19-letter words containing n, a, g, o, r
- 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).

- gigabits per second — (unit) (Gbps) A unit of information transfer rate equal to one billion bits per second. Note that, while a gigabit is defined as a power of two (2^30 bits), a gigabit per second is defined as a power of ten (10^9 bits per second, which is slightly less) than 2^30).

- grandfather's clock — a pendulum floor clock having a case as tall as or taller than a person; tall-case clock; long-case clock.
- grandmother's clock — a pendulum clock similar to a grandfather's clock but shorter.
- granuloma inguinale — a venereal disease marked by deep ulceration of the skin of the groin and external genitals, caused by the bacterium Calymmatobacterium granulomatis.
- graphic workstation — (graphics, computer) A workstation specifically configured for graphics works such as image manipulation, bitmap graphics ("paint"), and vector graphics ("draw") type applications. Such work requires a powerful CPU and a high resolution display. A graphic workstation is very similar to a CAD workstation and, given the typical specifications of personal computers currently available in 1999, the distinctions are very blurred and are more likely to depend on availability of specific software than any detailed hardware requirements.
- gratuitous contract — a contract for the benefit of only one of the parties, the other party receiving nothing as consideration.
- gravitational field — the attractive effect, considered as extending throughout space, of matter on other matter.
- great idaean mother — Cybele.
- great wall of china — a system of fortified walls with a roadway along the top, constructed as a defense for China against the nomads of the regions that are now Mongolia and Manchuria: completed in the 3rd century b.c., but later repeatedly modified and rebuilt. 2000 miles (3220 km) long.
- green mountain boys — the members of the armed bands of Vermont organized in 1770 to oppose New York's territorial claims. Under Ethan Allen they won fame in the War of American Independence
- gregorian telescope — a telescope similar in design to the Cassegrainian telescope but less widely used.

- horizontal drilling — Horizontal drilling is drilling in which the direction of the wellbore is more than 80 degrees from the vertical.
- horizontal encoding — (processor) An instruction set where each field (a bit or group of bits) in an instruction word controls some functional unit or gate directly, as opposed to vertical encoding where instruction fields are decoded (by hard-wired logic or microcode) to produce the control signals. Horizontal encoding allows all possible combinations of control signals (and therefore operations) to be expressed as instructions whereas vertical encoding uses a shorter instruction word but can only encode those combinations of operations built into the decoding logic. An instruction set may use a mixture of horizontal and vertical encoding within each instruction. Because an architecture using horizontal encoding typically requires more instruction word bits it is sometimes known as a very long instruction word (VLIW) architecture.
