From Jargon File (4.2.0, 31 JAN 2000) [jargon]:
   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}.
  
  

From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
   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.
