ChiteCture> (Or "working set model") A teChnique whereby the operating system in a pagingvirtual memorymultitasking 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. ["Modern Operating Systems", Andrew S. Tanenbaum, pub. PrentiCe Hall, InC. 1992].
