated already.

After narrowing your preferences, sit down along with a representative member from different firms. You will have to ask various questions regarding their technology knowledge, qualifications, experience, etc and so on. Ensure that the individual is able to understand what your requirements are. They should be capable of answering your questions regarding data technology solutions that you are interested to use for your business currency as well as in the coming future.

You may also go in for looking for a business partner who can ask questions and verifies your current model of business and its structure. You may hire someone who would be providing solutions that are particularly directed towards your business and not only keep on offering only generic solutions that are not applicable to your business in any mode. A well known and a prosperous firm would have well established associations with key providers like Cisco, Citrix and Microsoft.

Ensure that you discover their policies of support and services. Also ensure that you can interact with a knowledgeable individual. Make it crystal clear at the beginning only that you wish to contact data for a person who can offer instant help and support. There is no need to go through different people and keep on waiting for their replies. You just need an assurance that whatever your issue is, it would be solved and taken care of instantly without the need to wait for days together.

One also needs to be assured as to the one who would be executing your IT solution services are qualified ones. You need to confirm their experience as well as technical qualifications in executing cut to cut solutions. You need a person who can customize the ideas in order to meet all the particular needs of your existing business.

It is also important to look into the expense of the system as to the consulting charges, etc. Be on the lookout for offensive consulting charges. You should be aware of precisely what you are receiving and what are you paying for. Never get tied up in an agreement where without any need you do pay for a number of experts who are not at all necessary for your specific business.

Configure SNMP For Cisco Pix Running V7.0 of Code

2009-12-24T22:57:00.001-08:00

Enabling SNMP polling on a Cisco Pix firewall is configuration process that requires a few steps, but can yield valuable information. Getting SNMP from the Pix can include: number of connections, CPU utilization, memory utilization and interface traffic. Configuring SNMP with a community string, indicating the interface and allow this connection via an access-list are the steps involved.

Login to your Cisco Pix and enter configuration mode. You need to enter specify the host IP address of the host or networkingg monitoring station that will be polling the pix, the interface and the community string to be used. The Pix is very specific, all these variable must be correct in order for data to be gathered. The commands are (example commands from a Pix running 7.0 code). SNMP - server host inside 10.1.1.1 community SECRET.

This enables one host to connect and gather data from the Pix using the configured SNMP string. The access-list on the interface 'inside' must be configured to allow this connection. Many inside interfaces simply have an "any any" access list. Whatever interface the polling station comes in to connect on must have an acl entry allowing the communication.
The command for the access-list is: access-list inside extended permit tcp host 10.1.1.1 eq SNMP.

Once SNMP is enabled on the pix and communication is confirmed from the 10.1.1.1 host, you can then walk the pix for snmp data. You can also use MRTG's configmaker to generate a config file for interface traffic graphing of all the interfaces.

PC Repair - At My Home Or Should I Take It In?

2009-12-24T22:56:00.001-08:00

When your home PC has decided to opt for early retirement it is usually a madly infuriating situation. You may spend hours trying to figure out what you did wrong. Was it the kick for shutting down without asking? Was it the right jab for asking if you want to shut down when you've just told it to? It was probably neither but inevitably it's time to call in the experts. The question is who and how?

Usually the key questions is whether to call the PC doctor round or whether to unplug everything and take it back to it's birthplace or some other computer hospital on the high street.

Many people think of the PC in much the same way as the family car. They have a garage that they trust and similarly they have a PC shop they trust. But your car is mobile and if the garage hasn't repaired the problem you will know right away. Not so with PC's.

My parents recently took their PC to a repair shop. Unfortunately I wasn't in the country at the time to fix it for them. After 2 weeks the PC was ready along with the $150 bill for replacing the motherboard. When they took it home and assembled it they were quite dismayed to find it still didn't work. After a one day of swapping connectors and calling back to the repairers they got it working. This seems all too common a problem. Many times the fault is incorrectly diagnosed at the shop because the PC fixer only receives the dead box. Changes are made to settings and outputs that are not explained to the customer. When the customer puts it all back together at home all those wires look so similar and they end up in the wrong slot. Next, the PC goes back to the shop where the PC fixer and the customer have an argument regarding the "working" properties of the PC.

In contrast if you call a PC doctor to your house you can talk them through the problem. More importantly they can talk you through the solution and there is no disconnecting of wires and getting covered in dust. The only down side is in trusting a stranger in your home. Luckily almost all PC geeks don't have a dishonest bone in their body and they make enough money to ever be involved in any scams. Most people can judge character over the phone. Ask your friends who they would recommend. Be sure to get an estimate of the total cost for the job within the first 10 minutes of the PC doctor arriving at your house. If they won't commit show them the door.

Speed wise it's almost always quicker to get someone in. Many would argue that the repair shop will be quicker as it stocks the parts. If new parts are required there are so many variables these days that the repair shop is likely to order them in just like the roving PC doctor. Also, the price of parts is changing on a daily basis. It's in no one's interest to carry a large stock of parts.

Furthermore when the PC repair shop tells you that you are "top priority" be under no illusion that this really means "in the pile with everything else". The great benefit of calling someone in is that you know they are working flat out on your problem. You can watch them. If for some weird reason they don't like to be watched then show them the door. The whole point is that you can see what is going on.

How do I know all this? I've worked on both sides of the fence. I currently work as a roving PC doctor in Vancouver, BC but have worked part time in PC repair shops. For the reasons outlined above I wanted to work at people's homes. It's a great feeling when you can walk into someone's home, look at a problem that been driving someone nuts and have it fixed in 20 minutes.

Not all problems are fixable in 20 minutes. I know I might be biased but at least if you have someone round to your house they can show you exactly why it will take longer. If it's at the shop who knows how long the work took and if they used some old parts they had lying around! Happy computing!

Configure SNMP Polling Ability on Cisco Routers and Switches, To Enable MRTG Config Files

2009-12-24T22:55:00.000-08:00

Simple Network Management Protocol (SNMP) is a key feature to enable on any cisco network device so you can gather stats and other valuable data from the device. SNMP data can be sent from a failing device indicating trouble, interfaces down, environmental data and simple configuration changes. Contacting a device and pulling data can also provide key data to show health, traffic, errors and state changes of interfaces. No matter the size of the network involved, number of devices or size of the support team - SNMP should be enabled for even simple monitoring.

SNMP needs to have a community string set for read-only access and read-write access. For monitoring and health information, only enable read-only access. A unique community string and access should be configured for your Cisco device. The community string is the password polling devices will use to pull information, and the access list will restrict who can access data. A simple example is:

Cisco router/switch running IOS:
access-list 10 permit 10.1.1.1
SNMP-server community SECRET ro 10

Cisco switch running CatOS:
set SNMP community read-only SECRET
set ip permit enable SNMP

This will enable the router or switch to allow polling requests from any host on access-list 10, using the community string SECRET. Now that access is granted, a variety of information can be pulled, a common place to start is gathering interface traffic. From a monitoring station or software, you can then pull SNMP data from the device by walking the device and revealing information and SNMP OIDs to indicate health, traffic and start to monitor key systems.

An example is walking a device for interface data or using some mrtg unix utilities such as cfgmaker that comes with MRTG to then build a configuration file that gets interface traffic data from the device. If the community string is miss-configured when using cfgmaker or if the router or switch acl doesn't permit your host to connect, a working config file will not be made. Once a successful file is made, you can then use MRTG to poll the router or switch every few minutes, get that SNMP data, then generate logs and graphs showing traffic usage on a per port basis.

Understand the Routing Process, Part 2

2009-12-13T00:33:00.003-08:00

Static Routes

Statics are build in the same way as defaults, in the sense that they have a destination a prefix and a next hop, the difference being that a static route informs the router about specif routes rather than an "any" route like a default does.

An example of the static would be:

Ip route 20.1.1.0 255.255.255.0 10.1.1.0

The first part of the route, the address "20.1.1.0" tells the device that this route specifies the destination of 20.1.1.0.

The second part tells the router which part of the destination address in the first part of the address it needs to look at, the "255.255.255.0" instructs the router to look at the first three octets in the destination address and ignore the 4th octet. We could have written the destination address as follows "20.1.1", but the command line will not allow us to do that.

The prefix tells the router which part of the destination address the router needs to look at.

Example 1: The following two statics are now in our example router:

1: Ip route 20.1.1.0 255.255.255.0 10.1.1.0

2: Ip route 20.1.0.0 255.255.0.0 10.5.5.0

Our router receives a packet with the destination address set to "20.1.1.23", the router will examine the routing table and choose between the two routes. The router will choose 1 since it is a closer match for the destination address in the packet header. The second one is less specific or "broader" matching "20.1.0.0 255.255.0.0" meaning "use this route if the packet wants to get to any destination starting with "20.1. anything. Anything" whereas the first route matches "20.1.1.anything" making this route more specific for routing the packet wanting to get to 20.1.1.23.

The very first choice that a router makes is longest match irrelevant of how the it was learnt.

Matching Routes

What would happen if the router has two matching routes:

1: Ip route 20.1.1.0 255.255.255.0 10.1.1.0

2: Ip route 20.1.1.0 255.255.255.0 10.5.5.0

The static routes above have the exact same destination addresses and the exact same prefix lengths, so which one will the router believe?. The router will in this case begin to share the traffic across both paths, if this is your desired result then you are done, what if it is not, how do we force the traffic to take one route over the other?. This is achieved by setting what is referred to as the "trust-ibilty" of the route. Every route that populates the routing table is assigned an "Administrative distance" between 0 and 255. The lower the value; the more desirable the route. All static routes have an Administrative distance of "1". This value can be changed.

Administrative distance is a local value on the router; a router never advertises this to any other router.

1: Ip route 20.1.1.0 255.255.255.0 10.1.1.0 1

2: Ip route 20.1.1.0 255.255.255.0 10.5.5.0 2

Even setting the Administrative Distance to 2 makes route two less desirable. The router now chooses to use route one to pass traffic to destination network "20.1.1.0"

Now we know that the router makes the following routing decisions in the following order

1. longest match irrelevant of how the route was learnt

2. Lowest Administrative distance

Understand the Routing Process, Part 1

2009-12-13T00:33:00.001-08:00

Understanding routing processes

Routers route, that's what they do. A packet comes in and a packet goes out. What happens to the packet containing your data inside the router?, how does the router decide which output interface to transmit the packet out of?, what if the router has two routes to the same destination how does it deal with that decision making process?.

For a router to make a routing decision it needs to know how to get to the destination address which is described in the header of the IP Packet. Without this knowledge the router could ultimately drop the packet.

Our first job is to populate the routers routing table with relevant routes, we say relevant since routers will believe and trust any route placed into it's routing table and use it resulting in routing blackholes where traffic is lost in the network where the time to live in the packet headers expire and the traffic is then dropped.

Default Routes

There are various methods for populating the routing table, the most common of routes is called a "default route". A default route is written as follows (I am using Cisco command line)

Ip route 0.0.0.0 0.0.0.0 10.1.1.1

The route is simple to write and straight forward to understand. The first set of zeros after the "ip route" command which we will call the "destination" tells the router which destination this route represents. This route is effectively "matching" every single possible address that can be drawn up with the IPv4 address scheme.

The second row of four zeros which we will call the "prefix "shows the router which bits in the destination the router needs to look at.

Having any octet in the prefix set to all zeros (i.e 0 0 0 0 0 0 0 0 = 0) tells the router that it ought to ignore the corresponding octet in the destination. The order of the octets in the destination field correspond directly to the octets the second row.

The third address "10.1.1.1" is an example of what is referred to as a "next hop", (10.1.1.1 is an example address only for the purposes of this article only, your next hop will be different). The next hop address is the other side of the link on a point to point link or an interface in a multiaccess network like frame relay of Ethernet that can route the data.

The next hop does not have to be the address of the next hop, it can also be the local outbound interface.

All of our home broadband routers will have a default route helping the router to simply pass all traffic up to the ISP. Default routes are also known as "gateways of last resort"

Handheld Barcode Scanners - Its Uses and Convenience

2009-12-13T00:32:00.002-08:00

When it comes to retailing business as well as transportation, there have been many developments that have occurred over time. A large number of the operations have become quite automated and simplified for the benefit of consumers as well as the retail companies, which use such products. The main idea behind a barcode scanner is that it is held in the hand and is quite portable so that it does not have to be fixed at one place. This is why handheld barcode scanners are quite in vogue in this time and age. This is quite handy in keeping up with the times, where convenience as well as comfort is the most sought after in products and services around the globe.

A barcode reader or scanner is an electronic device which helps in OCR or optical character recognition. It consists of a light source as well as a lens and light sensor that can help in translating electrical impulses into electrical ones. This way, the matter which is located in the barcodes gets concerted into electronic form which it is then read by the handheld barcode scanners and the matter is decoded. This is quite a convenient feature as such scanners can be easily used at various places, in buses as well as retailing as well.

If you look at the retailing business, it has indeed been revolutionized by the use of handheld barcode scanners. In the good old days, when you went to some retail mart of a store, you would have to stand in line and have the store assistant calculate the expenses incurred manually using a calculator. Then the bill would be generated manually which would mean the spending of time. All of this can be easily avoided by using handheld barcode scanners. With these scanners one can scan the bar code on the product which is then fed into the machine directly and the price of the product is recorded after which it is fed out as a printed bill. All of this saves a lot of time and makes it possible to make the retail operations quite simple as well as streamlined.

The use of handheld barcode scanners in buses or other forms of public transport is also now well documented and wide spread. There are many bus companies that use these in order to read the pre-printed bus tickets that travelers use. This is very much convenient as this prevents the use of the manual tickets which was a cumbersome and time consuming process. This is why it always helps in using barcode scanners which are all so handy and convenient to use. There are many of these which can also be used at varying distances which make them so very simple as well as flexible in usage.

What is Broadband?

2009-12-13T00:32:00.001-08:00

When the internet first came about the only way to access it was by using a computer to dial a connection to your internet provider using a modem and your telephone line. This was great when the internet first came about as webpages were very simple, businesses mainly used it for email and it wasn't used that much and not by many people. Once the internet started to grow, you were now able to access your business computer from home, watch videos online and access social networking sites, dial up started to become a thing of the past.

Dial up internet had a few drawbacks that would eventually find people dumping it for faster internet connections that wouldn't tie up your phone line, cost you a local call when you wanted to connect, would download webpages, emails etc a lot faster and would offer a lot more flexability when it came to networking and being able to travel and access the internet at the same time. The new types of connection were then referred to as Broadband as the connection was a faster (the bandwidth was larger) speed. Broadband is basically a marketing term and there are a few types of internet connections that fall into the "Marketing Term" Broadband.

ADSL - This type of internet connection uses an ADSL modem which connects to your phone line, downloads anywhere from 6 - 400 times faster than dial up but doesn't tie up your phone line meaning you make and receive calls while accessing the internet. There are many providers who offer ADSL and a few different speeds available. The two types of ADSL are ADSL 1 and ADSL 2+. Make sure to shop around if your looking into getting an ADSL or ADSL 2+ connection as different providers will offer different speeds at different prices which you will be amazed at how much it varies.

Cable Internet - This type of connection is only available in areas which have dedicated Cable Internet cabling installed. This type of connection uses a dedicated cable from the street, only provided by Telstra or Optus which doesn't need a phone line at all and downloads at speeds similar to those of ADSL.

Mobile Broadband or Wireless Mobile Broadband- This internet connection uses the mobile phone network and can be used anywhere you get mobile coverage or where your provider provides you coverage. There are a few providers you can choose from which offer different coverage areas as well as different prices, so once again shop around and ask about both coverage and price. This type of connection can be expensive and vary alot in speed, I would only recommend this as a second internet connection if you need the internet on the road or when cable or ADSL is not available.

There are other types of internet connections that are used but these are the most common types that are in use today in both Home and Businesses. When choosing a type of internet connection make sure to look at all your options and to find exactly what sort of speeds you will be getting, what sort of download limit and how much.

