swap space

   <operating system> An area of disk (e.g. a {swap file}) used
   to store the state of a process that has been {swap}ped 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.
