  • experimental psychology — the scientific study of the individual behaviour of man and other animals, esp of perception, learning, memory, motor skills, and thinking
  • extended graphics array — (hardware)   (XGA) An IBM display standard introduced in 1990. XGA supports a resolution of 1024 x 768 pixels with a palette of 256 colours, or 640 x 480 with high colour (16 bits per pixel). XGA-2 added 1024 x 768 support for high colour and higher refresh rates, improved performance, and supports 1360 x 1024 in 16 colours. XGA is probably not the same as 8514-A. See also VESA's EVGA released at a similar time.

  • 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
  • fractional distillation — the separation of volatile components of different boiling points in a mixture by the gradual increase of temperature and the separate collection of each component.

  • friedel-crafts reaction — a reaction for the synthesis of hydrocarbons and ketones by the alkylation or acylation of an aromatic compound in the presence of a catalyst, typically anhydrous aluminum chloride.
  • frozen food compartment — a compartment of a refrigerator or fridge-freezer for the storage of frozen food
  • 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.

  • 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.
