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.

hard gelatin capsule — A hard gelatin capsule is a type of capsule that is usually used to contain medicine in the form of dry powder or very small pellets.
hardware handshaking — (communications) A technique for regulating the flow of data across an interface by means of signals carried on separate wires. A common example is the RTS (Request to Send) and CTS (Clear to Send) signals on an EIA-232 serial line. The alternative, software handshaking, uses two special characters inserted into the data stream to carry the same information.

helmeted guinea fowl — the common guinea fowl in its wild state.
herringbone bridging — Carpentry. cross bridging.
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.
high-density housing — housing with a higher population density than the average, typically blocks of flats, and tower blocks
high-energy particle — Physics
hildegard von bingen — Hildegard von (Hildegard of Bingen"Sibyl of the Rhine") 1098–1178, German nun, healer, writer, and composer.

integration by parts — Mathematics. a method of evaluating an integral by use of the formula, ∫udv = uv − ∫vdu.
integrity constraint — (database) A constraint (rule) that must remain true for a database to preserve data integrity. Integrity constraints are specified at database creation time and enforced by the database management system. Examples from a genealogical database would be that every individual must be their parent's child or that they can have no more than two natural parents.
intelligence officer — a military officer responsible for collecting and processing data on hostile forces, weather, and terrain.
intelligence service — the government department that is responsible for collecting and analyzing information about enemies
intelligent database — (database) A database management system which performs data validation and processing traditionally done by application programs. Most DBMSs provide some data validation, e.g. rejecting invalid dates or alphabetic data entered into money fields, but often most processing is done by application programs. There is however no limit to the amount of processing that can be done by an intelligent database as long as the process is a standard function for that data. Examples of techniques used to implement intelligent databases are constraints, triggers and stored procedures. Moving processing to the database aids data integrity because it is guaranteed to be consistent across all uses of the data. Mainframe databases have increasingly become more intelligent and personal computer database systems are rapidly following.
intelligent terminal — (hardware) (or "smart terminal", "programmable terminal") A terminal that often contains not only a keyboard and screen, but also comes with a disk drive and printer, so it can perform limited processing tasks when not communicating directly with the central computer. Some can be programmed by the user to perform many basic tasks, including both arithmetic and logic operations. In some cases, when the user enters data, the data will be checked for errors and some type of report will be produced. In addition, the valid data that is entered may be stored on the disk, it will be transmitted over communication lines to the central computer. An intelligent terminal may have enough computing capability to draw graphics or to offload some kind of front-end processing from the computer it talks to. The development of workstations and personal computers has made this term and the product it describes semi-obsolescent, but one may still hear variants of the phrase "act like a smart terminal" used to describe the behaviour of workstations or PCs with respect to programs that execute almost entirely out of a remote server's storage, using said devices as displays. The term once meant any terminal with an addressable cursor; the opposite of a glass tty. Today, a terminal with merely an addressable cursor, but with none of the more-powerful features mentioned above, is called a dumb terminal. There is a classic quote from Rob Pike (inventor of the blit terminal): "A smart terminal is not a smart*ass* terminal, but rather a terminal you can educate". This illustrates a common design problem: The attempt to make peripherals (or anything else) intelligent sometimes results in finicky, rigid "special features" that become just so much dead weight if you try to use the device in any way the designer didn't anticipate. Flexibility and programmability, on the other hand, are *really* smart. Compare hook.
international gothic — a style of Gothic art, especially painting, developed in Europe in the late 14th and early 15th centuries, chiefly characterized by details carefully delineated in a naturalistic manner, elongated and delicately modeled forms, the use of complex perspective, and an emphasis on the decorative or ornamental aspect of drapery, foliage, or setting.
international orange — a shade of bright orange, highly visible at a great distance and in murky weather, used to color aircraft, airport towers and hangars, boats, etc., for safety or rescue purposes.
