- hexadecimal notation — a number system having a base 16; the symbols for the numbers 0–9 are the same as those used in the decimal system, and the numbers 10–15 are usually represented by the letters A–F. The system is used as a convenient way of representing the internal binary code of a computer
- 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.
- hieroglyphic hittite — an extinct language of the Anatolian branch of Indo-European, written in a pictographic script in Syria c1200–c600 b.c.: the same language as written in cuneiform in Anatolia is known as Luwian.
- high-energy particle — Physics
- hipparchus satellite — an astronometric satellite launched in 1989 by the European Space Agency that measured the position, proper motion, and brightness of 118 218 stars down to 12th magnitude and the magnitude and colour of a million stars down to 10th magnitude

- 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.
- hydrostatic pressure — Hydrostatic pressure is the pressure exerted by a liquid that depends on how deep it is.

- hypodermic injection — the injection of a medicine or drug under the skin
- immunohistochemistry — the application of immunologic techniques to the chemical analysis of cells and tissues.
- imperfect contrition — sincere penitence or remorse.
- implicit parallelism — (parallel) A feature of a programming language for a parallel processing system which decides automatically which parts to run in parallel. The best way of providing implicit parallelism is still (1995) an active research topic. The problem is to generate the right number of parallel tasks of the right size (or "granularity"). Too many tasks and the system gets bogged down in house-keeping, or memory for waiting tasks runs out, too few tasks and processors are left idle. The best performance is usually achieved with explicit parallelism where the programmer can annotate his program to indicate which parts should be executed as independent parallel tasks.
- imported currantworm — the larva of any of several insects, as a sawfly, Nematus ribesii (imported currantworm) which infests and feeds on the leaves and fruit of currants.
- in a class by itself — unique
- in bad circumstances — (of a person) in a bad financial situation

- in flagrante delicto — Law. in the very act of committing the offense.
- in the circumstances — a condition, detail, part, or attribute, with respect to time, place, manner,agent, etc., that accompanies, determines, or modifies a fact or event; a modifying or influencing factor: Do not judge his behavior without considering every circumstance.
- in the public domain — able to be discussed and examined freely by the general public
- in-car entertainment — In-car entertainment is a sound system consisting of, for example, a radio or compact disc player, that is designed for easy operation by the driver, and to be unaffected by vibration. In larger vehicles, this system can include television and DV
- in-service education — training and education given to employed teachers throughout their career

- inferior conjunction — the alignment of an inferior planet between the sun and the earth.
- information exchange — discussion that involves exchanging ideas and knowledge
- 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.
