Memory considerations 1. Virtual memory is one of the more important advances in computer systems to come out of the 1960s. The idea is simple, although the implementation is complicated. The user is supplied with very large virtual memory. This memory is subdivided into blocks of modest size called pages. Since the entire virtual memory cannot be contained in fast, main memory, most of its pages are maintained on a slower backing store, usually a disk. Only a few active pages are contained in the main memory.
