What is the purpose of primary memory?

Primary memory is computer memory that a processor or computer accesses first or directly. It allows a processor to access running execution applications and services that are temporarily stored in a specific memory location. Primary memory is also known as primary storage or main memory.

Why is primary memory called so?

Its called primary because your computer processor use it as the base to store anything that’s going in process ,thus whatever is being processed in the moment ,is stored there because its fast so as to match the speed of processor.
