[techspeak] To move information from a fast-access memory to a
|
||
slow-access memory (<span class="firstterm">swap out</span>), or
|
||
vice versa (<span class="firstterm">swap in</span>). Often refers
|
||
specifically to the use of disks as <span class="firstterm">virtual
|
||
memory</span>. As pieces of data or program are needed, they are
|
||
swapped into <a href="../C/core.html"><i class="glossterm">core</i></a> for processing; when they are no
|
||
longer needed they may be swapped out again. </p></dd><dd><p> 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 <span class="firstterm">keep
|
||
something swapped in</span> means to keep it fresh in your memory:
|
||
“<span class="quote">I reread the TECO manual every few months to keep it swapped
|
||
in.</span>” If someone interrupts you just as you got a good idea, you
|
||
might say “<span class="quote">Wait a moment while I swap this out</span>”, 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 <a href="../P/page-in.html"><i class="glossterm">page in</i></a>,
|
||
<a href="../P/page-out.html"><i class="glossterm">page out</i></a>.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="swab.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="swap-space.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">swab </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> swap space</td></tr></table></div></body></html>