In this case, the battery life will vary based on wireless usage, such as shopping the Kindle Store and downloading content. Everyone will never deny the idea that it is the real great worthy investment you should consider buying soon.

VAR Issues - "Cheap" Usually Means Scalability, Service, and Reliability Are Sacrificed

2009-11-24T08:21:00.003-08:00

Value Added Resellers (VAR's) come in all flavors, shapes and sizes - they provide a vital service to IT departments who are suffering from severe budgetary constraints, staff and skill shortages and issues in implementing and managing increasingly complex solutions. Successful VAR's are those who are delivering skills, customer service, bottom line improvement and are cost effective, but unfortunately, customers frequently confuse "cheap" with "value added".

Being cheap is not a bad thing - in fact it can be excellent! Cheap is not a good thing when it places constraints on future development and adaptability of the network. It is a definitely bad thing when the "cheap" solution subsequently incurs excessive management costs or worse, a serious management issue because the solution is failing users and business expectations.

No IT manager likes to be in the situation when they are called in to explain why a solution implementation is over budget or worse, considered to be a failure!

Frequently, cheap means that the solution cannot be scaled up if it is a success or simply to meet the needs of a growing company. The VAR usually is the constraining factor in these instances because solution substitution is rife in the IT market - it is not fair to say security solutions are like commodities but it is not a far stretch to make that conclusion from the lofty heights of the boardroom. No, in practice, it is the VAR you select to partner with, who is the constraining factor in exploiting or upscaling a solution for the business.

Typical reasons for this include the fact that the VAR is cheap. Cheapo charging VAR's do not usually have the financial foundation to continue with developing their own skill sets which you rely upon to be delivered into your own operation. They usually do not have the breadth of support from solution providers - particularly watch for a VAR with only a couple of certifications but who claims to provide a wide range of services.

Cheap also means sub-standard or no realistic SLA when it comes to customer service.
Picture the scenario where you implement a solution the users love - adoption is widespread and the application become s mission critical, at least in the minds of the board room and staff relying on it. Unfortunately, the application is hosted online somewhere in the clouds by the VAR who is unable to afford enterprise class connectivity. Now you have the telephone ringing incessantly as everyone from the VP Sales closing a deal in California to the customer service reps in your NJ call center suddenly find they can't do their jobs.

In turn - you make the call to your VAR - ask yourself what you are going to get, a voicemail or a person?

Ask yourself the same question except it is 3am on Christmas Day and the application is delivered over the WAN to 4 continents and every time zone?

This is where "cheap" simply means "bad". The answer is to focus on cost-effective solutions which demonstrate clear ROI and are backed by a VAR which has the substance to deliver the SLA you need and can afford. In these instances it is better to consider a VAR which is charging "appropriately" as a better measure of whether it is itself, delivering "value-added".

We Are All Corrupt

2009-11-24T08:21:00.001-08:00

This article will not only show how you can help raise standards on the Internet but will also complement your business activity and improve your lifestyle. Some of us have experienced fraud on the Internet and are annoyed that people can be so dishonest.

Many people have become suspicious of all business opportunities and refuse to part will their money.

What you are about to read will change the way you view life and approach your business activity, in a unique logical way. If you consider you are a person that respects your potential customers, please read on - If you do not think your customers require careful consideration and respect, thank you for your visit.

Title: Corrupt.

For the benefit of visitors that do not know the Definition of the word Corrupt - I Have listed the detail below:

Make Putrid.

Deprave.

Taint.

Bribe.

Tainted.

Infect with ERRORS.

The Definition of the word: ERRORS - is as follows:

Deviation from truth or what is right.

Mistake.

Blunder.

False.

Offence.

This means everyone of us is corrupt. A simple example we are all infected with errors. We corrupt each other, which in turn create problems for us all. We are all Computers. As we communicate with each other, we program one another. We are all 'Teachers and Learners'.

The errors we are infected with are caused by Eager Desires we all possess, within our emotions.

Greed - To gain material wealth causes some people, to lie, cheat and steal, which in turn affects us all. The majority of people throughout the world are law abiding and considerate to others and try to control the minority that are not so law abiding. Computers are helping us communicate with each other faster but when computers become corrupt they infect us all with errors, which cause us problems.

When you sit at your computer keyboard, how calm and patient are you? If you are not patient, you will begin making mistakes, which in turn will reflect on the formation you pass to others and corrupt, not only, your own computer but also other computers.

The written word is powerful because it can and does affect the emotions of others. The words you write are based on your level of consideration and care for others. The words you write can also be interpreted in different ways. If you deliberately write to people to buy your products by telling a lie, you are helping to corrupt computers because information passed, from one computer to another, results in computers and their owner, being corrupt.

Honesty, on the Internet is hard to find because every one that is trying to make 100's of 1,000's of dollars each month, are encouraged to part with their money with the promise of riches. This in turn causes the person that has parted with his/her money, to encourage others to part with their money, which finally results in many people being disappointed.

The key to success is within our emotions. If we want something eagerly enough we will achieve it, with enthusiasm and honesty. If we are dishonest we only fool people for a short time. Dishonesty infects computers and their owners with errors and in time it will be virtually impossible to make money on the Internet, unless we prove to each other that money can be made without investing a penny. It is logical that if money can be made from a product or service, it's not necessary to ask for money upfront, if the product or service is of real value to the consumer.

Sending out emails is thought to be the most profitable way of promoting products. The number of emails being sent out is increasing and people are being encouraged to send out millions of emails each day, based on the principle that some will be read and attract orders. No doubt they do attract orders but not enough to justify filling inbox's with unwanted emails.

Computers we are and computers we own will ensure that in time we will be less infected with errors. If you want to be less corrupt just be patient and considerate to others. Our computers are only corrupt because we are corrupt. When we sit at a computer we need to recognise that a computer is only as corrupt as it's programmer.

This worlds people are corrupt because we all contribute to the errors that exist within us all. If I said to you, "you are corrupt", you would probably be annoyed and insist you are not.

I am corrupt because every time I say something that is untrue, whether it is intentional, or not, that untruth is passed on to others, which corrupts them.

How can we help corrupt computers to be less corrupted?

The List that follows will not only help you to be less corrupt but will also help to remove errors from your computer so that it is less corrupt:

Be Patient.

Try to be truthful.

Stay within the Law.

Double check the information you type into your computer.

Pass this website to your family and friends - so that, they too, can boost their income.

Computers are here to stay and if we want to gain from their communication with each other, we must try to keep them free from errors, which in turn will save us all Time and Money.

Why are we corrupt?

Because we are not perfect, we have been infected with errors, since our birth. We are born with an awareness that is controlled by our body. It's our body that's corrupt.

When you purchase a computer, take it out of its box and set it up ready to use, you have a perfect route for communicating with every computer in the world.

A "Full Stop" - typed on a computer keyboard, represents, corruption to the ultimate point of discretion. To give a simple example, when you type a website URL, consider the consequences by failing to type a full stop at the appropriate place. The results can be astronomical and disastrous, even though it's such a tiny error. A Full Stop is Gigantic to a computer programmer.

Trust on the Internet, is fast disappearing. Everyone knows that dishonest people control computers it's getting harder and harder, to make money on the Internet. Those that are honest will succeed providing we help each other, remove corruption by being Patient And Considerate To Others.

Unhandled Win32 Exception Errors

2009-11-18T03:32:00.001-08:00

Unhandled Win32 Exception errors can show up anywhere in Windows. Whether you are just surfing the internet, listening to music or working on a document, such errors can show up again and again and make themselves an annoyance.

The errors can be caused by a program that has not been installed properly. If you know which program is causing this, uninstall the program, and reinstall it again. Check if there is an updated version of the program, and if so, obtain the updated one and install that instead. To minimize conflicts between different programs, you may also want to consider uninstalling programs that you don't need, additionally clearing up some free space in the process.

Be sure to run Scandisk, which is a program bundled with Windows, to check whether there are any bad sectors in your hard disk. Bad sectors corrupt files and data. If a program file is located in a bad sector, it can cause Win32 exception errors.

If these errors occur when you are using Internet Explorer, uninstall any browser add-ons one at a time to see if the errors disappear. Very often, add-ons can give problems if they are not programmed properly.

It is advisable to perform a full registry scan and repair. You can do this by using a registry cleaner. A registry cleaner is a software that goes through the Windows registry to find errors and repair them. Problems in the Windows registry are the main causes of errors in Windows, and so it is important to fix the errors in order to keep the system in good working order.

Blue Screen Error Fix - Why & How to Fix Blue Screen Errors

2009-11-18T03:31:00.000-08:00

Do you have the dreaded BSOD (blue screen of death) and are in dire need to find out how to cure it? In this article I'll explain exactly the methods you can use now to fix your error.

Always Has Been And Always Will Be

It has always been like this. Throughout all versions of Windows that I can remember, at least since Win 95, the BSOD has been part and parcel of the Windows experience. Even Bill Gates had one when he demonstrated plug and play capability at a large conference! The good news is that this means that today we have a good idea of what can cause one and therefore how to go about fixing blue screen errors.

First Read The Error

Sometimes an error will flash for barely a second - in those cases you might find a digital camera to be useful. Otherwise the error message normally stays on the screen indefinitely. Much of it won't make any sense to you but what you should do is to look out for anything that says "hard drive failure" or similar. Basically, if you have an error relating to the hard drive then you must buy a new one - the old one is broken or will fail imminently. Luckily, only a few blue screen errors are like this.

Now Fix The Blue Screen Error

Luckily most people do not have a broken hard drive. The vast majority of blue screens are caused by a computer that is riddled with Windows registry errors. The absolute best way to cure these errors is to get yourself one of the best registry cleaners. With these you can click a single button to run a deep scan of your registry and entire computer. Then another click will fix all these errors and therefore the blue screens.

What to Do If Your iPod Or iPhone Stops Working

2009-11-18T03:30:00.000-08:00

Some people get very attached to their technology and when it breaks there is a serious problem because unique files are on that piece of technology or entire music collections are downloaded on it, for example. It can be very frustrating also because many people do not know how to fix technology since it is so specialized. If your iPhone screen breaks for some reason or you need new ipod parts it is important to know exactly what to do in order to get everything fixed properly, with as little recovery of files as needed. In this article, you will find the steps that should be taken if technology that you own fails you:

1. Research online what your problem may be by looking up customer reviews or problems on the internet. Most of the time, others have had similar problems and have posted how their issue was resolved online. You should also research how customers feel or rate each company may try to get to fix your product. If the customer satisfaction ratings are low for a company, you would probably want to pick another location to go to take your piece of technology.

2. Decide where you would like your piece of technology to be fixed. Some people like to go directly to the store where they got their item, while others like to try a private company that specializes in just fixing their product. The advantage of going back to the store where you got your item is that they normally have the most readily available parts; however, it can take an extremely long time to get your item back because usually customers do not have to pay for the service to have their item fixed by the store where the item was purchased. A private company can be a very good choice because since you are paying for the service they will try to get your product back to you as soon as possible. Also, since these private companies are usually specialists, they will most likely be very knowledgeable about your product.

3. Once you have decided where you will take your product, you then need to make sure you understand what the people who are fixing it are going to do and when they will have it back to you. If you do not understand what the people who are fixing your product are doing, you may not know how to work it in the future or they may not fix the problem properly and something could go wrong again. You need to know what problem was fixed, so you can check the work after the people you are hire are finished with it.

It is important to remember that you do not have to have your product fixed at the place first decide on if you feel they are trying to cheat you or if you feel they do not know what they are talking about. If this occurs, simply do some more research online and try somewhere else.

Computers and Internet - An Irrepressible Evolution

2009-11-18T03:29:00.000-08:00

From vacuum Tubes to microprocessors, computers have continued to evolve unlike the human race. It was in the early 80's when IBM introduced their first computer to the home user. It was fast, cooler and meaner. This machine sat placid on your desk and did anything in a jiffy as opposed to its grandfathers. The man behind the success was none other than the Intel microprocessor. This chip consisted of several transistors which regulated information electronically. It would do all the tasks in the world and still fit in your palm.

Today's microprocessors are different from its predecessors. But they are developed around the same architecture and logic. These little machines have made computers smaller and easier to interconnect. Until then, the internet was more or less in the implementation phase. It was accessed only by computer experts and other scientists. Personal computers made more universities and organizations interconnect. This enabled the comparatively lesser learned people to communicate with others around the world.

Since then, the average computer knowledge has moved up from merely turning it on and off. Advances in the field of internet brought about the TCP/IP protocols which provided the users with applications such as the HTTP (which runs the World Wide Web), FTP and the very popular e-mail. This protocol suite helped in meeting with the ever rising demands of the internet. It is a service which turned the internet into a necessity and propelled businesses, produced career opportunities and brought awareness by educating.

The current Internet Protocol in use is IPv4. It has the capacity to provide four billion unique addresses and remains the most widely deployed Internet Protocol. But address exhaustion will take place as the number of users will increase. This emphasized the need to come up with the next generation protocol called the IPv6. It is not a completely different protocol but a conservative extension of IPv4. Large address space, reliability and security are its advantages.

Besides the Internet, computers needed to have all the tools to address several high end applications. Intel and AMD declared war which resulted in some mind blowing technologies. Intel produced some really good processors like the core 2 duo, core 2 quad and core i7. AMD has its own line of processors which are more or less similar in performance to those of Intel. On the other hand, impressive operating systems were written to exploit these little machines.

Ever since 'Windows 98' burst on the screen, its been Microsoft all over the user market. Linux and Mac OS X are becoming increasingly popular and posing stiff challenge to Microsoft's line of operating systems. With growing internet crime, operating systems will have to start providing staunch security. This leaves us at a point where we need to reconsider our priorities and choose the right operating system. New products and technologies keep coming in the market. Each one has its own pros and cons.

A good suggestion would be to play the waiting game. But an enthusiast will refuse to agree. CDs are disappearing. Blue-Ray discs are relatively new. Hard drives have got portable. PCs became laptops and laptops became notebooks.

And then there is the Fifth Generation of computers. These computers delve into speech recognition and self-organization, leading to what is popularly known as 'Artificial Intelligence.' These computers will effectuate a radical change. Scientists, over the last two decades have been able to achieve the feat of creating humanoid robots. The 'Asimo' from Honda is a noted example. The purpose for their creation is a debatable topic. But the widely accepted purpose is to facilitate the advancement of human beings.

All of us want to be a part of computers and internet either at the user or developmental level. These fields have been characterized by constant progress and breakthroughs. They remain the most talked about domain and have moved far ahead from just being a medium of communication. Looking at the previous creations, we realize to have come a long way. We envision an endless path with unimaginable possibilities and their irrepressible evolution.

Some Types of Network Security Breaches

2009-11-11T05:32:00.003-08:00

The online world has grown in leaps and bounds in the last few years. This provides the public with some amazing resources - the ability to access information with the touch of a finger, the ability to communicate via fast and inexpensive methods, and more functionality and ease of use are being introduced every day. Unfortunately, as with all good things, there is also a dark side.

While there are plenty of people who use the internet and computers responsibly and honestly, there are predators and hackers out there who spoil the fun for everyone if their dirty deeds go unchecked. There are a lot of ways for these people to compromise your computer and your network. Below we will review just a few of the ways that your network can be compromised.

Two destructive network breaches fall under a category known as "destructive behavior." One involves the complete obliteration of data within your network. It is called "data destruction" and it is just what it sounds like. It happens when someone breaches your network and deletes data. If your network is business-related, this can be devastating. Experts say that it is no less destructive than a fire that destroys your computer equipment.

