prepaging

(architecture)(Or "working set model") A technique wherebythe operating system in a paging virtual memorymultitasking environment loads all pages of a process'sworking set into memory before the process is restarted.

Under demand paging a process accesses its working set bypage faults every time it is restarted. Under prepaging thesystem remembers the pages in each process's working set andloads them into physical memory before restarting the process.Prepaging reduces the page fault rate of reloaded processesand hence generally improves CPU efficiency.
