Those values from shared memory that a process has copied into its private memory, or those pages of virtual memory being used by a process. Changes a process makes to the values in its working set are not automatically seen by other processes.
The set of virtual addresses that are currently mapped to physical addresses. The working set is a subset of the resident set and represents a snapshot of the process' resident set.
For a process, the amount of physical memory assigned to a process by the operating system.
The set of pages that are resident for a given process while it has one or more running threads. The size of each process's working set is bounded by a minimum number of pages that the Memory Manager guarantees to be resident while the process has one running thread and by a maximum. However, the NT kernel does not necessarily constrain a process's working set to its maximum if many free pages are available. See also balance set and quota.
The section (or sections) of a mainframe program where processing is concentrated. In paging systems the size of the working set determines the (approximate) main-storage requirements for the program.
Working set is the set of physical memory pages currently dedicated to a specific process.