Some perpetrators have more than simple destruction in mind. They do something called "data diddling" which means that they alter the data in your system. They might change data in spreadsheets or other documents, or they might tamper with your accounting system. Some examples of things that have really happened involve the accounting system specifically. "Hackers" have broken into a network, accessed the accounting system, and changed the account numbers on direct deposit paychecks to go into their own accounts. Thefts like this take some time to track down - first the employee has to not get paid, investigations have to be made, and someone has to think to double-check the direct deposit account information. In some cases, companies have cut new paper checks and it has taken months to retrieve the lost funds.

Another way in which networks are vulnerable is in the realm of confidentiality. A lot of times, companies possess information that, if shared with a competitor, could be very bad for business. In this case, predators are not looking to alter or destroy data, they are merely trying to find out information they're not supposed to know. If someone were to find out financial performance information before a public release of said information it could affect the stock negatively. If a company is planning to roll out a new product and someone gets that information and gives it to a competitor, or leaks the information to the public, it could hurt the company's sales. Even more frightening is the possibility of someone breaking in to view confidential employee-related data - like home addresses, social security numbers, and bank account information.

Network Security - Penetration Testing Explained

2009-11-11T05:32:00.001-08:00

A penetration test (in the IT vernacular referred to as a "pen test") is also known as "ethical hacking", and this network security tool provides an essential function in vulnerability assessment. By actively seeking out and deploying attacks and penetration efforts against your network, you are more likely to uncover vulnerabilities and be able to take action to block holes in your security and pre-empt attacks on the perimeter defences.

Penetration testing includes both script-based and human-based attacks on the network in order to seek out and exploit vulnerabilities. The difference between this and say, criminal hackers looking to cause mischief or theft of data, is that you control the "attacker". The "attacker" reports back to you on whether they were successful and if so, how to stop such an attack from being successful in real-life. Penetration testing will reveal network security holes but more than this, it will be able to provide you with a realistic risk assessment including the impact on your business should such an attack succeed. Knowing what such an attack may cost your business will provide you with the ability to quantify the business risk and determine whether you do in fact, need to implement a solution.

"Black Box Testing" involves a penetration test where the attackers have no knowledge of the network infrastructure. They are working from what a real, external hacker would be using - online connectivity and any human intelligence or reliance on human nature, in order to discover vulnerabilities.

"White Box Testing" involves attackers who have full knowledge of the network infrastructure and are seeking out vulnerabilities and scenarios to take advantage of perceived weaknesses.

An intermediate form exists, known as "Grey Box Testing" where some knowledge is provided, known also as "partial disclosure".

The aim of these differing forms of testing is to compel imaginative ways to hack into the network, compromising network security. While having full knowledge of a system may lead the ethical attacker to use an obvious defect in network security, they may pass over and completely miss a less obvious but more severe vulnerability. Blind or black box testing does not allow for precise testing of certain components of the network because they don't know how the network is established but, this form of testing does lead to more imaginative attack scenarios being developed and hence, a more realistic prospect of stopping a real attacker with mischief in mind.

Penetration testing should be a regular scheduled activity and performed at least once a year and every time the network infrastructure is added to or changed. Penetration tests are also a serious component of risk audits conducted to determine network operation and integrity. Script-based penetration testing is relatively inexpensive because of the level of automation involved and is eminently suitable for white box testing. Black box testing, on the other hand, is labor intensive because it involves real people emulating real life hackers and such a penetration test will involve more than simply running an online attack against the network, for instance, rummaging through company trash for computer information, and this dramatically increases the cost.

Internet Telephony Explained

2009-11-11T05:31:00.001-08:00

Using your company network as the backbone for making telephone calls is not a new concept, in fact it has been around for several years but recent developments in technology has increased the rate of adoption of internet telephony. Internet telephony goes by numerous names and acronyms - VOIP, Voice Over IP (IP stands for Internet Protocol), IP telephony, broadband telephony and VoBB (Voice Over BroadBand). Skype is the first widely adopted application which uses the internet backbone as the basis for transmitting voice and video call data.

The advantages of internet telephony are numerous, not least the cost savings associated with running telephone calls over the same network as the company network and internet. By combining the two applications - use of the web and making telephone calls - only one network is required instead of two separate telephony and IT networks. In a wider context, telephone and internet service providers (ISP's) can use their existing network, and network security , infrastructure to deliver services to customers. This is why it is so common to find cable/telephone/internet access all bundled together from companies in the business and domestic customer markets.

The cost of making calls also drops significantly as the internet (which is free) is simply being used to transmit your call in the form of data which is reassembled at the other end of the connection. A user simply needs to pay for internet access and this bypasses the need to pay a telephone company for the service. The cost savings become even more apparent when you consider that the internet backbone is just as capable of delivering your voice or video data to Australia as it is to the cubicle next door in head office.

Issues arose with internet telephony because of the poor call quality which was frequently experienced by users. Call quality has dramatically improved with better technology and data transmission techniques such that call quality is in many instances just as good as a land line call. A further drawback was the inability to make telephone calls if the internet connection was down - as internet telephony relies on the internet backbone to transmit the call, if you cannot access the internet for whatever reason, you cannot use the internet telephony service. This has led to criticisms of VOIP for its lack of redundancy but installations frequently run hand in hand with a fixed line system and still deliver significant cost savings.

Modern internet telephony systems use bandwidth with a high degree of efficiency and as this limiting factor has now been removed, more and more businesses are performing the migration of their business telephone service to IP based services. It is not just the cost savings which can be achieved which is the business driver but the functionality which can be delivered. Internet telephony encompasses much more than voice calling and includes video and web conferencing, interaction with email systems, multiple and anywhere/any device utility for making and taking calls, faxes and emails and much more. This is referred to as "unified communications" - treating any communication which can be made or taken using any device and internet telephony provides the basis for this merging of communications technology and application.

Domain is Blacklisted

2009-11-05T04:03:00.001-08:00

Spammers are always looking for doorways to send spam emails. If your exchange server is an open relay which can easily help spammers to pass through, then many mail servers and ISPs will blacklist your domain. When you find out that your domain is blacklisted, you should take steps in removing your domain from that list so that your subscribers can receive your mail without fail. However, finding whether your domain is in the blacklist is the tricky part here and it can't be done without a proper tracking tool.

Spammers use spoofing to conceal their original identity. When your ip address or domain is used by spammers consistently to send out emails, then it is obvious that mail servers will consider your ip address and domain to be a spam. Popular domains are also commonly used for spoofing, but since the servers are aware of those domains, the whole domain will not be blacklisted. When your less known domain is in blacklist sites, mail servers will immediately blacklist the whole domain.

The only way to pass blacklist test is when you have your domain name is in the whitelist. Mail servers update their blacklist sites from time to time. When you contact the mail servers and prove them that your domain is not a spam, then you can whitelist your exchange server. However, after whitelisting, you should follow procedures to prevent spammers from using your exchange server to send spam emails.

Knowing domain is blacklisted is very crucial to take the next course of action. A proper mail monitoring and tracking tool which ensures email deliverability will check your domains and ip addresses against major blacklists popularly used by mail servers. All your emails will be tested against blacklists and any dispute will be reported to you. With this report, you can take steps to whitelist your domain to get in touch with your subscribers.

Check Blacklists

2009-11-05T04:00:00.002-08:00

Blacklists are found in thousands on the internet. Some of these blacklists are available for free while many providers buy authenticate blacklists from various legitimate internet monitoring groups. Basically, these blacklists contain ip addresses and information about emails used by spammers. IP addresses of mail services sending out spam emails will also be included in the blacklists. Simply, all kinds of blacklist sites will be available in blacklists.

ISPs and bandwidth providers will check blacklists before delivering any email. IP address of the sender is checked against blacklist used by the provider. It is not possible to find out what list is used by the ISP and bandwidth provider. Aside from public blacklists, companies will have private blacklists for more detailed checking.

Blacklist test is employed by email monitoring tools. These tools will use available known blacklists to perform the test. When your IP address is blacklisted in any of those known lists, you will be notified. Groups that are interested in keeping the internet clean will be engaged in creating these blacklists and hence, if you contact them, you can get your ip address whitelisted.

Many entrepreneurs lose their subscribers mainly because they don't check blacklists. While it is practically impossible to manually check your IP address against blacklisted list of IP addresses, a tracking tool can be of great help. If you think that you have to spend a great deal of money to buy a monitoring tool, then you are wrong. You can easily find a good email monitoring and tracking software that can help you in doing all kinds of blacklist tests.

The tool you use for checking blacklists must constantly update itself because everyday, many new domains and dns are added to the blacklists by internet users. Also, the tool must be able to use as many blacklists available to increase email deliverability.

Mail Delivery Tracking - Spam Filter

2009-11-05T04:00:00.001-08:00

If you want to know whether your emails reach the recipients inbox, you will need to use a mail delivery tracking application. This software does several spam checks which is used by various email systems. When your email fails most of these checks, then it is time to find out where the problem is because only when your email pass the spam filters, it will reach the recipients' inbox.

Spamming is today widely hated and hence, email service providers set their filters to highest possible level trying to prevent any kind of spam. While this is good for the recipients, many times the filter will disallow legitimate emails from being sent to the recipients. Without a mail delivery tracking system in place, you won't know whether your email is in the spam folder or inbox of the recipient.

Spam monitoring is the main job of email systems because customers of those systems will not be happy when their inboxes are filled with spam emails. Even though your subscribers are interested in your newsletter and emails, they won't receive those emails when the spam filters filter out all those emails.

You can also instruct your subscribers specifically to include your email address in their whitelist to pass spam filter. However, the subscribers who will actually do this extra step to receive every email from you are a few as compared to the total number of subscribers in your list.

Hence, with the email marketing deliverability tracking assistance, you can get some insight about the filters that will disregard your emails. Some filters will check the subject line and contents of emails for spam words. Without any reason, spam filters may consider your email as spam when you have some affiliate links in your emails. Soft bounces must be known to you because with little improvements in email marketing campaigns, you can easily find ways to pass spam filters in the most legitimate way.

"Distributor-Modeled" Training

Can your distribution partners access your training-services infrastructure, to quickly train their employees about your products, while also building a university-like organization to deliver and track training of their (and your) end customers? In a distributor-oriented organization, your LMS should be able to support many levels of such "Distributor-Modeled" training... and deliver benefits to you, your distributors, and your customers.

At the simplest level, your distributors would be able to send people to your LMS training site, and have them registered as customers of each distributor. This would allow you to generate reports about courses delivered, classroom scheduling, and training results for each distributor's customers over the past month, quarter, and year. It will also allow you to create more complex training solutions for heavy users of your training services, while being able to identify distributors who might benefit from special training promotions.

The next logical step would be to give distributors themselves restricted administrative access to your LMS. In the simplest implementation of this model, the distributors would be able to:

• Modify training accounts for their own customers.
• Assign online training.
• Enroll customers in your LMS' scheduled classes.
And on a more advanced level, distributors could:
• Assign Training Certificate Competencies and their related learning events to their customers.
• Create and run their own onsite training sessions.

This model will improve your relationship with distributors, enable you to provide them with more services, and reduce the training-administration overhead for your company. Some of the advanced services it also enables are:

• Linking a class with a specific distributor, so that only that company can enroll its customers in the class.
• Customizing training catalogs, with a reduced set of courses/classes and/or individualized course/class pricing for specific distributors.
• Offering these catalogs with either a prepaid training-account that end customers can tap, or a standard e-Commerce "customer pays" set up.
• Allowing distributors to order training for their customers.
• Creating special reports to track the training and certifications of distributors' customers.
• Setting up customized user-interface paths for distributor-administrators, to control their access to specific LMS functions.
This model also allows you to create a "Super Administrator" role for more advanced distributors, which allows them to perform such functions as:
• Creating classes.
• Entering class results.
• Creating user accounts.

And finally, to extend this Distributor Model to an advanced level, think about branding separate campuses for each distributor (Figure 3). This allows you to create completely separate, distributor-branded training sites for each distributor within your LMS, while still permitting you to do complete rollups of all their training information and results.

Among this model's advantages are that it allows distributors to:

• Keep their corporate branding throughout all customer training materials.
• Create one-to-many levels of structured reporting, allowing each distributor to produce hierarchical training reports for its own operation.
• Receive a single point of contact in your company, with Registrar rights and privileges, to help distributors maintain their training operations.

So if they fit into your operation, these three levels of Distributor-Modeled training can improve your relationships with your distributors and provide them with much better levels of service, support, and training functionality. These models can also both save you money (through reduced administrative costs) and increase revenues (through branded training campuses).

2038 - The Next Computer Time Bug

2009-10-21T22:24:00.001-07:00

Remember the turn of the millennium? Whilst many of us were counting down the seconds until midnight, there were network administrators across the globe with their fingers crossed hoping their computer systems will still be working after the new millennium kicked in.

The millennium bug was the result of early computer pioneers designing systems with only two digits to represent the time as computer memory was very scarce at the time. The problem didn't arise because of the turn of the millennium, it arose because it was the end of the century and two digit year flicked around to 00 (which the machines assume was 1900)

Fortunately by the turn of the millennium most computers were updated and enough precautions were taken that meant that the Y2K bug, as it became known, didn't cause the widespread havoc it was first feared.

However, the Y2K bug is not the only time related problem that computer systems can be expected to face, another problem with the way computers tell the time has been realised and many more machines will be affected in 2038.

The Unix Millennium Bug (or Y2K38) is similar to the original bug in that it is a problem connected with the way computers tell the time. The 2038 problem will occur because most machines use a 32 bit integer to calculate the time. This 32 bit number is set from the number of seconds from 1 January 1970, but because the number is limited to 32 digits by 2038 there will be no more digits left to deal with the advance of time.

To solve this problem, many systems and languages have switched to a 64-bit version, or supplied alternatives which are 64-bit and as the problem will not occur for nearly three decades there is plenty of time to ensure all computer systems can be protected.

However, these problems with timestamps are not the only time related errors that can occur on a computer network. One of the most common causes of computer network errors is lack of time synchronization. Failing to ensure each machine is running at an identical time using a NTP time server can result in data being lost, the network being vulnerable to attack from malicious users and can cause all sorts of errors such as emails arriving before they have been sent.

Digital Gram Scales - Electronic Weighing Scales With Clinical Precision

2009-10-21T22:23:00.003-07:00

When excited people describe you how clinically precise someone had to be to achieve something great, you say a wow in your mind. Seriously, nothing in the world can be an optimized achievement unless the system is tuned to perfection. When it comes to measurement of weight for any purpose, a digital gram scale is the device that can get you accuracy at the extreme level.

A digital gram scale is an electronic scale. It is driven by the line power, and can also be driven by a battery. It has a weighing platform, on which you can keep the substance to be weighed. And it has a digital display on which the weight of the object is shown. The display will have a good contrast and a backlight. You would have an option of measuring the weight in terms of grams as well as ounces.

The accuracy of this class of devices is the greatest power they have. These scales are accurate to the decigram - that is one-tenths of a gram. So if you care about every gram of weight then this is exactly what you are looking for. No wonder the digital gram scales have become popular among food buffs, cooks who love to be precise, scientists who need to be accurate in weight measurement in their experiments, dealers of valuable metals such as gold and people form other walks of life with a need of being accurate about weights.

If you desire to get your own digital gram scale, then make sure that you buy one with a good warranty period. Buy a branded one - the scales are not expensive and it makes sense to go for a good one given the price tags. A digital gram scale can actually do wonders to your state of mind if the accuracy of weight matters to you and you are relying on guess, on non-digital weighing systems or on weighing systems owned by others.

How Can You Make the Best Use of Technology With Digital Weighing Scales?

2009-10-21T22:23:00.001-07:00

As technology has evolved, newer and better devices have emerged and have made noteworthy impacts upon the human society. Some of these devices are simple in nature and some are more complicated than the others. A digital weighing scale is one of the simpler devices that have played a distinct role in many corners of our lives.

