RAM defined 

RAM is an abbreviation for Random Access Memory, the working memory in your PC. As your computer runs programs and works with data, it uses RAM to store the program information. RAM is usually measured in megabytes (MB). More RAM allows your computer to run more complex programs and to do so faster. RAM also allows you to "multitask," or work among several open programs. For example, working on a Word document as you surf the Internet and listen to MP3 music files can be very draining on your computer's RAM. After the processor, RAM is the second biggest factor in overall system speed. If you work with large spreadsheets or digital images, having more RAM is a big help.

Choosing RAM: Aim high

Choosing RAM is similar to choosing a processor; keep in mind your future needs. Also similar to processors, graphics and digital imaging, as well as gaming and multimedia software, tend to require the most RAM to run smoothly and effectively. You may be able to run the hottest new games with out-of-date RAM, but game play might play slow, or some game features may be disabled in order to free up memory. Likewise, graphics files are comparatively much larger than text files, and can slow your system down if you have insufficient RAM. Another factor to keep in mind is whether you'll be multitasking—a memory robbing practice that can often go unnoticed by the user, especially when programs such as virus protection don't make their presence known. The Internet is another drain to RAM, especially when you open multiple browser windows, some of which may be featuring sites packed with animation and graphics.
