  • díaz del castillo, bernal — (bɛʀˈnɑl) ; bernälˈ) 1492?-1581?; Sp. historian & soldier with Cortés
  • diesel-electric generator — A diesel-electric generator is a piece of equipment that uses diesel as a fuel to produce electricity.
  • digital rights management — (legal)   (DRM) Any technology used to limit the use of software, music, movies or other digital data. This generally relies on some interaction between the media and the system that plays it. For example, video DVDs usually include a region code. If this does not match the player's region code, the player will refuse to play the disc.
  • digital signal processing — (DSP) Computer manipulation of analog signals (commonly sound or image) which have been converted to digital form (sampled).
  • diminished responsibility — law: lack of capacity
  • discrete cosine transform — (mathematics)   (DCT) A technique for expressing a waveform as a weighted sum of cosines. The DCT is central to many kinds of signal processing, especially video compression. Given data A(i), where i is an integer in the range 0 to N-1, the forward DCT (which would be used e.g. by an encoder) is: B(k) = sum A(i) cos((pi k/N) (2 i + 1)/2) i=0 to N-1 B(k) is defined for all values of the frequency-space variable k, but we only care about integer k in the range 0 to N-1. The inverse DCT (which would be used e.g. by a decoder) is: AA(i)= sum B(k) (2-delta(k-0)) cos((pi k/N)(2 i + 1)/2) k=0 to N-1 where delta(k) is the Kronecker delta. The main difference between this and a discrete Fourier transform (DFT) is that the DFT traditionally assumes that the data A(i) is periodically continued with a period of N, whereas the DCT assumes that the data is continued with its mirror image, then periodically continued with a period of 2N. Mathematically, this transform pair is exact, i.e. AA(i) == A(i), resulting in lossless coding; only when some of the coefficients are approximated does compression occur. There exist fast DCT algorithms in analogy to the Fast Fourier Transform.

  • 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.

  • extended backus-naur form — (language)   Any variation on the basic Backus-Naur Form (BNF) meta-syntax notation with (some of) the following additional constructs: square brackets "[..]" surrounding optional items, suffix "*" for Kleene closure (a sequence of zero or more of an item), suffix "+" for one or more of an item, curly brackets enclosing a list of alternatives, and super/subscripts indicating between n and m occurrences. All these constructs can be expressed in plain BNF using extra productions and have been added for readability and succinctness.

  • 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.

  • graphic design department — a group of people in a company who work in graphic design
  • graphic display interface — (hardware)   (GDI) graphics adaptor.
  • group-sweeping scheduling — (storage, algorithm)   (GSS) A disk scheduling strategy in which requests are served in cycles, in a round-robin manner. To reduce disk arm movements ("seeking"), the set of streams is divided into groups that are served in fixed order. Streams within a group are served according to "SCAN". If all clients are assigned to one group, GSS reduces to SCAN, and if all clients are assigned to separate groups, GSS effectively becomes round-robin scheduling. The service order within one group is not fixed, and a stream may in fact be first in one cycle while last in the next. This variation has to be masked by extra buffering but whereas SCAN requires buffer space for all streams, GSS can reuse the buffer for each group and effect a trade-off between seek optimisation and buffer requirements.
