- Better known as RAM. One or more memory chips that can be read and written by the CPU and other hardware, and which serve as the primary workspace of a computer. Instructions and data are loaded here for subsequent execution or processing, and its storage locations may be accessed in any desired order. The amount of main memory a computer has determines factors such as how many programs may be optimally run simultaneously. Also called main storage, random access memory, read/write memory, read/write RAM, primary memory, primary storage, or core memory (2).
