(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].
