Memory

Memory is defined as the computer's workspace (physically, a collection of RAM chips). It is an important resource, since it determines the size and number of programs that can be run at the same time, as well as the amount of data that can be processed instantly. All program execution and data processing takes place in memory. The program's instructions are copied into memory from disk or tape and then extracted from memory into the control unit circuit for analysis and execution. The instructions direct the computer to input data into memory from a keyboard, disk, tape or communications channel.
