Random Access Memory (RAM) is the "working memory" in a computer. Additional RAM allows a computer to work with more information at the same time which can have a dramatic effect on total system performance.

RAM is typically referred to simply as "memory" even though other types of memory may exist inside a computer.
Each motherboard supports only a certain range of memory types in certain combinations so always check with your motherboard manufacturer before making a purchase.
A standard "module" or "stick" of desktop memory is long, thin and resembles a short ruler. The bottom of the memory module has one or more notches to guide for proper installation and is lined with numerous, usually gold-plated connectors.
Memory is installed in memory module slots located on the motherboard. These slots are easily locatable by looking for the small hinges on either side that lock the memory in place. Certain sizes of modules may need to be installed in certain slots so always check with your motherboard manufacturer before purchase or installation.
Memory modules come with various storage capabilities. Modern memory modules can be purchased in 256MB, 512MB, 1GB, 2GB, and 4GB sizes.
