A method by which code and data are moved in pages from physical memory to a temporary paging file on disk

An operating-system facility that brings pages of data from disk into physical memory only as they are needed
(n ) A page transfer that enables a program's required area to be noncontiguous and partially nonresident This permits the maximum use of a system's total available memory by enabling the computer system to execute programs that are larger than the allocated physical main memory within the processor
