Describe the operation of virtual memory management
Virtual memory management uses a portion of secondary storage to expand primary storage's capacity. Programs and memory are divided into portions called pages, and each memory page is called a page frame. During program execution, one or more pages are allocated to page frames, and the rest are held in secondary storage. As pages in secondary storage are needed for current processing, the OS copies them into page frames. If necessary, pages currently in memory are written to secondary storage to make room for pages being loaded.
Each memory reference is checked to see whether the page it refers to is currently in memory. A reference to a page held in memory is called a page hit, and a reference to a page held in secondary storage is called a page fault. The OS maintains page tables to store information about page locations, allocated page frames, status of pages, and secondary storage space.
