  • entity-relationship model — (database, specification)   An approach to data modelling proposed by P. Chen in 1976. The model says that you divide your database in two logical parts, entities (e.g. "customer", "product") and relations ("buys", "pays for"). One of the first activities in specifying an application is defining the entities involved and their relationships, e.g. using an entity-relationship diagram to represent a model.
  • exhaust gas recirculation — Exhaust gas recirculation is the process of mixing exhaust gas with air taken in to make sure that all fuel is burned before entering the atmosphere.
  • exploratory data analysis — (EDA)
  • extended fortran language — (EFL) A Fortran preprocessor to provide structured programming constructs much like C. EFL is a descendant of RATFOR. It is written in C.
  • exterior gateway protocol — (EGP) A protocol which distributes routing information to the routers which connect autonomous systems. The term "gateway" is historical, and "router" is currently the preferred term. There is also a routing protocol called EGP defined in STD 18, RFC 904. See also Border Gateway Protocol, Interior Gateway Protocol.
  • fallacy of many questions — the rhetorical trick of asking a question that cannot be answered without admitting a presupposition that may be false, as have you stopped beating your wife?
  • federal capital territory — former name of Australian Capital Territory.
  • female genital mutilation — the practice observed in some cultures of removing part or all of a woman's or girl's genitalia
  • fifth generation language — (language, artificial intelligence)   A myth the Japanese spent a lot of money on. In about 1982, MITI decided it would spend ten years and a lot of money applying artificial intelligence to programming, thus solving the software crisis. The project spent its money and its ten years and in 1992 closed down with a wimper.
  • first generation language — Raw machine code. When computers were first "programmed" from an input device, rather than by being rewired, they were fed input in the form of numbers, which they then interpreted as commands. This was really low level, and a program fragment might look like "010307 010307". Almost no one programs in machine language anymore, because translators are nearly trivial to write.
  • flash lights impressively — (programming, humour)   (FLI) /FLY/ A joke assembly language instruction first documented in the late 1970s in "The Hackers Dictionary". The FLI instruction was frequently referred to by engineers when minicomputers such as the DEC PDP-8, PDP-11 and some early microcomputers such as the IMSAI and Altair had dozens of front panel lights. "When the computer is about to do some long I/O operation, stick in a FLI so the accountants won't think the machine has hung again."
  • flexible spending account — an account to which an employee contributes a portion of earnings to pay for certain expenses such as medical and dependent care: contributions are exempt from payroll taxes. Abbreviation: FSA.
  • flight management systems — a suite of computer programs in a computer on board an aircraft used to calculate the most economical flying speeds and altitudes during a flight and to identify possible choices in emergencies
  • free central placentation — a type of placenta structure in an ovary, in which the ovules cluster freely around a columnlike central placenta which is attached at the base of the ovary
  • frequently asked question — (convention)   (FAQ, or rarely FAQL, FAQ list) A document provided for many Usenet newsgroups (and, more recently, web services) which attempts to answer questions which new readers often ask. These are maintained by volunteers and posted regularly to the newsgroup. You should always consult the FAQ list for a group before posting to it in case your question or point is common knowledge. The collection of all FAQ lists is one of the most precious and remarkable resources on the Internet. It contains a huge wealth of up-to-date expert knowledge on many subjects of common interest. Accuracy of the information is greatly assisted by its frequent exposure to criticism by an interested, and occasionally well-informed, audience (the readers of the relevant newsgroup). The main FTP archive for FAQs is on a computer called RTFM at MIT, where they can be accessed either by group or by hierarchy. There is another archive at Imperial College, London, UK and a web archive in Ohio, USA. The FAQs are also posted to Usenet newsgroups: news:comp.answers, news:news.answers and news:alt.answers.
  • functional representation — representation in a governing body on the basis of social class or occupation.
  • further education college — (in Britain) an establishment that offers formal education beyond school and which is not a university or polytechnic
  • gabriel daniel fahrenheit — Gabriel Daniel [German gah-bree-el dah-nee-el] /German ˈgɑ briˌɛl ˈdɑ niˌɛl/ (Show IPA), 1686–1736, German physicist: devised a temperature scale and introduced the use of mercury in thermometers.
  • gas desulfurization plant — A gas desulfurization plant is a place with equipment that removes sulfur dioxide from flue gas before it is released into the atmosphere.
  • genealogical relationship — the relationship that exists between languages that have developed from a single earlier language.
  • general accounting office — an independent auditing and accounting agency that assists Congress and government departments and agencies and settles claims for the federal government. Abbreviation: GAO.
  • general recursion theorem — (mathematics)   Cantor's theorem, originally stated for ordinals, which extends inductive proof to recursive construction. The proof is by pasting together "attempts" (partial solutions).

  • guantánamo bay naval base — a US naval base on Guantánamo Bay; since 2002, a detainment camp for suspected al-Qaeda and Taliban operatives
  • gunning transceiver logic — (electronics, hardware, integrated circuit, standard)   (GTL) A standard for electrical signals in CMOS circuits used to provide higher data transfer speeds with smaller voltage swings [compared with what?]. The GTL signal swings between 0.4 volts and 1.2 volts with a reference voltage of about 0.8 volts. Only a small deviation of 0.4 volts (or thereabouts) from the reference voltage is required to switch between on and off states. Therefore, a GTL signal is said to be a low voltage swing logic signal. Gunning Transceiver Logic has several advantages. The resistive termination of a GTL signal provides a clean signalling environment [what?]. Moreover, the low terminating voltage of 1.2 volts results in reduced voltage drops across the resistive elements. GTL has low power dissipation and can operate at high frequency and causes less electromagnetic interference (EMI).
  • hailsham of st marylebone — Baron, title of Quintin (McGarel) Hogg (ˈkwɪntɪn). 1907–2001, British Conservative politician; Lord Chancellor (1970–74; 1979–87).

  • hypertext markup language — (hypertext, web, standard)   (HTML) A hypertext document format used on the web. HTML is built on top of SGML. "Tags" are embedded in the text. A tag consists of a "<", a "directive" (in lower case), zero or more parameters and a ">". Matched pairs of directives, like "" and "" are used to delimit text which is to appear in a special place or style. Links to other documents are in the form foo where "" and "" delimit an "anchor", "href" introduces a hypertext reference, which is most often a Uniform Resource Locator (URL) (the string in double quotes in the example above). The link will be represented in the browser by the text "foo" (typically shown underlined and in a different colour). A certain place within an HTML document can be marked with a named anchor, e.g.: The "fragment identifier", "baz", can be used in an href by appending "#baz" to the document name. Other common tags include

    for a new paragraph, .. for bold text,
