swapping

   <operating system> To move a program from fast-access memory
   to a slow-access memory ("swap out"), or vice versa ("swap
   in").  The term often refers specifically to the use of a
   {hard disk} (or a {swap file}) as {virtual memory} or "swap
   space".

   When a program is to be executed, possibly as determined by a
   {scheduler}, it is swapped into {core} for processing; when it
   can no longer continue executing for some reason, or the
   scheduler decides its {time slice} has expired, it is swapped
   out again.

   This contrasts with "paging" systems in which only parts of a
   program's memory is transfered.
