What is primary storage?
, IBM Corpration
Computer memory is prioritized according to how often that memory is required for use in carrying out operating functions. Primary storage is the means of containing primary memory (or main memory), which is the computer’s working memory and major operational component. The main or primary memory is also called “main storage” or “internal memory.” It holds relatively concise amounts of data, which the computer can access as it functions.