Digital weighing scales are used everywhere nowadays. The older analog mechanical scales are quickly getting replaced by these scales. People prefer digital scales due to their clarity and accuracy. The scales operate electronically. They use electrical display boards that provide an accurate reading of the object's weight immediately. One can simply read the numbers from the board rather than trying to understand what the needle is pointing to. Obviously the scope of error is very limited here.

How can you benefit from such a scale? There are a number of ways.

* Merchants: If you are a merchant then you get to weigh your sell item perfectly. You don't try to interpret needle pointers and get accurate measurements. This ensures that over a period of time, you save a high amount of wealth that would be given away for free to your customer otherwise. For more valuable objects such as jewelry this is simply invaluable.
* Customers: You get the best value for your money, and can control the amount of your purchase to your precise requirements.
* Doctors: You get to measure the details of the patient's weight as you desire.
* Scientists: Your experimental inputs are perfectly weighted and given, and the results are perfectly measured. You get more perfect insights.
* Goods carriers: You get the right money for the goods your company is carrying on behalf of your client.
* Cooks and bakers: You mix your ingredients perfectly and produce the best of foods and bakery items. You control the dietary issues and are consistent in your cooking quality.

And if you are from another walk of life, you can probably relate how such accurate weighing capabilities may affect you going by the above examples.

Essential Computer Network Security Best Practices

2009-10-21T22:22:00.000-07:00

Network security should encompass all aspects of a network from the desktop to the perimeter. A multifaceted and multilayered approach to network security for any organization or business provides the ideal protection coverage against internal and external threats. For small networks or even a single computer, a router with integrated firewall is usually sufficient. For larger networks a dedicated firewall at the network perimeter may be more appropriate. A good number of dedicated firewall appliances can also provide secure Virtual Private Network (VPN) connectivity. The most common feature provided by dedicated firewalls is their ability to inspect, block and report malicious network activity usually initiated from the internet. Firewalls that provide this functionality are often designated as an Intrusion Prevention System (IPS).

A content filtering device is a good complement to a dedicated firewall. These types of devices usually include the ability to monitor, filter, regulate and report on all web related traffic. They are usually installed transparently in line between an internal switch and router or firewall. All internet inbound and outbound traffic is then forced to pass through it. This type of installation is often referred to as "bridged mode." Some content filtering devices can also be integrated with a network directory for individual, detailed monitoring of end user web related traffic. Microsoft Active Directory and Novell eDirectory are examples of directory services that can integrate with a good number of content filtering devices.

Desktops and servers should be protected by antivirus and anti spyware applications. There is a wide variety of enterprise level threat protection software available in today's current marketplace from numerous vendors. The ideal threat protection software should include at a minimum, frequent if not daily virus definition updates, centralized management and reporting, active protection and the ability to guard against unknown threats.

Another aspect of the network that needs security related consideration is what the users are allowed to do on desktops and laptops. Management may want to evaluate and implement access and rights appropriate for their environment and the nature of the organization. Should users be allowed to install software on their own or should the use of removable devices be disabled company wide are examples of issues that should be addressed when defining security policies and procedures.

Lastly, physical security is also important when considering all security related aspects of the network. Servers should be secured and access regulated and documented. It is also best to make sure that backup media is secured whether stored on-site or off-site. In conclusion, a proactive effort in utilizing these network security best practices coupled with consistent monitoring, constant re-assessments and adaptive reconfiguration are all essential in ensuring the safety and protection of an organizations data, intellectual properties and physical assets.

Online HTML Codes Tutorial - What You Need to Know About How to Learn HTML Basics Faster on Your Own

2009-10-03T06:36:00.001-07:00

Some tutorials found online contain HTML basics that anyone can easily follow even without prior background of the said computer programming language. Most of the time, these tutorials establish their lessons on a main objective. This objective usually revolves around a single thing which is to build a strong foundation of HTML lessons for a lot of beginners. Aside from this very important objective, these websites usually include in their lessons only the most common elements of HTML. Since building a website on your own is what these tutorials want for you, they will only include the necessary elements needed when a programmer is building an actual website.

An HTML code tutorial will not be effective if the user cannot really see how they are supposed to be applied when already building a real website. In short, it is important for these tutorials to show the students some examples of the uses of HTML codes. Lastly, all of these online tutorials want their students to really build a successful website over the Internet. And in order to do this, they also include information about search engine optimization. This may not be directly related to the actual coding of the appearance of the webpage, but it will really help in its overall success.

The good thing about an HTML code tutorial is that it does not only revolve around the codes itself, but it also includes helpful lessons that will stay with the students for a very long time. And these non-trivial lessons are far more important than the basic knowledge of how to design a website.

Apple iPod Repair and Parts Service

2009-10-03T06:35:00.003-07:00

It is often questioned whether it makes sense to purchase a new iPod or repair an old one. We always want the latest and greatest devices to add to our arsenal of portable media weaponry. When it comes time to weighing the cost and benefit of repair over that of replacement we need to consider a few options.

Why it makes sense to repair - Repairing your iPod has a few advantages including:

• Cost - usually the cheaper than buying new or even used.

• Environmental Consideration - repairing is a greener solution. It is a less environmentally impacting process. Repair shops only replace what's needed rather than throwing out the old to buy a new device.

• Features - in some cases there are features available with the older iPod that aren't available in the new. Take the 5th Generation iPod Video for example. You can have video output through the headphone jack whereas newer models like the iPod Classic are required to use a Apple Universal Dock Connector.

• Sentimental Value - believe it or not a lot of people are attached to their iPods. Why replace something that has been given to you, just because it breaks, when you can keep it working for many many years.

• Repair can make your iPod look like new again - A new faceplate and backplate will have you looking like new again. Let a professional replace your front and back covers and you will have a new iPod again!

When it makes sense to replace - replacing your iPod is sometimes necessary.

• In cases where parts are no longer available

• When cost exceeds - If the price of a repair is higher or near that of a new Apple iPod.

• In need of larger storage capabilities - With the conglomeration of large libraries of music there is a need for more space.

• Need for more features - We can understand the desire to move to a more robust iPod. Going from an iPod 4th Generation to an iPod Touch is a nice upgrade. The new features available in the Touch and Touch 2G are a big step up from the old photo generation iPods.

New generation iPods are getting more sophisticated. Additionally, they are also getting easier to break. With the addition of flash memory to many of the newer Nano, iPod Touch, and iPhone single repairs are getting pricier. There is no replacing of a bad hard drive anymore. Many of the boards have the memory in place and require full replacement of the Mainboard and memory modules. Screen replacement, a common repair, can require the replacement of multiple parts such as the digitizer and midframe.

Luckily for consumers repair options are available for almost any generation iPod.

These iPod Repair Guys will have you working like new once again. With costs rising for new cutting edge devices, who wants to have to replace it when it breaks?

YouTube Makes Video Watching & Sharing Easy and Addictive

2009-10-03T06:35:00.001-07:00

If you've mastered online photo sharing using a website like Picasa or through uploading to Facebook, did you know that it's equally easy to share videos over the Internet? YouTube is a website that makes online video posting accessible to virtually anyone with the ability to shoot video. Whether you want to share a video message with the world, social network friends or Grandma, YouTube has tools to make it easy and fun.

YouTube isn't just for hobbyists. It even has captured the attention of television networks and movie studios that use it to publicly post trailers or entire television shows. If you've sees a funny commercial that you want to show your coworkers, you'll probably find it on YouTube, too. And, if reruns on TV have you aimlessly channel surfing, check out original shows offered exclusively online by "Internet TV producers."

What It Is
YouTube is a free service that has grown and evolved into a powerful online community where people can watch, post and discuss videos. Anyone can visit the site and watch millions of publicly shared videos. If you want to comment about videos or share videos privately, you'll need to register as a user.

An Engaging Community
Technically, YouTube works thanks to Adobe Flash Video technology, but what really makes it work as an online service is its ability to engage users and create buzz. For starters, users can rate YouTube videos with up to five stars. Top-rated videos are more likely to be recommended to viewers or fall in the "featured" category.

On YouTube, it's incredibly easy to share your own or another's video content. You can email video links or use built-in, single-click tools for showing friends on MySpace, Facebook, Twitter, Digg and other social networking sites what you've been watching-and tell them what you think about it. If you have a blog or website, YouTube provides you with the code you need to embed videos, too. No matter how you choose to share, your friends will be able to share it with their friends who will share it with their friends who will share it with their friends.You can imagine how quickly a video can "turn viral."

After watching a YouTube video, the site makes every attempt to keep you engaged by recommending other similar videos you may want to watch. You can very quickly go from watching one video to spending your whole evening on YouTube.

Your Broadcast Station
If you are ready to share your own videos, there are several options for making your debut. You can instantly record and post video using your computer's webcam, iPhone 3G-S and some newer iPods. Although it may take an extra step or two, sharing digital video taken with a Flip video camera or camcorder is still noobie-friendly as long as the video is less than 2 GB in size and 10 minutes long.

When uploading a video, it's especially important to determine if you want it to be a publicly or privately shared. Choosing the private setting means only 25 other people will be able to access your video and you will not be able to use some of YouTube's video sharing features.

If you decide to share your video with the world, be sure to add tags. Tags describe your video and will help your video appear as relevant results to searches for the words in your tag.

Your New Obsession
If you haven't already tried YouTube, hopefully this brief introduction will give you the confidence you need to start exploring and experimenting. Whether you are a video watcher, video poster or both, YouTube has plenty to keep you engaged, informed and entertained. Here are just a few ways YouTube might enhance your life.

Video Watching

* See the Super Bowl commercials you missed while getting another snack.
* Watch news from other states or countries and compare it to local coverage.
* Look for your child's favorite shows or performances of his favorite songs.
* Find a person or "channel" with content you like and subscribe so you'll be notified about their new posts.
* Listen to videos. Some videos aren't videos at all but a way to post music, speeches or other audio content.

Video Posting

* Record yourself reading a bedtime book to your grandchild who lives far away.
* Create a video blog post so your readers can see you in action.
* Send video birthday greetings to someone far away.
* Share video of your child in her first performance with grandparents or other relatives.
* Record sports practice and make the video available to everyone on the team.

Some Free Utilities to Help You Work Better

2009-09-23T22:48:00.004-07:00

Everything costs money, and most of the time it's true that you get what you pay for. However, there are some free utilities that you might find useful for business purposes that I'd like to share with you.

The first is called Aero Snap. It's a feature that will come with Windows 7, so if you're planning on being an early adapter you don't have to worry about it. What it does is allows you to move any window you're using to the side of the screen, release it, and it'll automatically conform to a half screen window. If you have a big monitor, what this allows you to do is open two programs and look at them at the same time, which sometimes happens. Say, for instance, you have a bunch of numbers typed into a word processing program that you need to type into an Excel spreadsheet. You can snap one of the programs to the right, the other to the left, and instead of constantly flipping back and forth between programs or having to print your list out to work from it, you'll have both programs there readily and can just go about your business.

Do you have a fax machine? If not, you can still receive faxes from any source via email. There's a neat utility called J2 Messenger that's been around for years now. You just sign up for a free account, and they'll give you a fax number to use. The thing is, your fax number won't be local, but it works. To get a local number you have to pay a small monthly fee, but then you can use it to send electronic files as faxes if the need arises, which it often does. Since Vista didn't come with a fax program unless you got the professional version of it, which a large percentage of people didn't, this might be a way to help you get around that issue.

Something else about Vista is that Google Desktop, one of the best programs in the world for being able to find files on your computer, isn't compatible with Vista. There's another free program for that called Copernic Desktop Search, which is pretty good. It's free, which means that when you decide to use it you'll not only get a little bit of advertising, but it will also search the internet for your search term. That's a little bit irritating, but it will get the job done.

Once again, there's a superior desktop search program coming in Windows 7 if you want to wait for that.

At the Center of All Technology

2009-09-23T22:48:00.001-07:00

What comes to mind when your think of technology? For some people technology conjures up images of computer circuitry or the internet, for others the latest cellular communication devices or flat panel television sets are the first thoughts that pop into their heads. And for yet others space walks and Mars rovers come into their thoughts, but at the center of all of these different answers is one underlying theme, computer circuit boards.

Computers have greatly altered the way in which people work, communicate and associate with each other. The images that come to mind at the mention of technology often include a circuit board as the central focus of technology. And that is an accurate portrayal of what modern technology is all about. At the center of every electronic gizmo and computer is a printed circuit board. Printed circuit boards or PCBs as they referred to in the industry, have been included in many technologies over the decades. First introduced by an Austrian born inventor named Paul Eisler, in the 1930s, PCB manufacturing began as a military project within the US until the technology was released to the electronics industry after the end of World War II.

Since that time PCB manufacturing has evolved to become smaller and more intricate in the designs that are carved by lasers into the polymer layers that coat a copper plate. Copper being a conductor of electricity, is used in PCB manufacturing to guide electrical currents through the PCB to the components that run the electronics and computers associated with technology. Today PCBs are found in every electronic device and computer on the face of the planet.

Memory Cards - Portable Conveniance

2009-09-17T04:07:00.001-07:00

Memory cards are at the height of portable convenience for everybody needing to transfer information from one point to another. Anybody living in the digital age of the 21st century knows that convenience is one of the highest priorities. Whether you are using a digital camera, playing an in depth video game, or ensuring the safety of work equipment, having a high quality, portable, and dependable way to save your information will assist you in accomplishing your goal. These cards come with an amazing array of choices regarding the amount of data that can be stored whilst using them.

While storing information on your PC is a smart way to go, there is forever a horrible probability of something happening to that computer. No one ever wants to consider that something like this may possibly happen to them, but in this day and age of virus scares, power surges, and theft, a computer is never your most secure option. Using a memory card to save any valuable information on is a much more reliable way of ensuring you have that information at your fingertips when you need it most. This is becoming increasingly important as our society becomes more and more technologically based. Whether used for work or personal purposes, keeping your information safe is always a priority.

In addition to controlling the safety of your information, convenience and portability are also high on the list of priorities in our society. Whilst traveling for business, you can by no means be sure what you are risking by plugging into the broadband at your hotel. Even using an additional company's broadband or wireless access can cause problems if they are not as secure as they ought to be. If you are not using memory cards to look after your information, every time you log on to an internet connection you are taking the risk of losing your crucial data.

Electronic Lockers - A Short History of Lockers

2009-09-17T04:06:00.002-07:00

A brief history of Electronic Lockers: Lockers were initially invented to serve the purpose of protecting valuables from fire, theft, insects and destructive chemicals. They are usually made of fireproof and durable materials like steel coated with powder to prevent corrosion. Through the years, they evolved together with the technology available to men. Common lockers were initially made of a steel body with padlock and key. Today, there are varieties to choose from, whether for industrial or for household use - electronic lockers and safes, wardrobe lockers, floor lockers, touch screen safety lockers, digital electronic safety lockers, wall mounting lockers, double door safe, dual lock system, biometric locking system, twin safety lockers and more. Although there are dozens of ways to call them, we can categorize them in the way they keep our things safe: how they are locked - electronically, mechanically, or both.

Locking Systems:

Electronic Locking system: This kind of locker and safe system uses the latest technology like digital code number keys, biometric keys, electronic card keys or the combination of two or more electronic keys. These are the most convenient and user-friendly lockers, which are commonly found in public places like parks, airports, schools, factories, universities and more.

Mechanical Locking system: The pioneers of the locker industry first used metal padlock-and-key system, the most rudimentary way of keeping our things safe in the modern times. This later on evolved in a number combination lock system where the owner has to contend to one lock-combination made by the manufacturer.

Dual Locking System: Dual locking system is a combination or a hybrid of both mechanical and electronic locks. It employs digital lock combination, a biometric identification, an electronic key card paired with mechanical combination and/or a master key. This locking system may be the safest of the three.

