singularities hypothesized in some versions of General Relativity theory]
</p></dd><dd><p> 1. [n.,obs.] A location in a monitor which contains the address of a
routine, with the specific intent of making it easy to substitute a
different routine. This term is now obsolescent; modern operating systems
use clusters of wormholes extensively (for modularization of I/O handling
in particular, as in the Unix device-driver organization) but the preferred
techspeak for these clusters is &#8216;device tables&#8217;, &#8216;jump
tables&#8217; or &#8216;capability tables&#8217;. </p></dd><dd><p> 2. [Amateur Packet Radio] A network path using a commercial
satellite link to join two or more amateur VHF networks. So called because
traffic routed through a wormhole leaves and re-enters the amateur network
over great distances with usually little clue in the message routing header
as to how it got from one relay to the other. Compare
