  • consultant paediatrician — a paediatrician who has attained the rank of consultant
  • cooperative credit union — a cooperative group that makes loans to its members at low rates of interest.
  • cooperative multitasking — (parallel, operating system)   A form of multitasking where it is the responsibility of the currently running task to give up the processor to allow other tasks to run. This contrasts with pre-emptive multitasking where the task scheduler periodically suspends the running task and restarts another. Cooperative multitasking requires the programmer to place calls at suitable points in his code to allow his task to be descheduled which is not always easy if there is no obvious top-level main loop or some routines run for a long time. If a task does not allow itself to be descheduled all other tasks on the system will appear to "freeze" and will not respond to user action. The advantage of cooperative multitasking is that the programmer knows where the program will be descheduled and can make sure that this will not cause unwanted interaction with other processes. Under pre-emptive multitasking, the scheduler must ensure that sufficient state for each process is saved and restored that they will not interfere. Thus cooperative multitasking can have lower overheads than pre-emptive multitasking because of the greater control it offers over when a task may be descheduled. Cooperative multitasking is used in RISC OS, Microsoft Windows and Macintosh System 7.
  • crypt breakers workbench — (cbw) A freely distributable multi-window integrated workbench of tools for cryptanalysis of files encrypted with the 4.2BSD Unix crypt command. It was originally written by Robert W. Baldwin at MIT.
  • data encryption standard — (DES) The NBS's popular, standard encryption algorithm. It is a product cipher that operates on 64-bit blocks of data, using a 56-bit key. It is defined in FIPS 46-1 (1988) (which supersedes FIPS 46 (1977)). DES is identical to the ANSI standard Data Encryption Algorithm (DEA) defined in ANSI X3.92-1981. DES has been implemented in VLSI. SunOS provides a des command which can make use of DES hardware if fitted. Neither the software nor the hardware are supposed to be distributed outside the USA.

  • european monetary system — the system used in the European Union for stabilizing exchange rates between the currencies of member states and financing the balance-of-payments support mechanism. The original Exchange Rate Mechanism was formed in 1979 but superseded in 1999 when the euro was adopted as official currency of 11 EU member states. A new exchange rate mechanism (ERM II) based on the euro is used to regulate the currencies of participating states that have not adopted the euro
  • evolutionary computation — Computer-based problem solving systems that use computational models of evolutionary processes as the key elements in design and implementation. A number of evolutionary computational models have been proposed, including evolutionary algorithms, genetic algorithms, the evolution strategy, evolutionary programming, and artificial life.
  • evolutionary programming — (EP) A stochastic optimisation strategy originally conceived by Lawrence J. Fogel in 1960. An initially random population of individuals (trial solutions) is created. Mutations are then applied to each individual to create new individuals. Mutations vary in the severity of their effect on the behaviour of the individual. The new individuals are then compared in a "tournament" to select which should survive to form the new population. EP is similar to a genetic algorithm, but models only the behavioural linkage between parents and their offspring, rather than seeking to emulate specific genetic operators from nature such as the encoding of behaviour in a genome and recombination by genetic crossover. EP is also similar to an evolution strategy (ES) although the two approaches developed independently. In EP, selection is by comparison with a randomly chosen set of other individuals whereas ES typically uses deterministic selection in which the worst individuals are purged from the population.
  • exponential distribution — a continuous single-parameter distribution used esp when making statements about the length of life of certain materials or waiting times between randomly occurring events. Its density function is p(x) = λe–λx for positive λ and nonnegative x, and it is a special case of the gamma distribution
  • extra-sensory perception — Extra-sensory perception means knowing without using your ordinary senses such as sight and hearing. Some people believe this is possible. The abbreviation ESP is also used.
  • fish protein concentrate — an odorless and tasteless high-protein food additive made from ground fish and suitable for human consumption. Abbreviation: FPC.
  • floating point underflow — underflow
  • floating-point specratio — SPECfp92

  • frequent shopper program — A frequent shopper program is one that rewards customers for purchases made on multiple visits, and builds up points entitling them to reduced prices and free items.
  • frequent-flyer programme — a plan or system under which frequent flyers earn rewards for being regular customers
  • general protection fault — General Protection Failure
  • geographical determinism — the theory that human activity is determined by geographical conditions

  • graduated pension scheme — (between 1961 and 1975) an earnings-related pension scheme which was based on the amount of an employee's National Insurance contributions
  • graphical user interface — a software interface designed to standardize and simplify the use of computer programs, as by using a mouse to manipulate text and images on a display screen featuring icons, windows, and menus.
  • great saint bernard pass — St. Bernard, Great.
  • ground-fault interrupter — a circuit breaker that senses currents caused by ground faults and quickly shuts off power before damage can occur to generating equipment.
  • gulf cooperation council — an association of Persian Gulf nations formed for the purpose of collective defense against aggression. Abbreviation: GCC.
  • hairdressing appointment — an appointment to have your hair cut, styled, coloured, etc, at a hairdresser
  • have a finger in the pie — any of the terminal members of the hand, especially one other than the thumb.

  • have had a drop too much — to be drunk
  • have the drop on someone — to have the advantage over someone
  • heart in the right place — If you say that someone's heart is in the right place, you mean that they are kind, considerate, and generous, although you may disapprove of other aspects of their character.
  • hexaethyl tetraphosphate — a yellow, very poisonous liquid, (C 2 H 5 O) 6 P 4 O 7 , soluble in water, used as an insecticide.
  • high bypass ratio engine — a type of by-pass engine in which a large fan driven by a turbine and housed in a short duct forces air rearwards around the exhaust gases in order to increase the propulsive thrust
  • high performance fortran — (language)   (HPF) A data parallel language extension to Fortran 90 which provides a portable programming interface for a wide variety of target platforms. The original HPF language specification was produced by the High Performance Fortran Forum, a broad consortium of industry and academia, which met regularly throughout 1992 and early 1993. HPF compilers are now available on most commonly-used computing systems, and users are beginning to gain first hand experience with this language. The Forum has continued to meet in order to address advanced topics.
  • high performance routing — (networking)   (HPR) Routing designed to work in conjunction with APPN Intermediate Session Routing (ISR) network nodes. HPR nodes perform many of the same functions as ISR nodes. For example, HPR nodes use the same method of calculating routes based on the Topology Routing Service database and class of service tables. HPR nodes also supports such APPN features as connection networks and support for parallel transmission groups (TGs). In the HPR architecture, both partner nodes must support HPR for RTP connections to take place between the nodes. If one node supports HPR and the partner node does not, then the link will support ISR functionality only.
  • homolographic projection — an equal-area projection in which the proportion between regions of unequal area is correctly shown.
  • hoop-petticoat narcissus — petticoat narcissus.
