  • 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.
  • extravehicular activity — the act or an instance of floating and manoeuvring in space, outside but attached by a lifeline to a spacecraft
  • 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.
  • ferric ammonium oxalate — a green, crystalline, water-soluble, synthetically produced powder, (NH 4) 3 Fe(C 2 O 4) 3 ⋅3H 2 O, used chiefly in the manufacture of blueprint paper.
  • fetal tissue transplant — a surgical procedure in which tissue from an aborted fetus is grafted into a patient to replace or improve defective tissue, especially to treat Parkinson's disease or other neurological disorders.
  • fifth marquis lansdowneHenry Charles Keith, 5th Marquis of Lansdowne, Lansdowne, 5th Marquis of.
  • fish in troubled waters — any of various cold-blooded, aquatic vertebrates, having gills, commonly fins, and typically an elongated body covered with scales.
  • 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).
  • friction reducing agent — A friction reducing agent is an additive used to reduce friction exerted downhole on tools and pipes.
  • frictional unemployment — those people who are in the process of moving from one job to another and who therefore appear in the unemployment statistics collected at any given time
  • 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.
  • function point analysis — (programming)   (FPA) A standard metric for the relative size and complexity of a software system, originally developed by Alan Albrecht of IBM in the late 1970s. Functon points (FPs) can be used to estimate the relative size and complexity of software in the early stages of development - analysis and design. The size is determined by identifying the components of the system as seen by the end-user: the inputs, outputs, inquiries, interfaces to other systems, and logical internal files. The components are classified as simple, average, or complex. All of these values are then scored and the total is expressed in Unadjusted FPs (UFPs). Complexity factors described by 14 general systems characteristics, such as reusability, performance, and complexity of processing can be used to weight the UFP. Factors are also weighted on a scale of 0 - not present, 1 - minor influence, to 5 - strong influence. The result of these computations is a number that correlates to system size. Although the FP metric doesn't correspond to any actual physical attribute of a software system (such as lines of code or the number of subroutines) it is useful as a relative measure for comparing projects, measuring productivity, and estimating the amount a development effort and time needed for a project. See also International Function Point Users Group.
  • functional requirements — (specification)   What a system should be able to do, the functions it should perform. This term is used at both the user requirements analysis and software requirements specifications phases in the software life-cycle. An example of a non-functional requirement is an initialisation sequence incorporated into the software that is specific to a given customer.
  • fundamental interaction — any of the four basic interactions that occur in nature: the gravitational, electromagnetic, strong, and weak interactions
  • gamma-aminobutyric acid — GABA.
  • garbage in, garbage out — (humour)   (GIGO) /gi:'goh/ Wilf Hey's maxim expressing the fact that computers, unlike humans, will unquestioningly process nonsensical input data and produce nonsensical output. Of course a properly written program will reject input data that is obviously erroneous but such checking is not always easy to specify and is tedious to write. GIGO is usually said in response to lusers who complain that a program didn't "do the right thing" when given imperfect input or otherwise mistreated in some way. Also commonly used to describe failures in human decision making due to faulty, incomplete, or imprecise data. The expansion "Garbage In, Gospel Out" is an ironic comment on the tendency to put excessive trust in "computerised" data.
  • gastroesophageal reflux — a chronic condition in which acid from the stomach flows back into the lower esophagus, causing pain or tissue damage.
  • german southwest africa — a former name of Namibia.
