Techopedia Explains Primary Memory

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

As soon as a computer starts, primary memory loads 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.
