Primary Memory

Definition - What does Primary Memory mean?

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.

Techopedia explains Primary Memory

Primary memory is a computer system's volatile storage mechanism. It may be random access memory (RAM), cache memory and data buses but is primarily associated with RAM.

As soon as a computer starts, primary memory stores all running applications, including the base operating system (OS), user interface and any user installed and running software utility. A program/application that is opened in primary memory interacts with the system processor to perform all application specific tasks.

Primary memory is considered faster than secondary memory.
