  • interdepartmental — involving or existing between two or more departments: interdepartmental rivalry.
  • interdependencies — the quality or condition of being interdependent, or mutually reliant on each other: Globalization of economies leads to an ever-increasing interdependence of countries.
  • interdisciplinary — combining or involving two or more academic disciplines or fields of study: The economics and history departments are offering an interdisciplinary seminar on Asia.
  • internet explorer — (web)   (IE, MSIE) Microsoft's free World-Wide Web browser for Microsoft Windows, Windows 95, Windows NT, and Macintosh. Internet Explorer is the main rival to Netscape Navigator (which runs on many more platforms). Both support the same core features and offer incompatible extensions. Microsoft combined later versions of IE with their file system browser, "Explorer" and bundled it with Windows 95 in an attempt to use their dominance of the desktop operating system market to force users to abandon Netscape's browser, which they perceived as a potential threat. This, and other dubious business moves, became the subject of a US Department of Justice antitrust trial in late 1998/early 1999.
  • internet protocol — (networking)   (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. It provides packet routing, fragmentation and re-assembly through the data link layer. IPv4 is the version in widespread use and IPv6 was just beginning to come into use in 2000 but is still not widespread by 2008.
  • internet provider — Internet Service Provider
  • interprofessional — following an occupation as a means of livelihood or for gain: a professional builder.
  • interrelationship — reciprocal relation.
  • interrupt handler — (software)   A routine which is executed when an interrupt occurs. Interrupt handlers typically deal with low-level events in the hardware of a computer system such as a character arriving at a serial port or a tick of a real-time clock. Special care is required when writing an interrupt handler to ensure that either the interrupt which triggered the handler's execution is masked out (inhibitted) until the handler exits, or the handler is re-entrant so that multiple concurrent invocations will not interfere with each other. If interrupts are masked then the handler must execute as quickly as possible so that important events are not missed. This is often arranged by splitting the processing associated with the event into "upper" and "lower" halves. The lower part is the interrupt handler which masks out further interrupts as required, checks that the appropriate event has occurred (this may be necessary if several events share the same interrupt), services the interrupt, e.g. by reading a character from a UART and writing it to a queue, and re-enabling interrupts. The upper half executes as part of a user process. It waits until the interrupt handler has run. Normally the operating system is responsible for reactivating a process which is waiting for some low-level event. It detects this by a shared flag or by inspecting a shared queue or by some other synchronisation mechanism. It is important that the upper and lower halves do not interfere if an interrupt occurs during the execution of upper half code. This is usually ensured by disabling interrupts during critical sections of code such as removing a character from a queue.
  • interrupt request — (IRQ) The name of an input found on many processors which causes the processor to suspend normal instruction execution temporarily and to start executing an interrupt handler routine. Such an input may be either "level sensitive" - the interrupt condition will persist as long as the input is active or "edge triggered" - an interrupt is signalled by a low-to-high or high-to-low transition on the input. Some processors have several interrupt request inputs allowing different priority interrupts.
  • interrupted screw — a screw having the thread interrupted in one or more places by longitudinal channels, as in the breech of a cannon or the lead screw of a lathe.
  • intestinal bypass — the surgical circumvention, by anastomosis, of a diseased portion of the intestine; also sometimes used to reduce nutrient absorption in morbidly obese patients.
  • intradepartmental — Within a department.
  • intraspecifically — Between individuals of the same species.
  • introspectiveness — characterized by introspection, the act or process of looking into oneself.
  • inversion therapy — a method used to stretch and align the body, especially the lower back, by suspending the entire body upside down from an apparatus that grips or supports the feet or knees.
  • invisible exports — services sold to a foreign country or countries
  • invisible imports — imports of services rather than goods
  • iontophoretically — By means of iontophoresis.
  • irreproducibility — The quality of not being reproducible.
  • isoelectric point — the pH at which a substance is electrically neutral or at which it is at its minimum ionization.
  • j. presper eckert — (person)   One of the developers of ENIAC.
  • japanese chestnut — any of the several deciduous trees constituting the genus Castanea, of the beech family, having toothed, oblong leaves and bearing edible nuts enclosed in a prickly bur, and including C. dentata (American chestnut) which has been virtually destroyed by the chestnut blight, C. sativa (European chestnut) C. mollissima (Chinese chestnut) and C. crenata (Japanese chestnut)
  • japanese clematis — a Japanese woody vine, Clematis paniculata, of the buttercup family, having dense clusters of fragrant, white flowers and plumed fruit.
  • japanese knotweed — Mexican bamboo.
  • japanese wisteria — a wisteria, Wisteria floribunda, of Japan, having violet, violet-blue, pink, red, or white flowers, grown in the U.S. as an ornamental.
  • job specification — a detailed description of the qualifications, skills, and experience required for a particular post of employment
  • john peter zenger — John Peter, 1697–1746, American journalist, printer, and publisher, born in Germany: his libel trial and eventual acquittal (1735) set a precedent for establishing freedom of the press in America.
  • joined at the hip — friends: inseparable
  • judgment of paris — the decision by Paris to award Aphrodite the golden apple of discord competed for by Aphrodite, Athena, and Hera.
  • jump trace buffer — (JTB) A feature of some pipelined processors (e.g. Amulet, Pentium?) which stores the source and destination addresses of the last few branch instuctions executed. When a branch instruction is fetched, its source is looked for in the JTB. If found, the next instuction fetch will be from the previous destination of that branch. If it turns out that the branch shouldn't have been taken this time, then the pipeline is flushed. This means that in a tight loop it is not necessary to flush the pipeline every time you jump back to the start.
  • jurisprudentially — In terms of jurisprudence.
  • jus primae noctis — droit du seigneur.
  • karitane hospital — a hospital for young babies and their mothers
  • keep mum/stay mum — If you keep mum or stay mum about something, you do not tell anyone about it.

  • kitchen appliance — a machine intended for use in the kitchen, such as a fridge or a food processor
  • know when to stop — If you say that someone does not know when to stop, you mean that they do not control their own behaviour very well and so they often annoy or upset other people.
  • l'hospital's rule — the theorem that for the quotient of two functions satisfying certain conditions on a given closed interval, each having infinite limit or zero as limit at a given point, the limit of the quotient at the given point is equal to the limit of the quotient of the derivatives of each function.

  • least fixed point — (mathematics)   A function f may have many fixed points (x such that f x = x). For example, any value is a fixed point of the identity function, (\ x . x). If f is recursive, we can represent it as f = fix F where F is some higher-order function and fix F = F (fix F). The standard denotational semantics of f is then given by the least fixed point of F. This is the least upper bound of the infinite sequence (the ascending Kleene chain) obtained by repeatedly applying F to the totally undefined value, bottom. I.e. fix F = LUB {bottom, F bottom, F (F bottom), ...}. The least fixed point is guaranteed to exist for a continuous function over a cpo.
  • least upper bound — an upper bound that is less than or equal to all the upper bounds of a particular set. 3 is the least upper bound of the set consisting of 1, 2, 3. Abbr.: lub.
