Generic term used to refer to any memory device that provides backup storage besides the main memory. Secondary memory is lower-level, larger capacity, and usually a set of disks. Only data and programs currently used by the processor reside in main memory. All other information (not needed at a specific time) is stored in secondary memory and is transferred to main memory on a demand basis.
