Computer memory is a generic term for all of the different types of data storage technology that a computer may use, including RAM, ROM, and flash memory.. You … The system memory is the place where the computer holds current programs and data that are in use. There are various levels of computer memory, including ROM, RAM, cache, page and graphics, each with specific objectives for system operation. Memory is internal storage areas in the computer system. Systems CTSS One of the first time-sharing operating systems Developed at MIT by a group known as Project MAC Ran on a computer with 32,000 36-bit words of main memory, with the resident monitor consuming 5000 of that To simplify both the monitor and memory management a program was always loaded to start at the Computer memory is a location in which various data is stored in a computer system. RAM can have many of the types.