Protect Your Domain From Being Black-listed

2009-09-17T04:06:00.001-07:00

What is Black-list? A Black-list is database of known Domains and IP addresses used by or for Spammers. A lot of Carriers/ISPs subscribe to these databases to spot and control SPAM from going across their links. Certain organizations will publish their Black-lists and allow you to search them to find out if you have been listed. Once you have been listed on one or two Black-lists, it will not be long before you are listed on all of the databases. Then you will not be able to send email to your customers or clients as they will be rejected due to Black-listing. How much time and money will your company lose due to this?

There are numerous reasons why you might end up on a Black-list, a PC in your office might have been infected with a virus that sent out SPAM, a Marketing Email might have been falsely identified as SPAM or your email server might be open for relaying SPAM. Any number of these can end with being listed. What do you do now?

Well, find the reason for the Black-listing for one. If it was an infected PC, then clean the virus off the computer and contact the Black-lists to be de-listed. Although, you have bigger issues than that because an infected PC could email out to the internet, which means that you have port 25 open to all traffic on your router or firewall. It should only be open for a specific device, your email server. If it was a Marketing Email, contact the Black-lists to be de-listed and check to see if you are Can-Spam compliant. Last but not least, the Open Relay on the email server should be disabled. There are several sites out there on the Net that will test your email server to see if it is Open to Relay. Take the necessary steps to secure the email server.

Other items you might want to consider keeping this from happening again. An Email Security product will definitely help you from being Black-listed.

From personal experience I would highly recommend IronPort. Since I have implemented this product, no more Black-listings, SPAM, or Virus emails have gotten through. IronPort is not the only product out on the market today; friends have recommended Barracuda products as well. Either way, you are protected.

The Number One Way to Update Drivers Automatically

2009-09-10T03:46:00.003-07:00

There is only one way to update anything automatically, and that is by getting an automated update tool. Since drivers need to be updated, you might as well get a software that will do it for you regularly - without having to bother you. Plus, you can continue working even as it works in the background.

You may have been told that Windows has an update wizard feature, and this is certainly true. What you may not have been told is that not all updates are available in this Windows wizard. This is because to be listed on the Windows update wizard, you need to get certified by Windows.

You know, not everyone is on that list, and your drivers may or may not be on the list. If not, then you have the option of manually searching for the update on the internet, buy a device that is compatible with the Windows wizard (really?), or spend a few bucks on an automated update tool.

You can find quite a number of driver update tools on the internet, but to make your search a little easier, here are several of the top driver update tools you can choose from: Driver Cure, Driver Genius, or Driver Detective.

Of these 3, which are quite similar in design and features, the one you pick should also be capable of being updated as well. This means that if you updated your driver this week, it could have a better version in a couple of weeks. This also means that your update driver software should be on top of its game by having the latest updates for you.

Cornering the Problems of a Slow Computer With a Registry Fix

2009-09-10T03:46:00.001-07:00

It's annoying. It's like a "once upon a time, my computer was the best" kind of situation, and you were quite proud to boast about its performance. However, suddenly, your PC seems to be working against you, or has something against you, and it's giving you problems. You may not even know what exactly you are doing to cause the poor speed.

Here's a hint. If you are fully protected against virus, spyware, and the like, and your hard drive has barely touched 50% capacity, then the problem will undoubtedly lie in your registry.

The registry is a part of all Windows-based operating systems that contains all your system and operational files. Without a registry, you will not even be able to boot up, much more use your computer.

It is not really broken, but it does need attention because it has limited space, and you have used up most of it. Technically, the registry fix will clean up your registry from errors or invalid keys. You can do this manually, but it's very risky. One wrong deletion, and you could end up with the need to completely re-format everything.

No, the best way is to get the experts to help you out. These experts have created software to go in, scan your PC's registry, look for the problem area, and make recommendations. You won't ever have to suffer from a loss of power (or power trip) because a registry cleaner will boost your PC's performance by a huge margin.

Computer Memory - How Much Do You Need?

2009-08-26T09:11:00.001-07:00

In life, it is often said that "you can never have too much of a good thing." Apparently, this is not so when it comes to RAM (Random Access Memory - also referred to as simply "memory" or storage) for your laptop or computer! No need to spend money on extra RAM that your system cannot utilize. (You can easily check the specifications of the system you are considering by asking how much memory is already installed, and what the maximum memory capacity is for the system.) But how can you be certain you have enough computer memory not only for your current needs, but for what your future needs may be, too? Let's start at the beginning...how much computer memory do you need?"

When buying a computer or laptop, the available memory on that system should be a primary consideration, because the more you do, the more memory you need! The applications you use dictate how much memory you need for the best possible performance, the smoothest graphics and the speediest downloads. RAM is used every time you open an application, download, play a game or video - even turning on your computer requires RAM.

Peripherals such as webcams, digital cameras, DVD players and USB hard drives require more RAM. These requirements, coupled with complicated web pages and PC-based video games may surprise you in that you have significantly less RAM than you thought. Therefore, buy the most RAM you can afford; more RAM makes for a speedier computer. Today, available PC systems range from 512MB (which is the bare minimum) to 4GB of memory.

If you already have a computer and are considering a memory upgrade, review the manuals that came with your computer or motherboard. Included in the documentation are the specifications for the memory supported. This is important because it will list exactly the type, size and number of memory modules that are supported. (Most retailers and/or manufacturers have this information, too.)

Buy as few modules as possible for the amount of memory you want to install; this will aid in future system upgrades. (For example, if you have 3 memory slots on your computer, one of which has a 1GB module in it, it is smarter to buy another 1GB module to get to 2GB of total memory verses purchasing two 512MB modules.)

To give you some idea of RAM requirements, according to a 2009 pcstats.com article, Windows Vista Basic requires a minimum of 512MB, though they advise that realistically, that number should be doubled. In fact, the article states that "Vista will function with 512MB system RAM, but the ride is a rough one!" While Microsoft recommends Vista computers ship with 1GB memory, 2GB of RAM is generally considered the best option for Windows Vista.

The easiest ways to boost performance for any PC is to add memory (RAM) to the system. Before purchasing that memory upgrade, however, remember to verify what type of memory your computer uses, the memory module sizes and what already exists in the system. If you are buying a new system, look for the maximum RAM available.

5 Benefits of Using Inkjet Remanufactured Ink Cartridges

2009-08-26T09:10:00.000-07:00

Many consumers already know that Inkjet ink cartridges are costly and many times the price of the printer is considerably low because the price of the original cartridges is high. What many people do not know is that remanufactured cartridges have made huge step forward in recent years and are now an excellent alternative to the original ink cartridge which came with the printer.

It's true that in the past, the quality of remanufactured ink cartridges and toner remanufactured cartridges was not always up to the standard of the originals, however continuous testing by many brands of remanufactured inkjet and toner cartridges together with the support reused products are getting have ensured that consumers get the best quality ink and toner at a substantial discounted price when compared to the original part.

There are 5 main benefits of using Inkjet remanufactured cartridges:

1.Their price is considerably lower than the price of the original product. Due to the state of the economy the savings which are made by buying an alternative product means consumers have more disposable funds to spent elsewhere.

2. Most re-man ink cartridges are now coming with a 30 day money back guarantee making the decision to buy remanufactured even easier. Because the product have improved dramatically, money back guarantee is offered by many sellers.

3. They are of the same quality as the original and in times even better.

4. Some brands of reman ink cartridges will print the same and at times more pages than the original ink cartridges.

5. By using remanufactured ink cartridges more consumable items are going back into use, thus lowering waste and improving the environment. Many manufactures are seeing to it that the entire process from cleaning the cartridges to shipping them is as environmentally friendly as possible.

Today you will find that low priced remanufactured cartridges are available for all the major brands including HP (Hewlett Packard), some Canon printers and Lexmark. By understanding the benefits of using remanufactured ink cartridges the decision to buy should be easier than ever.

Is Your Company Using Your Most Powerful Tool - High Speed Internet Access?

2009-08-23T03:31:00.004-07:00

In the last ten years, the internet has drastically changed the way we do business. Twenty years ago, business owners and employees depended on the phones, faxes (if you had one), postal and package delivery services. Accounts were received and paid through credit machines and checks.

Now, it can all be done over high speed internet access. No waiting for callbacks. No waiting for information. Well, there still are humans on both ends, mostly, so there's still a little waiting. But, not much. When you need some information and you can wait a couple hours, you just e-mail the person who has the information.

Meetings that used to take people flying hundreds and thousands of miles can be done online, too. The virtual meeting or conference call can be held wherever people are, by phone call over the internet, by desktop meetings, and by internet camera call so everyone can not only hear everyone else, but can also see them on their monitor.

Services and products can be bought and sold online. You still have to wait for the service to be complete, or the product shipped to you, but you don't have to go to a store, or several stores, or make a load of phone calls to find out if services will be what you need.

Because of this drastic change to the way we do business, the need to have high speed internet access available with platforms that can help you is more important than ever. A company that isn't online these days will miss out in a big way.

Branded Memory Sticks Replace the Chainsaw

2009-08-23T03:31:00.003-07:00

Most companies, irrespective of their size, will either exhibit at or attend one or two trade shows, conferences or business forums each year. In some cases companies become serial exhibitors or serial attendees of such events.

For some attendees part of the attraction is to simply gather as many "freebies" as they can from the exhibitors but for the vast majority their attendance has a serious business justification. Attendance or participation is typically linked to building industry and competitor knowledge, networking or buying and selling.

Historically it was impossible to attend these events without either printing the equivalent of a rainforest's worth of brochures and sales literature. Likewise many attendees' arms get extended during their day as they accumulate the said printed material.

Another casualty of this frenetic conference and exhibition giving and attending is the humble tree that surrenders itself to the chainsaw to provide the raw material for the brochures and sales collateral But things are changing, albeit slowly.

Today more and more companies recognise the environmental, production, storage and distribution costs of such actives and are now switching to USB Memory sticks. The humble USB memory stick can be pre-loaded with electronic copies of sales brochures, price lists, presentation slides, videos, links to web sites etc. In fact all of your businesses sales collateral can be pre-loaded onto a single tiny USB Memory stick.

As well as replacing a huge amount of expensive and heavy paper the USB memory stick can of course be branded to carry a company logo or brand.

You can take USB memory sticks one stage further and get a fully customised memory stick produced in the shape of your company logo or perhaps a specific product, examples include USB trucks, guitars, fruit, light bulbs, aeroplanes, mobile phones etc. In fact pretty much anything can be manufactured with a USB connector on the end. These customised versions make a real impact and are ideal when there is a particular product to launch or promote.

Whether a customised memory stick or more conventional branded USB memory stick is used the benefits to all are obvious. With the fall in the price of branded and customised memory sticks the costs when compared against printed collateral also stack up. So putting aside the environmental arguments branded USB memory sticks make commercial sense hence why their use is becoming more popular.

Study on Computing in the Cloud

2009-08-23T03:31:00.001-07:00

Introduction:

In traditional network diagram, the cloud always represented a fairly static view of an intermediary virtual area on the Internet. It basically had no real function other than passing data from one point to the other between servers on the Internet and client where we cloud setup our applications to run

The cloud computing model changes this slightly. Instead of providing just a medium for messages to pass through between clients and severs, it tries to provide a number of services within the Internet "cloud" itself. These services can range from storage, computation, applications and even complete operating systems. All available as a service on the Internet which you can go ahead and use directly. The "Software_as_a_Servic" or SaaS concept is one of the major diving forces of cloud computing along with other concepts such as Web2.0, the web browser and mobile applications.

Objective of the Study:

1. Purpose of the study is to virtualization of the environment.
2. Less expensive in context to server maintenance.
3. According to demand provide the application services and others.

Methodology:

In this paper relevant literature, information and data have been used from the published books, magazines like PCQuest, DeveloperIQ, Computer Today, InformationWeek, relevant web sites etc.

Text:

We can't turn around these days without hearing "Cloud Computing". So what is cloud computing? Is it the same old stuff with a new wrapper? Cloud computing is a development model leveraged by IT to reduce infrastructure costs and/or address capacity/scalability concerns. It is the infrastructure and model of deployment. Cloud computing is about how an application or service is deployed and delivered. Cloud computing is a deployment model leveraging on demand computing to scale and serve applications through a shared resource model.

Are there different types of clouds? Yes, there are. There are public clouds like Amazon and Microsoft, and there are going to be private clouds as well. Because cloud computing is concerned with how applications and infrastructure resources are provisioned and delivered, location is really irrelevant in determining whether an architecture is or is not a cloud.

There is also differentiation between cloud models; some are based heavily in virtualization and we deploy applications by pushing a virtual image of our applications and its environment into the cloud using web services. Other provides platforms upon which we develop the application and which are then packaged up and provisioned on demand through the provider's custom environment.

Scalability is an issue in all kinds of software development and computing. Dose this include cloud computing? Absolutely, there are basically two different kind of scalability such as horizontal and vertical. Horizontal scalability means the application can serve many concurrent users, which is easy and one of the benefits of cloud computing. That's the job of load balancing and application delivery solutions and should be taken care of by the cloud. Then there is vertical scalability, which means that the application continues to perform consistently as load increases, and that is just note something the cloud provides.

What about security when it comes to cloud computing? Secure cording is an absolute requirement for cloud computing, as is a wide variety of application and network layer security in the cloud computing infrastructure. Secure coding practice are the best way to prevent exploits of application logic and unauthorized access while firewalls, web application firewalls, network(IP) and transport layer(TCP) security solutions are all necessary to prevent as many attacks as possible from penetrating the outer rim of the cloud. Secure remote access to applications and services in the cloud, allowing for more sensitive applications to execute in the cloud and be accessed from anywhere while protecting the communication.

Cloud computing offers virtually unlimited, on demand computing resources. Our applications now live in a new platform- a computing cloud. In the cloud, our applications take advantages of the seemingly limitless processor cycles, memory storage, and network bandwidth along with extensive software capabilities. Our applications only pay for what they use. Cloud computing offers a range of application services that from a new platform-an Internet operating system suitable for cost effective, dynamic, and Internet-scale solutions. An Internet operating system offers the scale and services required to meet the requirements of a dynamic, global, software application.

In an infrastructure cloud environment, the situation is radically different. Our data and processing power can get moved at win from location to location, possibly with varying levels of physical access controls. The underlying virtualization system of some infrastructure cloud providers may not yet be capable of providing strong assurances that virtual machines sharing a hyper visior are in fact separated and immune from attack. Cloud providers-in particular, the infrastructure variety-tend to be opaque computing services offering little visibility into their underlying architectures and technologies.

Cloud computing is the natural evolution of the application service provider (ASP) from the late nineties and software as a service (SaaS) strategies from more recent year. Vendors that provide cloud computing services supply the data centers required to host virtualized environments for their customers. Business no longer need the same capital expenditure to up and running and they can buy additional cloud computing resources on demand to meet the requirements of increased server load or peak periods in their business.

Getting into the cloud:

Currently we can create cloud applications through two major implementations:

1- Amazon
2- Google

Amazon:

Amazon has a number of cloud offering. The Amazon EC2 (Elastic Compute Cloud) is an offering that allows users to request "virtual machines" in the cloud. Once the request is met, the user can "provision" these virtual cloud servers to run any software they want. This is completely dynamic in the sense that the user has control over how many virtual instances he wants to provision and run at a particular point in time. The servers can run anything from OpenSolaris, Linux to Windows Server 2003.

Other services that Amazon has include S3 (Simple storage service)- a service that lets users or applications use unlimited storage for their files and SimpleDB a distributed database system that can be used in conjunction with S3 and EC2. All of these services are available through programming models to enable end users the ability to use them in their own applications as well.

Google:

Google provides two different sets of services in the cloud computing world. the first is the famous Google Apps- a combination of services that users can use as part of their own domain to enable common functionality. The different parts of the Google network- Gmail, Calendar, Talk, Sites and Docs- are combined into a packaged offering that users can subscribe to in an enterprise. This enables users to have their organization's data stored up in Google's "cloud" and make it accessible almost anywhere.

