Main memory holds data and processing instructions temporarily until the CPU needs it.
This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions. ... Recall that a computer's memory holds data only temporarily, at the time the computer is executing a program.
There are two main kinds of semiconductor memory, volatile and non-volatile. Examples of non-volatile memory are flash memory (used as secondary memory) and ROM, PROM, EPROM and EEPROM memory (used for storing firmware such as BIOS). ... Typical secondary storage devices are hard disk drives and solid-state drives.
Primary storage, also known as main storage or memory, is the area in a computer in which data is stored for quick access by the computer's processor. The terms random access memory (RAM) and memory are often as synonyms for primary or main storage.
