Geek: In computers and the Internet, a geekis a person who is inordinately dedicated to and involved with the technologyto the point of sometimes not appearing to be like the rest of us (non-geeks).Being a geek also implies a capability with the technology. Although historically,computer and Internet programming and hacking has been a male thing, thereare now many "girl geeks." The term "hacker" generally connotes competencemore strongly than "geek" does. The term "geek" emphasizes dedication andweirdness, although recent use of the term suggests greater social acceptanceand tolerance for geeks. (Historically, a geek was a circus person whoserole in the side-show was to bite off chicken's heads or perform otherbizarre feats. Eric Raymond describes "computer geek" as "one who eats(computer) bugs for a living.")
The term seems to be used by many in the general populace for anyonewho spends a lot of or too much time at a computer.
GEO: Geostationary Earth Orbit; a satellitethat orbits the earth directly over the equator, approximately 22,000 milesup. At this altitude, one complete trip around the earth (relative to thesun) takes 24 hours. Thus, the satellite remains over the same spot onthe earth's surface at all times, and stays fixed in the sky from any pointon the surface from which it can be "seen." So-called weather satellitesare usually of this type. You can view images from some of these satelliteson the Internet via the Purdue Weather Processor. A single geostationarysatellite can "see" approximately 40 percent of the earth's surface. Threesuch satellites, spaced at equal intervals (120 angular degrees apart),can provide coverage of the entire civilized world. A geostationary satellitecan be accessed using a dish antenna aimed at the spot in the sky wherethe satellite hovers.

Gopher: A widely successful method of makingmenus of material available over the Internet. Gopher is a Client and Serverstyle program, which requires that the user have a Gopher Client program.Although Gopher spread rapidly across the globe in only a couple of years,it has been largely supplanted by Hypertext, also known as WWW(World Wide Web). There are still thousands of Gopher Servers on the Internetand we can expect they will remain for a while.