The other service that Google offers is the App engine. This is an online application frame work where users can host their own applications. However, the Google App Engine only supports a limited version of python as their programming frame work. It also has a database like construct with an SQL like language to be able to use to program applications.

Conclusion:

There are many other companies in this playing field as well-IBM, HP, Sales Force-to name just a few, who are heavily investing in this model of computing. Since cloud computing reduces the infrastructure requirements and budgets that an enterprise needs to host their applications or data, this model seems to be getting more popular. One doesn't need to worry about purchasing and provisioning hardware and software integrating it into the network and other headaches. Simply request the service or update we want and it gets done for us transparently. Cloud computing can help us or at least manage our infrastructure costs better and allow availability of our application and data over the Internet. However, one must be able to ensure that data is available anytime one needs it and having good software and a seamless connectivity to the service is essential in this regard.

Here are 3 Steps which can help you solve and avoid blue screen error from pestering your system. Just follow these tips and your computer will be error-free.

1. Inspect your computer's registry
All the vital data in your computer are saved in the Windows registry. The hardware, software programs installed are also registered here. But sadly, this registry entries can be corrupted and then make your system lose some important information required for the better performance of some programs or tasks.
When information went missing, the blue screen error develops and then freezes your computer. Most PC owners don't know how to repair some issues like this. On the other hand, the availability of the registry cleaner and repair software makes everything easy and manageable for the average users of computers because it is automated.

Plus, it is not hard to find, you can download it and some are even offered for free. That's a big savings for you since it's free and you'll no longer have to bring your computer to a technician as you can fix the problem yourself through the registry cleaner.

2. Spyware, adware, and virus scan
When you have already tried the first tip and it didn't solve the blue screen error, then this time, try running an adware, spyware, and virus scanner. You can also obtain this software for free in the internet. The scanning here can take a while longer compared to a scan by registry cleaner because it scan your hard drive thoroughly.

Blue screen errors are not typically caused by viruses, but it's possible. These sorts of scans are recommended to be done once a week for better results.

3. Deletion of a particular program and re-installation
Finally, if the first and second steps are not effective and haven't solved the Windows XP blue screen error, then a more drastic measures are needed.

Firstly, ensure that your windows restore function is active and you have an existing restore point set. After doing this, single out the running program/s where the blue screen usually appear. Delete and then re-install that program through your control panel.

Take note, prior to the deletion and re-installation procedure, make sure that you have the original CD or downloaded files of the program concerned. Otherwise, you will not be able to re-install the program that you have already deleted.

This simple method should repair Windows XP blue screen error permanently. Definitely, a trip to the computer repair shop is not an option if you can try and fix your computer by yourself. And this is what this article intends to do, to help you determine and find solution to some problems in your computer system.

Remembering the Old Days and Internet Access

2009-08-14T22:56:00.003-07:00

Do you remember the days when internet access was hard to come up with or one out of every ten homes had internet access? Or being at school and having to go to the encyclopedia in the library to get the information, because there wasn't such thing as internet? Then there was the thing that if someone had internet it was dial up and it was slow as molasses. Then you would go to the office and it was a little faster.

It was normal to wait for awhile to download any kind of website. Now if you are a teenager or in your early twenties, you might not remember these days, but for anyone older than that you can remember these times.
Not only do we remember those times, but then the option of getting the internet was that it had to be hooked up to a phone line. We couldn't pick up our laptops and go from location to location and still have internet at our fingertips.

Now, if a website doesn't pull up in a split second we are wondering what the problem is. We want everything much quicker and it is all at the access of our fingertips. That is the luxury of high speed internet access. We are able to save so much time and money due to the speed of high speed internet. We are able to be more profitable and efficient in what we are doing. Now the opportunities are endless and we can all turn to the internet for our information and our businesses. We can communicate with our friends and family through blogs and social networks. What a blessing high speed internet access is in our lives.

Very small businesses with 4 or less employees can get by without even using Quickbooks, but once you are larger than that it becomes more and more effective to use Quickbooks. One of the best ways to maximize Quickbooks is to write all of your checks from Quickbooks.

All you need is Quickbooks pro 2007 or newer or Quickbooks simple start which is free. Excel, Open Office Calc, or the free Google docs spreadsheet. Also computer checks which you can order from a variety of different companies.

The trick if you are going to maximize quick books is to write all of your checks using Quickbooks otherwise you will have double the work. Hand writing checks is a very tedious and time consuming process. To set up your vendors just click on vendor center. Then click on new vendor and enter vendor name and then enter opening balance and enter the date in the as of date field or just use the calendar option to select date. Now enter all address info then click on additional info tab and enter account number and select type then terms if any and tax ID then click next to enter the next vendor.

To write checks from Quickbooks just click the home button and go to the Banking area to the right and click on write checks. Select Bank account to write checks from then begin typing the name of the vendor, usually just one letter is all that is needed as all vendors that begin with that letter will appear so just select the one you want. Enter the amount then select date and select check number from the first computer check that you will be using. Hit tab after entering amount and it will automatically enter the written number onto the check. The check will automatically go into the correct expense account if you have entered your vendor information correctly. Now click to be printed to print later or print as you go if you like. Then click save and new to write the next check or if you are done you can select save and close. It is usually easier to enter all of your vendor checks before printing them.

To print checks from Quickbooks just click the home button and go to the Banking area to the right and click on print checks. Select Bank account to print checks from. At this time all of the checks that you created should show up so you can now print or deselect any that you don't want to print. Make sure to enter the number of the first check to print. Then make sure to count out the checks to be placed in the printer then place them in the printer making sure to place them either face up or face down per you printer instructions and also make sure you know what is top and what is bottom. then click ok and select the type of check to print. For vendors it will not usually be the voucher style but the standard form. Don't worry if it does not print correctly you can reprint them.

For tracking sales commissions it is usually easier to use a spreadsheet especially if you have multiple sales commissions per sale. You can download Openoffice for free or you can use the Google documents spreadsheet for free. The advantage of the Google spreadsheet is that you can share it with particular individuals and don't have to worry about e-mailing or losing files you have saved type of problems. Also multiple people can be entering information on the same spreadsheet. Happy Bookkeeping!

Why QWERTY is Invented

2009-08-14T22:55:00.000-07:00

The QWERTY keyboard is invented in the early 1870's. The man behind this great invention is Christopher Sholes, who was an editor and also a printer. Through trial and error he perfected his invention and overall it has taken him six years in order to finally create the perfect type writer. In 1878, a patent is created for a type writer. It was a drawing of a type writer that specifies how the letters and alphabets are located.

These days there are way too many alternatives to the excellent QWERTY. We have Maltron keyboard, Dvorak Simplified Keyboard and many more. These alternatives might not be better while some of them might be similar in many ways.

QWERTY is used widely for mobile phones these days. This is a very good act considering the fact that most mobile phones act as a mini laptop as well. With features such as emails and instant messages, we could use a QWERTY keyboard to speed things up. Imagine having to type using the conventional keypads, which would take up more time when composing emails or instant messages.

Unlike SMS, instant messages such as Yahoo Messenger is much easier to use with QWERTY. Besides emails, we would also be using QWERTY in mobile browsing. Imagine browsing different blogs or websites and having to type slowly when we are searching for something important. With this cool invention, we can speed everything. It is all about convenience. It would be much better to have QWERTY keypads on mobile phones that offer emails and instant messaging features.

The invention of QWERTY is indeed the most important for laptops, computers and mobile phones. Thanks to this great invention, we can surf the internet much better on mobile phones. No matter where you are, QWERTY is part of our life. Therefore, why not learn to use it and love it?

Recycling Apple Laptop Batteries

2009-08-08T07:33:00.001-07:00

If you wish to play a role in helping to have a positive impact on the world in which we live, recycling is one of the best ways for you to do so. Recycling is vital to both the natural environment and to humans. We must act swiftly, as the amount of waste we create is increasing all the time. Landfills cannot keep up and when people throw away hazardous material in with their regular trash, this can cause major problems. Another issue is that large amounts of energy is being used to manufacture new items, when for a fraction of the energy, older items can be used to create new ones.

It may not seem as if one person can make a difference, however if you think about the millions of people who at some point will be disposing of their Apple laptop batteries and batteries from other types of computers, the amount of potential hazardous waste is astonishing.

The amount of trash that humans create is always increasing. There are several reasons for this. As people buy more products, they ultimately have more to throw away. As the population increases, there are more humans creating waste. New packaging, which may save manufacturers some money, are not environmentally friendly which means that they are not biodegradable. While the messages of going green and the very importance of recycling are being heard now by more people than ever, it is still very important to remember that anyone with Apple laptops should know about programs to help customers very easily lend a hand in recycling Apple laptop batteries.

The Apple corporation strongly encourages customers to recycle their Apple laptop batteries. They clearly state that Li-Ion, NiCad, NiMH batteries are known to be hazardous to the environment and should not be thrown away with your trash. For this reason, they have are part of the Rechargeable Battery Recycling Corporation, which has a website to let you know what to do. Basically, thousands of sites have been set up nationwide to accept old batteries. These are in convenient locations, such as food stores and malls. Once collected, they are shipped off to facilities which will take those old batteries and put them to good use.

MP3 Players - Why the Apple iPod is King

2009-08-08T07:32:00.001-07:00

The first mp3 Player was introduced in 1998 by Eiger Labs and was called the MPMan. It had a storage capacity of 32MB (about 10-20 songs) and sold for $69. Now it is not uncommon to find an mp3 player with 120GB of storage capacity (up to 30,000 songs) for $249. However, long gone are the days of using an mp3 player as, well, an mp3 player. Most mp3 players now serve as the "swiss-army knife" of electronics. They can play music, show photos, play videos and movies, connect to the internet, check email, and serve as a personal arcade.

When the words "mp3 player" are uttered, the first thought that comes into people's mind is "iPod". Why is this the case when there are several mp3 player manufacturers out there (Sony, Samsung and Creative Technologies to name a few)? Is it the creative television ads that seem to bombard us at least twice during a 30-minute episode of "The Office"? Is it the fact that these players come in several different colors to fit our mood? Is it the slick navigation and the ease of use? Or is it due to the fact that inside each of us, we are rooting for Apple, the underdog, who has pitted itself against the mighty Microsoft Corporation?

Whatever the reason, the fact is Apple has creative geniuses behind the marketing and development of these ever-changing devices. Each ad we see on TV gives us a sense that we have to have one of these devices... to be hip, to be cool, to actually have fun in life. Then you take a look at the actual devices themselves. They come in ultra small (iPod shuffle), ultra colorful (iPod nano) and ultra slick (iPod touch). The varying types of iPods makes it easy to please anyone from the occasional music listener with small pockets, to the frequent flyer who needs a device that can keep them occupied with music, movies and games during a three hour flight. There is literally an iPod for every lifestyle.

Don't forget the ease of use, the simple iTunes integration and the continual updates and new applications that ensure you are getting the most from your iPod. The realization is that Apple is leading the way in mp3 player development while all the other mp3 player manufacturers just seem to be a step behind. With prices ranging from $79 to $229, every budget is considered.

Not only are consumers jumping on the iPod bandwagon. Many companies have focused on developing iPod accessories for each model ranging from plug-and-play stereo systems, to sports bands, to iPod sleeves. These iPod accessories are becoming as hot a commodity as the iPod itself. Now the question isn't "which brand of mp3 player should I get?" but "what accessory can I get for my iPod?"

With the iPod being such a hot commodity, iPods and iPod accessories are readily available for purchase with more online stores showing up every day and with the iPods and iPod accessories being sold at "big box" stores like Walmart and Target.

As more people invest in iPods, there is an increasing demand for iPod repair services. For a few of the inexpensive iPod models (iPod shuffle for example), it doesn't make much sense to pay for iPod repair service. However, for the more expensive models, iPod repair can be a substantially cheaper alternative to buying a new iPod altogether.

The Benefits of Computer Equipment Rental For Business

2009-08-03T06:46:00.003-07:00

Many of us are hesitant to borrow anything unless it is utterly necessary to do so. Personally, I look at the act of borrowing as immature and selfish. I mean, why would you go out of your way to use or waste someone else's resources, when there's obviously plenty of ways you can get what you want for yourself? Doesn't it seem like you're being unfair to the person you are borrowing from in the process? Well, to a certain degree. But I have come to the realization that borrowing has a whole side to it that creates benefits for both parties involved. Without assuming too much, this probably is the principle behind the unstoppable growth of PC rental solutions providers all around the world.

We have got to admit it. We are a civilization run by technology. Although this may not be a characteristic we can boast of for our generation, our reliance on automated thinking machines like computers have made our lives superbly comfortable over the past decades. Computers are fast becoming indispensable tools in progress. And as such, it is easy to understand the undying demand for this ingenious invention. But to some extent, it all becomes too impractical. Computer and audio visual equipments are expensive. To patronize them persistently can cost you a fortune. Considering that technology advances quite rapidly, keeping yourself updated with the latest gadgets may not be as feasible as you think. This is where borrowing, or in another word, leasing, produces a hole of opportunity. A PC rental solutions provider is the entity that keeps itself abreast with technology and then produces income by allowing others to do the same, through rental. This procedure has now become quite handy in the realm of commerce.

Computers are essential in the commencement and completion of processes that are involved in business. Simple tasks such as encoding, bookkeeping, and research, to name a few, become more organized and simplified with computers. But apart from these, there are more complicated tasks that require the use of extensive amounts and more advanced computer products, either for shortened or prolonged periods of time. An IT solutions provider can address these problems effectively while saving the company from massive expenditures. This is a major benefit provided by computer equipment rental. Now, companies need not buy in a rush when they desire to use something. They can just rent it. And in line with that, a computer rental solutions provider can also supply equipments specifically matching a company's requirements for a specific program or event, without the hassle of installation and set-up.

This leads to less time wastage on complicated technological workload, and more time spent on productivity, with more manpower involved in the work process. Can you smell B-I-G-R-E-V-E-N-U-E? I guess so. These are four more benefits that computer rentals give businesses. In addition, PC technical support and product exchanges are other service extensions that PC rental solution providers furnish their clients. Yet again, another money-saving benefit for the business industry. It's astounding how the possibilities go on and on. In fact, these rental shops also supply personal and/or network laser printer rental, LCD or plasma display rental, photocopier and projector rentals, and even servers; all for the convenience of a company. Depending on the availability, they are even selling computer ex-rental equipment in response to a customer's preference. Talk about saving money! Every aspect of computer equipment rental boils down to saving money and making money. And isn't that what all businesses want? Indeed, borrowing is an innovative and genuinely advantageous enterprise for all companies wishing to catapult their business to success. And it is all thanks to PC rental solution providers, like TR Vidcom, that we owe our business' resiliency against the tides of change and economic struggle.

The Network Time Protocol - Used in Computer Networks

2009-08-03T06:46:00.001-07:00

By description, this is a protocol designed for transfer of time around a computer network. It works through a hierarchy composed of several strata starting with Stratum 0 which provides the external source of time. Stratum 1 gets the accurate time from a hardware clock which can be got through GPS signals as they are the safest and most reliable. This is because of the many satellites that orbit the earth at any one time. The references are not limited to these as radio signals and broadcasts also provide a safe and relatively reliable source of time. The broadcasts vary with locations and are not as centralized as the GPS signals but they all provide related times, if not equal. Some common ones include MSF from the UK, JJY from Japan and WWVB from the USA.

Reliability being the main issue means that there is need for backup reference clocks in the unlikely event of a signal outage. These references provide the time with the same precision as the signals and are able to maintain a holdover for extended periods until the signals are regained. These backups are expensive however and the reasons for getting them should be more than the reasons for foregoing them. If you decide you need them to maintain the time then there are crystal oscillators that come at a good price.

NTP client software is usually provided with most OS. Linux has GNU public licence NTP client while Windows has Windows Time service. The advantage of having NTV servers is that is to make sure that the time-stamped transactions are carried out in the specified order. They are the missing link between network time distribution and the global time scale and should be an integral part of any company or organization.

