/werm'hohl/ n. [from the `wormhole' singularities hypothesized in some versions of General Relativity theory]
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 `device tables', `jump tables' or `capability tables'.
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.
