  • creeping bent grass — a grass, Agrostis stolonifera, grown as a pasture grass in Europe and North America: roots readily from the stem
  • creeping featuritis — (jargon)   /kree'ping fee'-chr-i:`t*s/ A variant of creeping featurism, with its own spoonerism: "feeping creaturitis". Some people like to reserve this form for the disease as it actually manifests in software or hardware, as opposed to the lurking general tendency in designers' minds. -ism means "condition" or "pursuit of", whereas -itis usually means "inflammation of".
  • cuboidal epithelium — epithelium consisting of one or more layers of cells of cuboid or polyhedral shape.
  • cult of personality — a cult promoting adulation of a living national leader or public figure, as one encouraged by Stalin to extend his power.
  • dangling participle — a participle intended to modify a noun but having the wrong grammatical relationship to it as for example having left in the sentence Having left Europe for good, Peter's future seemed bleak indeed
  • data encryption key — (DEK) Used for the encryption of message text and for the computation of message integrity checks (signatures). See cryptography.
  • data protection act — (legal)   (DPA) A UK law guaranteeing rights to individuals in relation to personal data that others hold on them. For example, under the DPA, you have the right to see what data a company holds on you.
  • de-compartmentalize — to divide into categories or compartments.
  • deaf without speech — (usually of a prelingually deaf person) able to utter sounds but not speak
  • deflate compression — deflate
  • dental receptionist — a receptionist working in a dental surgery

  • descriptive grammar — an approach to grammar that is concerned with reporting the usage of native speakers without reference to proposed norms of correctness or advocacy of rules based on such norms.
  • differential backup — (operating system)   A kind of backup that copies all files that have changed since the last full backup. Each differential backup will include all files in previous differential backups since the full backup so to restore a version of a file, you only need to search the full backup and the relevant differential backup. Some systems support differential backup by associating an "Archive" flag with each file and setting this flag whenever the file is modified to indicate that it should be included in the next backup. A differential backup does not change this flag, whereas an incremental backup resets it.
  • diffraction pattern — the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.
  • diplomatic immunity — exemption from taxation, searches, arrest, etc., enjoyed by diplomatic officials and their dependent families under international law, and usually on a reciprocal basis.
  • direct mapped cache — (architecture)   A cache where the cache location for a given address is determined from the middle address bits. If the cache line size is 2^n then the bottom n address bits correspond to an offset within a cache entry. If the cache can hold 2^m entries then the next m address bits give the cache location. The remaining top address bits are stored as a "tag" along with the entry. In this scheme, there is no choice of which block to flush on a cache miss since there is only one place for any block to go. This simple scheme has the disadvantage that if the program alternately accesses different addresses which map to the same cache location then it will suffer a cache miss on every access to these locations. This kind of cache conflict is quite likely on a multi-processor. See also fully associative cache, set associative cache.
  • directional coupler — (communications)   (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps).
  • disaster capitalism — the practice (by a government, regime, etc) of taking advantage of a major disaster to adopt liberal economic policies that the population would be less likely to accept under normal circumstances
  • disciplinary action — punishment or caution
  • dispatch department — the department of an organization responsible for the dispatch of orders
  • displacement engine — any engine employing the rectilinear motion of one or more pistons in cylinders.
  • dobsonian telescope — a relatively inexpensive Newtonian telescope, suitable for visual but not photographic use, in which the tube assembly slips freely in the lower base.
  • duplicating machine — a duplicator, especially one for making identical copies of documents, letters, etc.
  • dynamic positioning — Dynamic positioning is the use of computers to control the position of a semi-submersible rig.
  • electrocardiographs — Plural form of electrocardiograph.
  • electrocardiography — The measurement of electrical activity in the heart and the recording of such activity as a visual trace (on paper or on an oscilloscope screen), using electrodes placed on the skin of the limbs and chest.
  • electrode potential — the potential difference developed when an electrode of an element is placed in a solution containing ions of that element
  • electron micrograph — a photograph or image of a specimen taken using an electron microscope
  • electronic graphics — (on television) the production of graphic designs and text by electronic means
  • electrophoretically — By means of electrophoresis.
  • electrophotographic — Of or pertaining to electrophotography.
  • electrotherapeutics — (medicine) the use of electricity in therapeutics.
  • elementary particle — any of several entities, such as electrons, neutrons, or protons, that are less complex than atoms and are regarded as the constituents of all matter
  • evaporative cooling — a method of reducing temperature that uses evaporation
  • exophthalmic goiter — a disease of unknown cause characterized by enlargement of the thyroid gland, overproduction of the thyroid hormone, and abnormal protrusion of the eyeballs
  • exophthalmic goitre — a form of hyperthyroidism characterized by enlargement of the thyroid gland, protrusion of the eyeballs, increased basal metabolic rate, and weight loss

  • genetic programming — (programming)   (GP) A programming technique which extends the genetic algorithm to the domain of whole computer programs. In GP, populations of programs are genetically bred to solve problems. Genetic programming can solve problems of system identification, classification, control, robotics, optimisation, game playing, and pattern recognition. Starting with a primordial ooze of hundreds or thousands of randomly created programs composed of functions and terminals appropriate to the problem, the population is progressively evolved over a series of generations by applying the operations of Darwinian fitness proportionate reproduction and crossover (sexual recombination).
  • geocentric parallax — the apparent displacement of an observed object due to a change in the position of the observer.
  • gigabits per second — (unit)   (Gbps) A unit of information transfer rate equal to one billion bits per second. Note that, while a gigabit is defined as a power of two (2^30 bits), a gigabit per second is defined as a power of ten (10^9 bits per second, which is slightly less) than 2^30).
