swap space

Computing Dictionary

swap space definition

operating system
An area of disk (e.g. a swap file) used to store the state of a process that has been swapped out. Under a virtual memory system, it is the amount of swap space rather than the amount of physical memory which determines the maximum size of a single process and the maximum total size of all active processes.