AntiSpam Etc - Email Safeguards in a Nutshell

2009-08-03T06:40:00.000-07:00

There is no single product on the market, even at the high end, with a 100% perfect capability for intercepting every threat to your email. However, if you are willing to look beyond the ordinary, it is possible to get an extremely high level of protection for your email without excessive hassle or cost.

Initial Strategic Decisions

Your email strategies have implications for the vulnerability of your email. If you have ever suffered the embarrassment of apologizing to angry customers, colleagues and friends about a virus that spread to them through your email, you are concerned about more than your own computer. You also want to avoid letting anything misuse your email to spread itself.

Many people use server based email accounts and access their email only through a web browser. This is especially common for personal accounts and free email services. Some businesses do it too, hosting email on their own servers, so that traveling workers need not carry their own PC with them. PCs with a standard software configuration can then be rotated among the workers as needed. If you use server based email, a virus that relies upon an email address list on the PC to propagate itself cannot find any such list. It may infect your PC, but that type of infection cannot spread itself from your PC.

Many users prefer to run an email client on the PC so they can compose messages offline, download incoming messages, and keep message archives for offline reference. Hackers target the most popular email clients more often than other clients. As a result, simply choosing a less common email client can help you dodge some bullets.

Basic Protection

Even if you always leave your email on a server and get to it through a web browser, and even if the server attempts to block viruses, the bare minimum level of protection is antivirus software. Remember, just one infection is enough to give you a nasty headache. A few websites offer antivirus scans free of charge, but you are safer with antivirus software that runs on each PC, especially if you choose to download email to your PC. Antivirus software on your computer can not only scan for infections, it can screen incoming email to intercept infections before they become established.

When combined with a subscription for frequent online updates, this is a good first line of defense. It often comes in a bundle with a personal firewall program and software that blocks specific behavior from websites. If you have only "pocket money" to spend on email protection for each PC each year, this is probably what you will buy. To be safe, you will probably continue to use it even if you add heftier protection elsewhere. Symantec and McAfee sell two of the most widespread lines of software for this purpose, and issue security updates quickly as new malware appears in the Internet.

Add Spam Filtration

Shielding against viruses does not reduce the amount of spam. Published estimates say that up to 90% of email is spam. Wading through 100 messages to find 10 that are legitimate is a waste of time and capacity.
You can get antispam filters that run on your PC. Some email clients come with such a filter. It is likely to do a poor job of distinguishing spam from legitimate messages and may not allow tuning of its sensitivity. "Pocket money" can buy a more accurate filter, although it will still make a lot of incorrect decisions and its ability to "learn" greater accuracy is generally limited.

The next step up is a filter on your email server--the larger computer that initially receives email from the Internet and from which your email client downloads messages. If you are using email service provided by someone else, including one of the major free services, they are likely to run such a filter. Some hosting services offer a server based filter bundled into their hosting packages. They choose software priced so that with volume discounts, they can afford to cover the cost with part of their hosting fees. Alternatively, if you have your own email server, you can buy the antispam software of your choice. That gives you greater accuracy and better ability to tune the filtering.

Unfortunately, for spam filters up to this level of sophistication, the primary method used to detect spam can be defeated by a clever spammer. These filters look at contents of the subject line and body for each message, seeking words and phrases frequently found in spam. Have you ever wondered why a lot of spam contains an advertisement in a picture instead of text? It's easy to analyze text. It's hard for software to discern words embedded in a picture. Server based filters do more sophisticated analysis than PC based filters, but mistakes still occur.

These spam filters also check the sender against one or more commercial blacklists. In theory, blacklist providers know which domains have been sending spam. In practice, some blacklists are too easily tricked by "spoofed" headers in spam messages, or they blacklist the entire network location that sent the spam even if the IP address is shared by several unrelated domains. That causes some innocent domains to be blacklisted. Spam filters using the blacklist block delivery of legitimate messages from those domains.

One of my clients nearly lost an important customer because their server based antispam system routinely segregated his messages as spam. Even though they are using one of the leading enterprise class filters, for six months the customer was unable to get through. A more accurate solution is available, and it provides more than antispam and antivirus filtering.

Sophisticated Gateways

The next step upward is to subscribe to an email protection gateway. You can do this only if your email is on a domain where you manage the email server. To use a gateway, change the MX records for your domain to point to the gateway. This tells the Internet to send all your email to the gateway instead of to your email server. The gateway removes viruses, segregates spam into quarantine, then sends your server only the messages that it considers legitimate.

This goes beyond sending viruses and spam into quarantine. It reduces the email load your server has to handle, because quarantine is at the data center that provides the gateway instead of your equipment. One of the largest nationwide real estate firms in the USA, with about 40,000 email accounts, was planning to upgrade its computers and communication lines when it began using an email protection gateway. The gateway reduced the amount of traffic to its computers so much, the upgrade was no longer needed.

The best email gateways (not all of them, only the best) detect spam differently from other antispam filters. Instead of watching for key words or phrases used in previous spam, they analyze the attack patterns suffered by wide-open email accounts, tracing them back to specific source computer systems. Software analysis is augmented by round-the-clock human monitoring and analysis. This type of system can detect and begin responding to a new spam campaign within a few minutes, even when the campaign is executed through many hijacked PCs (a botnet). Accuracy is higher than when you run and perform frequent tuning on your own server based antispam system, and can easily be above 95% with hardly any tuning. Legitimate messages rarely get quarantined by the best of these systems, and little spam sneaks through.

The best gateways go a couple of steps beyond filtering, too. Some organizations need to prevent confidential or proprietary information from being sent to inappropriate recipients. Depending on the gateway you choose and the level of service you subscribe to, the service can filter outbound email in accordance with rules set by you. Without a gateway, this would need to occur separately on your email server.

Last and certainly not least, the gateway can provide disaster redundancy for your email. If your email server goes down, the gateway can store your email until the server is up again, then deliver all the email you would otherwise have lost. Some gateways allow you to access email through a web browser while your server is down, keeping you in business throughout even the worst disaster.

This type of system is used by the state college campus that hosts emergency responders after disasters in Port Arthur, Texas. They did not have it when a 2005 hurricane shut the town to all residents for about a month. Lack of communication made it hard to support for emergency workers, and especially hard to coordinate re-opening of the campus. The next time the town was shut for weeks by a hurricane, the campus relied on this system to help it keep going. Between emergencies, it has cut their incoming spam volume to a small trickle.

Cost Need Not Be High

That brings up the subject of cost. The college is able to afford the best available gateway service on its tight budget. Using the gateway allows the college to use less expensive arrangements for disaster recovery of its computer center, since email is always safe. Finally, the gateway helps the college avoid upgrades of its email capacity, since spam is almost completely eliminated from its incoming email.

Most small companies with just a few email accounts cannot afford a reasonably good server based system. Subscription to an email protection gateway for a company with five email accounts costs about as much as a monthly dinner out for one or two people at a modest restaurant. The more email accounts a business has, the lower the monthly cost per user. For businesses large enough to use their own server based system, a gateway is often either about the same price, or cheaper.

Although outbound filtering and email disaster redundancy may cost extra, at least one gateway includes those services at no extra charge and without binding customers into long term contracts. It is not just a highly reliable and scalable option, it is also surprisingly affordable and accessible for small organizations.

Free Trojan Virus Removal Tool Rated

2009-07-26T03:07:00.001-07:00

Trojan horse infections have always been a grave threat to computer systems and this is mostly because they were created for the main purpose of allowing third parties and hackers access to any system. These malicious infections which are a form of malware are commonly disguised or concealed as ordinary software on the web but rather infect a computer once downloaded and installed. What separates them from the virus or computer worm is that they do not make copies of themselves but as mentioned above they can give control to hackers who can harmfully modify or remove any content on your operating system. The best protection that one can use against these infections is either a paid or free Trojan virus removal tool which can be found on the web.

So how does this malicious content get into my system and how can I avoid this from happening? The only thing you can really do is be careful and cautious when you download freeware or any piece of software from the internet. Due to the fact that it can be almost impossible to know if a downloaded application is infectious you are advised to scan the program before you install it. Once the application has been installed it's already too late because the Trojan will already have unloaded various malicious scripts and other commands which will have infected other files and system features. Despite the presence of quality free Trojan virus removal tools on the internet a lot of people look for alternative methods which can instruct them how to remove these infections manually.

This can be hard if not impossible because of the great complex nature of these particular infections and that's why you are better off using security software. Unfortunately, finding and choosing a quality free Trojan virus removal tool for your personal computer system can be hard with so many in the market today. I have thoroughly tested many security tools available on the web and can confidently recommend Xoftspyse as the a leading security tool for all home computer users. With a comprehensive signature log that contains more than 280 000 definitions this easy to use program can detect many infections and remove them without hassle.

Data Loggers Are Reliable Workhorses

2009-07-26T03:06:00.001-07:00

Data loggers are stand alone devices, gathering and organizing a large amount of data over long spans of time. While they are sometimes part of a data acquisition system, data loggers can also be independently used for getting information reliably and unattended.

One aspect of the loggers is that they usually have a time stamping mechanism and can match data received to the time it was logged. If the logger has a built in real time clock, sometimes there is a bit of time drift however, the specifics of a logger's time drift are published and should be taken into consideration when choosing a machine.

Some equipment has very simple inputs and can only accept one or two channels of information. Other more sophisticated machines have intricate combinations of channels that involve multiple inputs for sensors as well as specific information sources. Modern versions can interact with external computer programs and are even able to automatically present collected information on a web page for remote collaboration between users. This ability to utilize data over the web has been very useful for the medical profession.

Because data loggers are stand alone machines, they need some sort of on board memory to store collected data. While earlier models used magnetic tape, punched paper tape, or even charts printed on reams of paper, modern loggers use RAM, flash memory or any one of the many memory options available currently.

Sometimes loggers are left for months in hostile environments to collect long term data. Usually battery power is used to keep them running, though some machines use solar power to assist the batteries. This limited power supply means that the loggers are very efficient in their power use, especially compared to a regular computer.

The operating system as well as the structural make up of these machines is extremely dependable. Since a lot of the time the loggers are operating without human supervision, they have to be completely reliable. The instruments are designed so that as long as they have power they will not fail to log data for any reason.

A data logger is dependable, accurate, and independent. These work horses of the scientific and medical professions have been assisting humankind for decades, and will continue to do so as long as we need reliable, well organized information.

RFID and the Future Asset Tracking

2009-07-14T22:43:00.004-07:00

Radio Frequency Identification (RFID) is a somewhat new technology that is used for automatic identification. Using this technology, data can be remotely retrieved through remote devices called RFID tags. Also known as transponders, RFID tags are chips which are attached or may be inserted into products, animals and even people. Radio waves are used to easily identify these chips and the information contained within. The transponders are normally made of silicone and are attached with antennas.

RFID tags are sometimes called transducers and are also known as proximity cards. They are available in three varieties: active tags, passive tags and semi-passive tags. Power is required for an active RFID system but no source is necessary for the passive type. Radio waves read information and instructions that are stored on RFID tag chips. These radio waves can read such information from up to 90 feet from where the chip is installed.
In the beginning RFID was used to identify dogs, cats and other pets as a means of permanent identification. It was said to be used in case the animal was lost or stolen. In today's world, RFID systems are used in almost every industry including but not limited to medicine, shipping and receiving, the automobile industry and libraries as well as being used in electronic devices and musical instruments.

The main purpose of RFID tags is to transfer data or any other information through particular mobile devices. These mobile devices are called chips and the RFID reader can read and process information according to the application.

RFID systems use an embedded in inexpensive tag that consists of a transponder containing a digital memory chip. Each tag has its own unique product code. The RFID transceiver will consist of an antenna, an interrogator as well as a decoder. When the transceiver remits a signal, better known as radio waves it activates the RFID tag. At this point information can be read or written into the memory chip. When a RFID tag makes its way through the electromagnetic field of its transceiver, it will detect the reader's activation signal. The point after the data has been read; the decoder can decode the data and pass it on to the host computer. The host computer will then process the data using Physical Markup Language (PML).

Telemetry: How Helpful is It?

2009-07-14T22:43:00.003-07:00

Science has revolutionized the globe. Nowadays we are seeing technologies everywhere and the world is getting more advanced day by day. To carry out along with the earth in the race of life we need to know about the latest processes. One of the greatest new method of science is telemetry that is discussed below.

Many readers of this article might be wondering what telemetry is. If you are looking to know basic information about telemetry than keep reading this article as it will certainly help you in understanding that what telemetry is and how we are using telemetry in promoting technology. There are so many features of telemetry that scientists are using for mankind. Some of the consequential features are outlined as under.

Telemetry is basically a latest technology that allows us to measure and to give an account of the knowledge through wire or by other means. Usually this technology is being used as wireless medium of data relocation through infrared, but it can also be used through telephone or radio etc. There are so many things that can be done through this technology some of them worth mentioning things are mentioned below.

This technology can be used in intensify law as the law enforcers can easily track out any wanted person through this and can also report the other police officers about any missing prisoner or person. Telemetry can also be used to seal out an area, through this law enforcers will easily come to know if anyone will enter in the prohibited area. Through telemetry, police force can easily draw attention to the stolen car regardless of the fact of where the car is. They can easily halt the engine of that car with the help of GSM tracking system which is actually based on Telemetry.

Telemetry has also revolutionized the medical field through many aspects. Usually telemetry is used in the ICUs and CCUs for serious patients so if the condition of patient gets worst nurses and doctors will get an alert intentionally through the telemetry system. By this way telemetry is helping a lot in the medical field and now it isn't necessary that a nurse should stay in the room of the patient.

Telemetry also plays a vital role in the agricultural field, because cultivating crops totally depends on the weather conditions and wireless weather stations plays a crucial role in developing good crops. These wireless weather stations are all of telemetry. Telemetry helps in measuring that what will be the weather conditions and also helps to inform others about the future conditions. In this way telemetry is useful and essential for raising of crops and livestock.

These are some features of telemetry through which we can easily ascertain how useful telemetry is. No doubt that telemetry is one of the best innovations by the innovators. Through the help of this technology we are now able to take precautionary measurements as we can easily predict by measuring the stipulation conditions and circumstances. Therefore, it is proved that telemetry is not less than a prayer said over someone for us all and we need is to use it in a right manner.

Computer Monitors

2009-07-14T22:43:00.001-07:00

Computers and the Internet have changed and continue to change the world. The computer is the vehicle that is introducing the world to technological advancements and medical and social achievements. Computer monitors are the windows of this new world and they continue to improve in quality and performance. The computer monitor of ten years ago is not the same visual display unit it is now, but it's still a piece of electrical equipment which can display a wide range of images from the video output of different computers, without creating a permanent record. The display device used to display images today is a thin film transistor liquid crystal display also known as TFT-LCD. The older monitors used a CRT or cathode ray tube.

Measuring computer monitors is a bit confusing. The measurement is based on the CRT television method, which was used when round picture tubes were popular. They were circular, so they only needed a diameter measurement to describe the tube size. When CRT tubes were manufactured as rectangles this method was still used, so the distance between two opposite corners is given as the screen size, even though it does not take into account the aspect ratios differences of monitors with the same diagonal size. The shape of a diagonal area decreases as it becomes less square, so the measurement system is a not accurate, in terms of square inches for monitors with the same diagonal size. Another issue with screen size is the size of the imaging element, which is distorted by media advertising campaigns. Viewable size is more important than measuring the image element size, which can be hidden behind the case's shroud.

Image technology continues to improve. TFT-LCDs are the most popular monitors, the old passive LCDs had a slow response time and the contrast was poor. They started to be replaced in the mid 1990s. Other types of visual displays include the Penetron and the Plasma Display along with the old CRT.

