The working set theory of programming behavior of processes running within an operating system involves:.

The collection of pages that a process accesses.

The working set theory focuses on the idea that a process's working set is the set of pages in its address space that it is actively using or referencing during a particular period of time. It's a concept used in memory management to understand and manage the memory requirements of processes effectively. By keeping track of the working set of each process, an operating system can make better decisions about which pages to keep in physical memory to minimize page faults and optimize overall system performance.
