The term "memory" is used to describe the computer's electronic circuitry that holds data and program instructions. It can be thought of as the computer's workspace and 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. Memory is sometimes referred to as primary storage, primary memory, main storage, main memory, internal storage, or random access memory (RAM). There are four major types of computer memory: random access memory, read only memory, CMOS memory, and virtual memory.

1. data for processing;
2. instructions, or programs, for processing the data;
3. data that has been processed and is waiting to be sent to...