The LCD is light, compact and rugged and there is no geometric distortion, but it has a low contrast ratio, uneven back lighting and slow response times, which can cause ghosting. The Penetron Military Aircraft Display has high contrast ratios and is extremely sharp, although there are only four color displays. The Plasma also has high contrast ratios and a high speed response, excellent color and a low black level, but it has lower resolution on a large screen and there is a noticeable flicker when the display is viewed close range.

Today's computer monitors can display an infinite number of colors by continuously changing the intensities in the RBG color space, which is the red, green and blue analog video signals. New connectors are replacing both analog and digital signals with digital only video signals, which have integrated data and video connections. Other new features include multiple monitor capabilities, which can show the identical image called mirroring and extension monitoring, which shows different images but it does require extra hardware and software support. There's no doubt than computer monitors will continue to improve in quality as well as functionality. The touchscreen technology is opening the doors for another giant leap in the virtual display industry.

Monitor Options

2009-07-14T22:42:00.001-07:00

The computer has become an important communication tool for people around the world. The amount of hours spent looking at a computer monitor continues to increase as the Internet expands and more information is revealed. Whether the computer is used for business or pleasure, the monitor is the connection that brings all information to life and expands our awareness. Monitors are becoming more sophisticated. The old CRT tube monitors were good at the time, but the new TFT-LCD monitor technology is bringing the world into our homes with vibrant color and exquisite clarity. Good monitor images bring the mundane and boring aspects of work alive and make pleasure more pleasurable. There are several choices when it comes to monitors, so it's important to do some research and identify as many monitor options as possible, before deciding to make it part of your daily work or entertainment activities.

Screen size is one of the most important aspects of a monitor; the larger the screen the better, unless there is a space restriction of some kind. Widescreen monitors are the rage at the moment and 22" and 24" LCD models are in big demand. There are several manufacturers that have focused on providing the latest in monitor technology. Almost all of them make a good product, but since a monitor becomes a personal virtual display tool, it's a good idea to find a manufacturer that has a good reputation for making the type of monitor you need. Color and image quality are priorities, so pixel resolution and image display are extremely important. The TFT LCD technology is great for a small business or for the home environment. A TFT LCD monitor eliminates the radiation that plagues CRT monitors and they consume less power. The colors are more vibrant and they take up less space. The viewing area is larger and they can be integrated with other monitors and can display the same image or a different one, simultaneously.

The new widescreen LCD monitors can be integrated with webcams, so you can record videos or chat with friends or even hold business meetings. Other monitors have iPod docks and integrated speakers. A 27" screen is perfect for movie enthusiasts, video editing professionals and publishers. When a 27" screen is used on a daily basis, it's hard to work on a smaller screen. Some of the new digital monitors offer landscape pivot viewing, 178 degree viewing and a 1000:1 contrast ratio. Other models have USB hub features bundled into monitors, so games as well as music can be enjoyed. Navigating to adjust the brightness and the contrast is easy on some advanced monitors, they have a menu that enables the user to change settings and there is an auto-configuration button so the monitor can align and configure itself while using an analog VGA connection. There's also a feature that changes the signal input source. Some new monitors have 360 degree movement and can tilt forward and back 20 degrees and some even have height adjustments.

Monitors are changing as fast as computers and manufacturers will continue to add new features and functions that will improve the quality of our work and entertainment experiences.

Science and Technology For a Better Future

2009-05-22T07:47:00.002-07:00

One of the most often asked questions in the contemporary world is 'What is the meaning of science and technology?' Man is innovative in nature. The ability of man to create and change the shape of that which he has created is what sets him apart from other organisms. Science is the approach to study that emphasized the use of empirical evidence to come up with new ideas. As one of the branches of knowledge, it sets out to find out more on the nature of the physical world. Through practical analysis of phenomena, scientists have come up with solutions to many problems that have plagued mankind for many years.

The first step in scientific undertaking is coming up with a problem. Once a problem has been identified, there has to be dependent and independent variables that guide the researcher in formulating a hypothesis that will help him to come up with the most accurate results. A hypothesis is a tentative statement assumes that one of the two possible outcomes will happen. The researcher can choose to adopt any of the possible outcomes as his hypothesis. This is the foundation that led to the discovery of cures for many diseases that initially used to kill millions annually such as malaria.

The scientific approach to research is responsible for development of technology. Technology is the ability for man to make tasks easier to perform through a highly sets of scientific applications which build on interrelatedness of many basic principles. Machines are synonymously used with the concept of technology. Yet the contemporary use of the word presumes things like computers and mobile phones. It is true that technology these days must be viewed in terms of the changes brought into the existing communication systems through the computer. The electronics industry has grown a lot within a short span of time. Science has contributed largely to this since it is through continued research that new machines are being unveiled.

When trying to answer the question 'What is the meaning of science and technology?' we have to view science as the study of the natural world while technology has to be viewed as the study of how to manipulate the natural world in order to suit man. This relationship is best understood through Science and Technologies Studies (STS). Being a scientific discipline, this study highlights the relationship between these two areas of study and how they affect the cultural, scientific, political and social set-up of world's communities. The amount of information that is coming out of scientific enquiries is overwhelming. It is surprising how universities have succeeded in harmonizing the large body of research data that comes from research institutions fro around the world.

To differentiate between scientific enquiries from the artistic ones, there is need to look into the nature of truth. Science has no room for that which is taken to be true or false on the power of belief. This is the best way in which we can answer the question 'What is the meaning of science and technology?' There has to be a way of verifying the truth or falsity of any phenomenon. This is called the verification principle. There must be truth conditions which in practical terms are variables. If a statement cannot be proven to true or false, it is without sense and is not good for science and technology.

Technology and Advanced Systems

2009-05-22T07:47:00.001-07:00

The days of the past are nothing like what we have with us now. Thanks to bright minds from our history, from Albert Einstein to Thomas Edison with his gift of electricity, the world has taken a whole new shape and use of advanced systems and technology are slowly becoming an ordinary and accepted part of life.

The most advanced systems have been geared towards making man more social and this has seen the growth of the mobile phone from a simple calling device to a gadget with GPS capability. Its wireless capabilities have been one of the greatest gifts technology has to offer and it has become a necessity in the 21st century. This coupled with internet access has simplified life in a whole new way and one does not have to go to the office to conduct business. Not now that video conferences have taken over and sped up the rate of business transactions. Two people who are continents apart can meet up over the internet, trade or engage in some money making programs, all from the comfort of their homes.

Man's curiosity has exceeded expectations from the preceding centuries, and demand for more advanced systems and technology has risen. In matters of travel, getting from point A to B is no longer a matter worth losing sleep over. World class planes that offer Internet access to five star treatments and if the trend is anything to go by there is really no saying how far technology will take us. Speed has been an area of interest and this has seen the development of electric trains that to cars that besides making speeds close to those of sounds have been designed with built in maps to guide from one place to another.

In the pursuit to increase his knowledge on the functioning of body systems, man has employed advanced systems and technology to figure out, among others, the genetic composition of the human beings. From gene mapping to gene manipulating, the limits to how much technology can achieve have been few. Some genetic diseases have been treated and cloning has come into play in these more recent years. Along with these is nanotechnology, manipulating the atom at the molecular level. Thought an uphill task for the scientists, they are hoping to come up with, for instance lighter stronger metal that can replace the alloys in use today.

Merging of man and machine is not so far away as previously thought. This is with the development of a prototype eye that is part man and part machine, and that has signs of success. However all these come at a cost. The environment is on the suffering end for all these technology since most of them are not biodegradable. Source of power is yet another issue since natural resources like wind and sun are underexploited. These not withstanding however, the use of advanced systems and technology have revolutionalised our world and so much more is expected.

The Technological Education

2009-05-22T07:45:00.000-07:00

Technology is growing so fast that it becomes difficult to ignore it. Technology is being used in so many applications world wide and as the world becomes a global village due to technology, even students and teachers cannot ignore the its power. The history of using technology in the classroom has come a long way such that it is becoming the most convenient way to learn and teach.

Technological innovations such as the internet have become a major source of information to both teachers and students. There was a time when teachers and students had to go to libraries and other information centers if they wanted to get information on a certain topic which was very tedious and took a lot of time. Now they only have to surf the internet to get the information they want as fast as possible.

If you want to study for a certain course, it is not a must you go into a classroom in order to learn but you can do that through correspondence, thanks to technology. Many colleges are now offering opportunities to learn and receive degrees or diplomas online. There are also new forms of educational opportunities whereby you can receive a live lecture when you are in a different location via telecommunication links.

When handling your projects, you can still communicate with your supervisor who is away for one reason or the other. It is possible since you simply do a part of it and sent to the tutor via email so that he /she corrects it and sends it back in the same way. It is not a must that the two of you be on the same location.

Technology has also made it possible for students to improve their learning capabilities. Students have now been using computers and projectors to present their work in the classroom instead of using the usual blackboards to write on. This history of using technology in the classroom has made it possible for students to improve their technical skills and participation in the learning process. Students do their own research and present it in class and this helps to share ideas.

Technology has also made sure those students who take up technology oriented courses have better learning facilities for their professional experiences. Schools can equip themselves with the necessary facilities because they are now available and affordable. This has helped to produce better individuals into the various industries.

Teachers teaching using computers are more interesting because this creates a fun way of learning for the student as well as the teacher. Technology is more appropriate for teaching subjects that are more practical than theoretical for better understanding.

Computer Clean Up - Everything You Need to Know

2009-05-09T08:17:00.003-07:00

Looking to clean up your computer? Follow this computer clean up guide and you'll have a much smoother and more efficient computer:

1. Get rid of unwanted programs: Buy and Install NoAdware, it comes with helpful scanning tools for removing any harmful programs that have accumulated on your computer. NoAdware is one of the leading Adware & Spyware removal software on the market today.

2. Clear space on the computer: Large programs and running processes will tax your computer's runtime. If you have any Norton or Symantec programs installed, you should remove them if computer speed has become unbearable. You can go to your computer's Program Files folder and by right-clicking on folders, see which ones are taking up the most space. This info may also be available from your computer's Uninstall Programs feature (for Windows users, in the Control Panel). You should consider uninstalling large programs or programs which you rarely use. You can also use a program like RamBooster to get rid of old system files that are no longer needed.

3. Defragment the Hard Drive: On Windows computers, the DeFrag and Disk Cleanup are valuable utilities. DeFrag automatically rearranges files on your computer in an attempt to maximize computer run speed.

4. Clean the Fan: Unknown to many computer users, it's not all a matter of software. If your computer uses a fan (check the back of the computer Tower), you are actually recommended to clean it every few months (or at least I was by GeekSquad). Dust inside the tower case can accumulate, and as I personally experienced, can cause the fan to fail, which will mean the Tower overheats and your computer may refuse to start. For a good explanation of how to clean this fan (which involves opening up the Tower and using a cloth and/or compressed air can) you can see E-How's tutorial.

5. Manually Delete Temp Files: For Windows users, you can delete Temp files, Temporary Internet Files, and Cookies by going to C://Windows. You should see folders called Temp or Temporary Internet Files, and by going to the Profiles folder, can go to a user's folder and modify the Cookies saved by your computer. Temp and Temporary Internet Files folders house useless files that can accumulate and slow down your computer (particularly on shared computers). A user's Cookies folder holds site-specific files that contain login info or site preferences. However, unwanted Cookies can be harmful files downloaded by sites without your permission to attack your computer and contain Spyware or Adware. You should consider deleting Cookies for sites you do not trust.

An Introduction to LCD Technology

2009-05-09T08:17:00.001-07:00

Liquid crystals were discovered in 1888 by an Austrian botanist named Freidrich Renitzer. The phrase liquid crystal was first used by a German physicist named Otto Lehmann. Liquid crystal is a clear organic material made up of long rod shaped molecules. It was discovered that the substance had the ability to manipulate the path of light waves traveling through it. This property is used in the creation of LCD display devices.

The benefit of liquid crystal display devices over CRT based devices is that LCD devices are less bulky and take almost a third less of the volume per equivalent viewing area, than a conventional CRT. This means LCD technology is a useful component for portable devices like laptops, calculators and mobile phones. Another advantage of LCD technology is that its power usage is significantly less than that of a CRT. However, it is much more costly to manufacture an LCD TV than a CRT TV.

An LCD Televisions is a grouping of LCD elements; each of these elements produces a pixel on the screen. An LCD element consists of two major parts: a layer of liquid crystal between two lightly ridged surfaces with their ridges perpendicular to each other and two optical polarizing filters perpendicular to each other.

The long rod shaped molecules in their normal state position themselves with their axis approximately parallel to each other. As the liquid crystal flows over the finely ridged surface it is possible to manage the alignment of the molecules as they track the position of the grooves. A layer of liquid crystal substance is placed in a container with two finely ridged surfaces whose ridges are perpendicular to each other. Therefore the molecules at the two surfaces are aligned perpendicular to each other and those transitional layers are twisted by intermediate angles.

Natural light waves are positioned at random angles and flow along assorted planes from the light source. An optical polarizing filter or polarizer can separate a single plane of light from the group. The filter acts like a net of finely parallel lines blocking all light, apart from light flowing in an area specific to the lines. The light in this state is said to be polarized. A second polarizer whose lines are perpendicular to the first would block all the polarized light.

The container with ridged surfaces is positioned between two perpendicular polarizing filters. Normally light from the first filter would be blocked by the second filter. However, in this case the liquid crystal material located in-between, twists the plane of light by 90 degrees as it passes through the material. The light is now parallel to the second filter and comes out through it to the eye of the viewer. This creates a light pixel.

A battery linked across the liquid crystal container generates a current through the liquid crystal, and changes the direction of its molecules according to the path of the current flow. This disturbs the pattern of the liquid crystal molecules, so that the molecules at the ridged surfaces are no longer turned by 90 degrees. Polarized light through the first filter gets moved to a different angle by the liquid crystal when it reaches the second filter, through which it can no longer appear. An observer on the other side of the filter does not see any light coming out. This process creates a dark pixel.

Images on the LCD Televisions screen can be displayed using a large number of these cells, each operating as a light or dark pixel. Therefore, on the LCD screen each cell corresponds to one pixel. To display color each cell is made up of three sub-cells with filters over them to produce green, red or blue colored light. By controlling the volume of current in each cell, the intensity of the colored light coming from each of the cells can be manipulated. By combing the 3 primary colors of red, blue and green the entire color spectrum is conveyed to the viewer.

Explore the Many Benefits of LCD TV Technology

2009-05-09T08:16:00.000-07:00

While there have been many innovations in the world of television, the emergence of flat screen LCD TVs is certainly one of the most significant. LCD technology has created lightweight televisions that can be placed virtually anywhere or even hung on the wall. This space saving technology is one of the most significant advances in the history of television, and today's lower prices mean that an LCD TV is within reach for many more TV viewers.

Of course the prices of quality LCD televisions will still vary quite a bit from store to store and brand to brand, so it pays to shop around carefully. Off brand televisions tend to cost a good deal less than name brands like Toshiba and LG, but it is important to make sure those off brands represent good value for the money and not just a lower price. Reliability is a big factor when it comes to LCD TVs, so it is important to read the reviews and look at the reliability ratings before making a decision.

And of course the prices of LCD TVs will tend to rise along with the size of the screen. While a 15" LCD TV can often be had for just a couple hundred dollars, an LCD TV with a 42" or 52" screen can still sell for north of a thousand dollars. With so much money on the line it is definitely important to shop around and be a value conscious consumer. In addition to brand name and size one of the most important factors to consider is the number of pixels on the screen.

The higher the number of pixels the sharper the picture will be and the greater the color depth your eyes will perceive. The increased clarity and color quality is one of the reasons that 1080p LCD TVs, with their higher number of pixels, still tend to cost a great deal more than lower quality 720p sets. It is important for value conscious TV shoppers to consider their needs and choose the television that truly represents the best quality.
