    The word ""Main"" is used to distinguish it from external mass storage devices such as disk drives.The main memory of the computer is also known as RAM, standing for Random Access Memory.Main memory is expensive as compared to external memory so it has limited capacity. In Main Memory when programs and data become active, they are copied from secondary memory into main memory where the processor can interact with them.
