RAM define as a Random Access Memory that Primary storage of a computer is often referred to as RAM because of its random access capability. RAM chips are volatile memory.

A computer’s motherboard is designed in a manner that the memory capacity can be enhanced by adding more memory chips. The additional RAM chips, which plug into special sockets on the motherboard, are known as single-in-line memory modules (SIMMs).
