swap
     
         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.
