Upgrading your computer memory is one of the quickest, easiest, and least expensive ways to increase performance. Also called RAM, or Random Access Memory, these memory cards are often confused with disk space. Disk space refers to the amount of storage on your hard drive where your data is kept. RAM is the area where all the computing goes on.You can draw an analogy from the world of pen and paper. Disk space on the hard drive can be compared to a filing cabinet. All your documents, photos, and ledgers are stored on your hard drive in folders, just like files in a filing cabinet. On your office desk you will write documents, create photo albums, and tally spreadsheets. Using the memory computer is like your office desk. The memory is where your computer places the files that you are going to work on.

When you open a document on your computer, you remove it from your virtual filing cabinet, the hard drive, and place it on your electronic desk, the memory. Your programs make your modifications to the document while it is in memory and then writes these changes back to the hard drive when the document is saved. This, by the way, is why you might lose all your current work if your computer shuts down unexpectedly. Your program has not written the changes back to the hard drive yet, thus you lose all the work that you have done.How much memory should you have? Well, the short answer is the more the better. The amount of memory your computer can use is governed by several factors. First, the amount of memory you can install will depend on the main board of the computer. Check your computers documentation for its limitations. Secondly, the operating system you are using will have a maximum amount of memory computer can use. For example, Windows XP, the system that is found on many home computers, can use up to 4 Gigabytes of memory. It can use less, but the operating system itself needs at least 512 megabytes of RAM just to run. Begin running several programs and you will need more. And the more programs you run at the same time, the more memory the computer should have. If your machine does not have enough memory, it will borrow space from the hard drive, which will be much slower.

Think back to your desk for a minute. You might have a work lamp, a pen and pencil holder, a calculator, and several other items to help you work. You might have to shuffle papers around a lot if you have a small desk and that will slow you down. Your computer operates the same way. If you have several programs running in the background, like anti-virus software and a scheduler, and then you start running a word processor, spreadsheet, and the internet browser, your virtual desk starts to run out of room. Adding more memory will give your computer a bigger desk.
