It is common for modern processors to be running multiple processes at one time. Each process has an address space associated with it. To create a whole complete address space for each process would be much too expensive, considering that processes may...

A swap file is a file used by an operating system, or a specific program, as part of the virtual memory exchange of information between the random-access memory (RAM) chip drives and the read-only memory (ROM) disk drives. Swap files occupy swap space...

Virtual memory is a model—one of many possible models—for managing the resource of physical memory, or main memory. Such management is necessary because a microprocessor, the heart of a computer, has direct access only to main memory,...
