  • clockwork precision — regularity
  • collision detection — (networking)   A class of methods for sharing a data transmission medium in which hosts transmit as soon as they have data to send and then check to see whether their transmission has suffered a collision with another host's. If a collision is detected then the data must be resent. The resending algorithm should try to minimise the chance that two hosts's data will repeatedly collide. For example, the CSMA/CD protocol used on Ethernet specifies that they should then wait for a random time before re-transmitting. See also backoff. This contrasts with slotted protocols and token passing.
  • command line option — (software)   (Or "option", "flag", "switch", "option switch") An argument to a command that modifies its function rather than providing data. Options generally start with "-" in Unix or "/" in MS-DOS. This is usually followed by a single letter or occasionally a digit. More recently, GNU software adopted the --longoptionname style, usually in addition to traditional, single-character, -x style equivalents. Some commands require each option to be a separate argument, introduced by a new "-" or "/", others allow multiple option letters to be concatenated into a single argument with a single "-" or "/", e.g. "ls -al". A few Unix commands (e.g. ar, tar) allow the "-" to be omitted. Some options may or must be followed by a value, e.g. "cc prog.c -o prog", sometimes with and sometimes without an intervening space.
  • community education — the provision of a wide range of educational and special interest courses and activities by a local authority
  • complement fixation — the fixing of complement into the product of an antigen-antibody reaction: used as an infection indicator in certain serologic tests that measure the presence or absence of free, active complement
  • compromise solution — a solution to a problem reached by compromise
  • computer simulation — an event, process, or scenario that is created on a computer
  • consumer protection — laws and policies designed to protect consumers against unfair trade and credit practices
  • contagious abortion — brucellosis of domestic cattle, an infectious disease characterized by spontaneous abortion and caused by the bacterium Brucella abortus; Bang's disease.
  • continued education — adult education.
  • continuity equation — the mathematical statement in fluid mechanics that, for a fluid passing through a tube in a steady flow, the mass flowing through any section of the tube in a unit of time is constant.
  • continuous creation — the theory that matter is being created continuously in the universe
  • continuous function — (loosely) a mathematical function such that a small change in the independent variable, or point of the domain, produces only a small change in the value of the function.
  • contour integration — integration in the complex plane about a closed curve of finite length.
  • conventional weapon — a nonnuclear weapon.
  • conventionalization — to make conventional.
  • cosmopolitanization — to make cosmopolitan.
  • cost-push inflation — inflation in which prices increase as a result of increased production costs, as labor and parts, even when demand remains the same.
  • counter reformation — the movement within the Roman Catholic Church that followed the Protestant Reformation of the 16th century.
  • counter-proposition — a proposition made in place of or in opposition to a preceding one.
  • counter-reformation — the reform movement of the Roman Catholic Church in the 16th and early 17th centuries considered as a reaction to the Protestant Reformation
  • cracked compression — Cracked compression is a separation process for separating hydrocarbons further, with an increase in the pressure of the cracked gas.
  • craters of the moon — a national monument in S Idaho: site of scenic lava-flow formations.
  • cross-fertilization — fertilization by the fusion of male and female gametes from different individuals of the same species
  • cultural revolution — (in China) a mass movement (1965–68), in which the youthful Red Guard played a prominent part. It was initiated by Mao Tse-tung to destroy the power of the bureaucrats and to revolutionize the attitudes and behaviour of the people
  • customs declaration — a form declaring the nature and value of goods, etc, for customs purposes
  • dance attendance on — to be always near so as to wait on, lavish attention on, etc.
  • de broglie equation — the postulate of wave mechanics that a particle of mass m moving at a velocity v will have the properties of a wave of wavelength h / mv (de Broglie wavelength) where h is Planck's constant.
  • deathbed confession — a confession that somebody makes just before he or she dies, usually relating to some long concealed crime or secret
  • decontextualization — to remove (a linguistic element, an action, etc.) from a context: decontextualized works of art displayed in museums.
  • deflate compression — deflate
  • deindustrialisation — Alternative spelling of deindustrialization.
  • deindustrialization — the decline in importance of manufacturing industry in the economy of a nation or area
  • departmentalisation — Alternative spelling of departmentalization.
  • departmentalization — to divide into departments.
  • diamond-point spoon — a spoon having a handle terminating in a polygonal, pointed knob.
  • difference equation — (mathematics)   A relation between consecutive elements of a sequence. The first difference is D u(n) = u(n+1) - u(n) where u(n) is the nth element of sequence u. The second difference is u(n+2) + a u(n+1) + b u(n) = 0 can be converted to a difference equation (in this case, a second order linear difference equation): D2 u(n) + p D u(n) + q u(n) = 0 and vice versa. a, b, p, q are constants.
  • dimetric projection — a type of axonometric projection in which the object is shown with two of its three principal axes tilted equally from the plane of viewing
  • disciplinary action — punishment or caution
  • discriminated union — (theory)   The discriminated union of two sets A and B is A + B = {(inA, a) | a in A} U {(inB, b)| b in B} where inA and inB are arbitrary tags which specify which summand an element originates from. A type (especially an algebraic data type) might be described as a discriminated union if it is a sum type whose objects consist of a tag to say which part of the union they belong to and a value of the corresponding type.
  • dispersion relation — the relationship between the angular frequency (ω;) of a wave and the magnitude of its wave vector (k). Thus the wave's speed is ω/k
  • draw the curtain on — to end
  • dred scott decision — Barbara Ann, 1928–2012, Canadian figure skater.
  • dynamic translation — (architecture)   A virtual machine implementation approach, used to speed up execution of byte-code programs. To execute a program unit such as a method or a function, the virtual machine compiles its bytecodes into (hardware) machine code. The translated code is also placed in a cache, so that next time that unit's machine code can be executed immediately, without repeating the translation. This technique was pioneered by the commercial Smalltalk implementation currently known as VisualWorks, in the early 1980s. Currently it is also used by some implementations of the Java Virtual Machine under the name JIT (Just In Time compilation).
  • elastic deformation — In elastic deformation a material changes shape when a stress is applied to it but goes back to its original state when the stress is removed.
  • electro-shock baton — a baton used as a weapon to pass an electric current through part of the body
  • electronic ignition — any system that uses an electronic circuit to supply the voltage to the sparking plugs of an internal-combustion engine
  • end of transmission — (character)   (EOT) The mnemonic for ASCII character 4.
  • end-to-end solution — (jargon)   (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved. Compare: turn-key solution.
  • energy conservation — concerted formal or government action or policy to make sure that energy is not wasted
