- electronic commerce — (application, communications) (EC) The conducting of business communication and transactions over networks and through computers. As most restrictively defined, electronic commerce is the buying and selling of goods and services, and the transfer of funds, through digital communications. However EC also includes all inter-company and intra-company functions (such as marketing, finance, manufacturing, selling, and negotiation) that enable commerce and use electronic mail, EDI, file transfer, fax, video conferencing, workflow, or interaction with a remote computer. Electronic commerce also includes buying and selling over the web and the Internet, electronic funds transfer, smart cards, digital cash (e.g. Mondex), and all other ways of doing business over digital networks.

- ferrite core memory — (storage) (Or "core") An early form of non-volatile storage built (by hand) from tiny rings of magnetisable material threaded onto very fine wire to form large (e.g. 13"x13" or more) rectangluar arrays. Each core stored one bit of data. These were sandwiched between printed circuit boards(?). Sets of wires ran horizontally and vertically and where a vertical and horizontal wire crossed, a core had both wires threaded through it. A single core could be selected and magnetised by passing sufficient current through its horizontal and vertical wires. A core would retain its magnetisation until it was re-magnetised. The two possible polarities of magnetisation were used to represent the binary values zero and one. A third "sense" wire, passed through the core and, if the magnetisation of the core was changed, a small pulse would be induced in the sense wire which could be detected and used to deduce the core's original state. Some core memory was immersed in a bath of heated oil to improve its performance. Core memory was rendered obsolete by semiconductor memory. For example, the 1970s-era NCR 499 had two boards, each with 16 kilobytes of core memory.
- fixed-term contract — a contract for a particular and fixed period
- flannelmouth sucker — a sucker, Catostomus latipinnis, of the Colorado River and its tributaries.

- from rags to riches — a worthless piece of cloth, especially one that is torn or worn.
- gastrocolic omentum — the peritoneal fold attached to the stomach and the colon and hanging over the small intestine.
- generic programming — (programming) A programming technique which aims to make programs more adaptable by making them more general. Generic programs often embody non-traditional kinds of polymorphism; ordinary programs are obtained from them by suitably instantiating their parameters. In contrast with normal programs, the parameters of a generic programs are often quite rich in structure. For example they may be other programs, types or type constructors or even programming paradigms.
- genetic programming — (programming) (GP) A programming technique which extends the genetic algorithm to the domain of whole computer programs. In GP, populations of programs are genetically bred to solve problems. Genetic programming can solve problems of system identification, classification, control, robotics, optimisation, game playing, and pattern recognition. Starting with a primordial ooze of hundreds or thousands of randomly created programs composed of functions and terminals appropriate to the problem, the population is progressively evolved over a series of generations by applying the operations of Darwinian fitness proportionate reproduction and crossover (sexual recombination).
- geneva nomenclature — an internationally accepted system for naming organic carbon compounds.
- geomagnetic equator — an imaginary line on the earth's surface, the plane of which passes through the center and is midway between the geomagnetic poles.
- geometric isomerism — each of two or more chemical compounds having the same molecular formula but a different geometric arrangement; an unsaturated compound or ring compound in which rotation around a carbon bond is restricted, as in cis- and trans- configurations.
- glottalic airstream — a current of air in the pharynx produced by the action of the glottis.
- grandmother's clock — a pendulum clock similar to a grandfather's clock but shorter.
