channel n. [IRCI The basic unit of discussion on IRC. Once one joins a channel, everything one types is read by others on that channel. Channels are named with strings that begin with a '#' sign and can have topic descriptions (which are generally irrelevant to the actual subject of discussion). Some notable channels are #initgame, #hottub, and #report. At times of international crisis, #report has hundreds of members, some of whom take turns listening to various news services and typing in summaries of the news, or in some cases, giving first-hand accounts of the action (e.g., Scud missile attacks in Tel Aviv during the Gulf War in 1991).
channel hopping n. [IRC, GEnie] To rapidly switch channels on IRC, or a GEnie chat board, just as a social butterfly might hop from one group to another at a party. This term may derive from the TV watcher's idiom, channel surfing.

chawmp n. [University of Florida] 16 or 18 bits (half of a machine word). This term was used by FORTH hackers during the late 1970s/early 1980s; it is said to have been archaic then, and may now be obsolete.
