  • gastroenterological — Of or pertaining to gastroenterology.
  • general anaesthetic — sth administered to induce unconsciousness

  • general post office — (in the U.S. postal system) the main post office of a city, county, etc., that also has branch post offices. Abbreviation: G.P.O., GPO.
  • generic array logic — (hardware, integrated circuit)   (GAL) A newer kind of Programmable Array Logic based on EEPROM storage cells, been pioneered by Lattice. GALs can be erased and reprogrammed and usually replace a whole set of different PALs (hence the name).
  • 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).
  • geocentric parallax — the apparent displacement of an observed object due to a change in the position of the observer.
  • 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.
  • gestational carrier — surrogate mother (def 3).
  • 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).
  • giraldus cambrensis — literary name of Gerald de Barri. ?1146–?1223, Welsh chronicler and churchman, noted for his accounts of his travels in Ireland and Wales
  • glottochronological — Of or pertaining to glottochronology.

  • grandfather's chair — wing chair.
  • 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.
  • 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.
  • great-grandchildren — a grandchild of one's son or daughter.
  • greenstick fracture — an incomplete fracture of a long bone, in which one side is broken and the other side is still intact.
  • greenwich mean time — the time as measured on the prime meridian running through Greenwich, England: used in England and as a standard of calculation elsewhere.
  • gregorian telescope — a telescope similar in design to the Cassegrainian telescope but less widely used.
  • grievance committee — a group of representatives chosen from a labor union or from both labor and management to consider and remedy workers' grievances.
  • grievance procedure — the established series of steps to be taken in dealing with a grievance raised with an employer by an employee
  • guerrilla financing — the use of unconventional and marginally legal means to capitalize enterprises
  • gulf of carpentaria — a shallow inlet of the Arafura Sea, in N Australia between Arnhem Land and Cape York Peninsula
  • halt and catch fire — (humour, processor)   (HCF) Any of several undocumented and semi-mythical machine instructions with destructive side-effects, supposedly included for test purposes on several well-known architectures going as far back as the IBM 360. The Motorola 6800 microprocessor was the first for which an HCF opcode became widely known. This instruction caused the processor to read every memory location sequentially until reset.
  • hang in the balance — to fasten or attach (a thing) so that it is supported only from above or at a point near its own top; suspend.
  • harmonic distortion — distortion caused by nonlinear characteristics of electronic apparatus, esp of audio amplifiers, that generate unwanted harmonics of the input frequencies
  • have a bone to pick — to have grounds for a quarrel
  • heel-and-toe racing — race walking.

  • 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.
  • hotel accommodation — the facilities and the quality of accommodation provided by a hotel
