  • 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.
  • 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.
  • 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.
  • half wave rectifier — A half wave rectifier removes the negative component of an alternating signal leaving only the positive part.
  • half-wave rectifier — a rectifier that changes only one half of a cycle of alternating current into a pulsating, direct current.
  • 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
  • hatfield-mccoy feud — a blood feud between two mountain clans on the West Virginia–Kentucky border, the Hatfields of West Virginia and the McCoys of Kentucky, that grew out of their being on opposite sides during the Civil War and was especially violent during 1880–90.

  • 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.
