Computer memory is an essential component of any computer system. It is divided into several categories, including Random Access Memory (RAM), CORE Memory (CORE), Megabyte (MEG), Byte (BYTE), Read-Only Memory (ROM), and STORAGE (STORAGE). RAM is a type of volatile memory that stores data temporarily while the computer is running. CORE is a type of non-volatile memory that stores data permanently. MEG is a unit of measurement for computer memory, equal to one million bytes. BYTE is a unit of measurement for computer memory, equal to eight bits. ROM is a type of non-volatile memory that stores data permanently and cannot be changed. STORAGE is a type of non-volatile memory that stores data permanently and can be accessed by the computer.
