Types of Memory in Computer
computer memory, device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. Computers represent information in binary code, written as sequences of 0s and 1s. Each binary digit (or " bit ") may be stored by any physical system that can be in either.

Memory Hierarchy. The CPU can only directly fetch instructions and data from cache memory, located directly on the processor chip. Cache memory must be loaded in from the main system memory (the Random Access Memory, or RAM). RAM however, only retains its contents when the power is on, so needs to be stored on more permanent storage.
