greenwich hour angle — hour angle measured from the meridian of Greenwich, England.
group code recording — (storage) (GCR) A recording method used for 6250 BPI magnetic tapes. GCR typically uses a group of five bits of code to represent four bits of data. The encoding ensures no more than two or three zeros occur in a row, and no more than eight or so ones occur in a row, where zeros represent an absense of magnetic change. GCR is also used on Commodore Business Machines diskette drives; the 4040, 8050, 154x, 157x and 158x series of 5.25" and 3.5" low and high density diskette drives used with 8-bit home computers circa 1977 to 1992. It was also supported on Amiga internal and external drives but only used for reading non-Amiga disks. Compare NRZI, PE.

hierarchical routing — The complex problem of routing on large networks can be simplified by breaking a network into a hierarchy of smaller networks, where each level is responsible for its own routing. The Internet has, basically, three levels: the backbones, the mid-levels, and the stub networks. The backbones know how to route between the mid-levels, the mid-levels know how to route between the sites, and each site (being an autonomous system) knows how to route internally. See also Exterior Gateway Protocol, Interior Gateway Protocol, transit network.

horizontal microcode — (processor) Microcode using horizontal encoding.
horizontal scan rate — (hardware) (HSR) The measure of how many scan lines of pixels a monitor can display in one second, expressed in kHz (generally somewhere between 20 and 100 kHz). The HSR is controlled by the horizontal sync signal generated by the video controller, but is limited by the speed with which the monitor can scan the electron beam horizontally across the screen and then return it to the beginning of the next line.

instruction mnemonic — (programming) A word or acronym used in assembly language to represent a binary machine instruction operation code. Different processors have different instruction sets and therefore use a different set of mnemonics to represent them. E.g. ADD, B (branch), BLT (branch if less than), SVC, MOVE, LDR (load register).
instruction prefetch — (architecture) A technique which attempts to minimise the time a processor spends waiting for instructions to be fetched from memory. Instructions following the one currently being executed are loaded into a prefetch queue when the processor's external bus is otherwise idle. If the processor executes a branch instruction or receives an interrupt then the queue must be flushed and reloaded from the new address. Instruction prefetch is often combined with pipelining in an attempt to keep the pipeline busy. By 1995 most processors used prefetching, e.g. Motorola 680x0, Intel 80x86.
