  • execute channel program — (operating system)   (EXCP) An IBM system for low-level file access, where the programmer is completely responsible for providing a list of device-specific "channel comands" to be executed by I/O channels, control units and/or devices. The operating system will simply check the "CCW" chains for security purposes (access invalid memory or outside of file extents) and then schedule them for execution.
  • experimental psychology — the scientific study of the individual behaviour of man and other animals, esp of perception, learning, memory, motor skills, and thinking
  • extended reach drilling — Extended reach drilling is drilling a well horizontally to at least twice its vertical depth.
  • extravehicular activity — the act or an instance of floating and manoeuvring in space, outside but attached by a lifeline to a spacecraft
  • fall between the cracks — to fail to fit into a given agenda or program
  • fall through the cracks — to break without complete separation of parts; become fissured: The plate cracked when I dropped it, but it was still usable.
  • fendalton shopping cart — a four-wheel drive recreational vehicle
  • fluorochlorohydrocarbon — (organic chemistry) Any compound formally derived from a hydrocarbon by replacing some hydrogen atoms with fluorine and some with chlorine (at least one being retained).
  • four colour map theorem — (mathematics, application)   (Or "four colour theorem") The theorem stating that if the plane is divided into connected regions which are to be coloured so that no two adjacent regions have the same colour (as when colouring countries on a map of the world), it is never necessary to use more than four colours. The proof, due to Appel and Haken, attained notoriety by using a computer to check tens of thousands of cases and is thus not humanly checkable, even in principle. Some thought that this brought the philosophical status of the proof into doubt. There are now rumours of a simpler proof, not requiring the use of a computer. See also chromatic number
  • fraunhofer gesellschaft — (company)   (FhG, FhG IIS, Institut für Integrierte Schaltungen) A german company, named after the physicist. IIS is Integrated Circuit Institute. FhG are known for their research on audio compression, especially MPEG-1 Layer-3 (MP3).
  • fully associative cache — (memory management)   A type of cache in which data from any address can be stored in any cache location. The whole address must be used as the tag (the value that identifies a block of data in the cache). All tags must be compared simultaneously (associatively) with the requested address and if one matches then its associated data is accessed. This requires an associative memory to hold the tags which makes this form of cache more expensive. It does however solve the problem of contention for cache locations (cache conflict) since a block need only be flushed when the whole cache is full and then the block to flush can be selected in a more efficient way. The alternatives are direct mapped cache or set associative cache.
  • function graph language — (language)   (FGL) The machine language for the AMPS (Applicative Multi-Processing System) proposed by Robert Keller, Gary Lindstrom and Suhas Patil at the University of Utah.
  • grand duchess charlotte — Grand Duchess (Charlotte Aldegonde Elise Marie Wilhelmine) 1896–1985, sovereign of Luxembourg 1919–64.
  • grant-maintained school — a school funded directly by central government
  • graphical kernel system — (graphics, standard)   (GKS) The widely recognised standard ANSI X3.124 for graphical input/output. GKS is worked on by the ISO/IEC group JTC1/SC24. It provides applications programmers with standard methods of creating, manipulating, and displaying or printing computer graphics on different types of computer graphics output devices. It provides an abstraction to save programmers from dealing with the detailed capabilities and interfaces of specific hardware. GKS defines a basic two-dimensional graphics system with: uniform input and output primitives; a uniform interface to and from a GKS metafile for storing and transferring graphics information. It supports a wide range of graphics output devices including such as printers, plotters, vector graphics devices, storage tubes, refresh displays, raster displays, and microfilm recorders.
  • have tickets on oneself — to be conceited
  • health maintenance plan — A health maintenance plan is a health insurance policy that provides preventive care like vaccinations, doctor checkups, and screenings, for a prepaid fee.

  • hierarchical navigation — (web)   On a web page, any type of menu whose hierarchical structure matches that of the site to which the page belongs. A hierarchical navigation menu allows the user to jump ("navigate") directly to a section of the site several levels below the top. The menu may present only a fixed number of levels rather than the whole structure.
  • hold sb/sth in contempt — If you hold someone or something in contempt, you feel contempt for them.
  • hollerithabetical order — (algorithm)   Sorted into the order a standard Hollerith card sorting machine produces, with special characters interleaved within the alphabet.

  • human leukocyte antigen — HLA.
  • hydrochlorofluorocarbon — Any of a class of inert compounds of carbon, hydrogen, hydrocarbons, chlorine, and fluorine, used in place of chlorofluorocarbons as being somewhat less destructive to the ozone layer.
  • hypothetical imperative — (esp in the moral philosophy of Kant) any conditional rule of action, concerned with means and ends rather than with duty for its own sake
  • in sack cloth and ashes — sacking.
  • industrial psychologist — a person who studies human behaviour and cognitive processes in relation to the working environment
  • interchange file format — (file format)   (IFF, full name "EA IFF 1985") A generic file format published by Electronic Arts as an open standard. IFF is chunk-based and hierarchical so files can include other files. It is easily extensible and an all round Good Idea. An IFF file starts with one of the following "group IDs": 'FORM', 'LIST' or 'CAT '. This is followed by an unsigned 32-bit number of bytes in the remainder of the file. Then comes an ID that indicates which type of IFF file this is. The main image type is ILBM, audio is either AIFF or 8SVX, animations are ANIM etc. An IFF file will probably have a filename extension related to this file type stored in the file. The rest of the file is divided into chunks each of which also has a four-byte header and byte count.
