Summary

Primary storage, also known as main memory, is a crucial component in computer systems. It is required to store and access data and instructions that the computer's processor uses during its operations. Think of primary storage as a temporary workspace for the CPU. Without it, the computer would be unable to run applications or perform tasks efficiently.

Primary storage consists of Random Access Memory (RAM) and cache memory. RAM holds data that the computer is currently using, while cache memory stores frequently accessed data for faster retrieval. These memories are volatile, meaning their contents are lost when the computer is turned off.

Primary storage is essential for computer systems as it enables speedy access to data and ensures smooth functioning of applications and programs.
