RAM (random access memory)

System Memory or RAM
Random Access Memory (RAM) provides the fast, temporary storage from which your CPU draws the data it needs to operate. The storage capacity of RAM is measured in megabytes (millions of bytes). You'll want to build your new PC with an absolute minimum of 64 MB of RAM. If you are running very demanding applications or high data throughput jobs like video editing, you might want to install as much memory as you can afford. Currently, 256 MB is a pretty healthy amount, and is more than is included in most PCs sold in stores.

There are three basic families of RAM in use today, and we give an example of each with our three builds. The Dynamic RAM (DRAM) that makes up the system memory actually starts to forget everything many times a second, but a dedicated memory controller endlessly reads and writes this information to keep it fresh. Memory, amusingly enough, does forget everything the moment the PC is turned off, which is why we have hard drives, CDS, and floppies to provide storage. The fastest way to tip off a showroom vulture that you are a little hazy about computer terminology is to refer to "the memory in the hard drive."
