architecture The set of all pages (in a paging virtualmemory system) used by a process during some time interval.
As a result of locality of reference, the working set
frequently consists of a relatively small fraction of a
process's total virtual memory pages. While a process's
entire working set is in physical memory the process will
run without page faults. If the working set is too large
for available physical memory, the process causes frequent
In a multitasking environment, information about which pages
are in each process's working set allows the memory management
system to improve CPU efficiency by prepaging (also called
