Memory

Memory (also known as RAM, for Random Access Memory) is one of the most important pieces of a computer. It's what the computer actively uses while it "thinks." (As opposed to a Hard Disk, where the computer stores information for the long haul.) As of 2006, 512 MB is a fairly common amount for new computers, while a common hard drive might have 100 times that (50 GB.)
