	swap
 vt.

    1. [techspeak] To move information from a fast-access memory to a
    slow-access memory (swap out), or vice versa (swap in). Often refers
    specifically to the use of disks as virtual memory. As pieces of data or
    program are needed, they are swapped into core for processing; when they
    are no longer needed they may be swapped out again.

    2. The jargon use of these terms analogizes people's short-term memories
    with core. Cramming for an exam might be spoken of as swapping in. If you
    temporarily forget someone's name, but then remember it, your excuse is
    that it was swapped out. To keep something swapped in means to keep it
    fresh in your memory: ?I reread the TECO manual every few months to keep it
    swapped in.? If someone interrupts you just as you got a good idea, you
    might say ?Wait a moment while I swap this out?, implying that a piece of
    paper is your extra-somatic memory and that if you don't swap the idea out
    by writing it down it will get overwritten and lost as you talk. Compare
    page in, page out.

swapping

    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.
