Word:

prepaging

(architecture)prepaging - (Or "working set model") A technique whereby the operating system in a paging virtual memory multitasking environment loads all pages of a process's working set into memory before the process is restarted.

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