Gigaflop A Gigaflop is a billion (the giga part) floating point operations (the flop part) per second. A floating point operation is a mathematical calculation, such as 2.277E5 * 4.3567E-7, which involves numbers in scientific form. Floating point operations are more complicated than integer operations (like 2 * 43, for example) and are a good measure of a powerful computer's processor performance.

Gopher Before the World Wide Web, "gopher" was the system for finding and displaying document files stored on the Internet.

GPS Acronym for "Global Positioning System". If you get lost in the middle of nowhere, GPS can pinpoint your exact location within mere feet. GPS is powered by a bunch of satellites (twenty-four to be exact) in geosynchronous orbit that can help you find yourself, provided you have the corresponding ground receiver. How accurate this system is depends on the sophistication of your equipment.
Graffiti Graffiti is handwriting recognition software, used to transform into text the messages you scrawl onto your PalmPilot or other personal digital assistant (PDA).
Granular The more components or options a system has, the more "granular" it is. Suppose, for example, that you have two security systems. If one lets you password-protect every page of a Web site and the other lets you password-protect every page AND certain data entry areas of each page, then the latter security system is the more granular of the two. It follows that the more granular a system is, the more flexibility it offers its users.
Gravesite A gravesite is a Web site that's still accessible but that has apparently been abandoned by its creators and/or updaters. Marketing people also use the term "gravesite" to refer to Web sites that have stopped attracting enough traffic to interest people.
