Page fault



memory management
In a paged virtual memory system, an access to a page (block) of memory that is not currently mapped to physical memory. When a page fault occurs the operating system either fetches the page in from secondary storage (usually disk) if the access was legitimate or otherwise reports the access as illegal.
