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.

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.

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.

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.

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.

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.

Most likely, the blue screen is the worst error in all the PC's. To tell the truth, the edition of the Windows that one is using has no influence on whether it can suffer from blue screen error or not, because all windows can experience this error. And so, this guide is not only intended for the Windows XP Blue Screen but for all the editions of the Windows.

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.
