  • communications software — (communications, software)   Application programs, operating system components, and probably firmware, forming part of a communication system. These different software components might be classified according to the functions within the Open Systems Interconnect model which they provide. Typical applications include a web browser, Mail User Agent, chat and telnet.
  • communist international — Third International.
  • communist-international — an international organization (1919–43), founded in Moscow, uniting Communist groups of various countries and advocating the attainment of their ends by violent revolution. Also called Comintern, Communist International. Compare international (def 6).

  • computer-based training — Computer-Aided Instruction
  • concertgebouw orchestra — an Amsterdam orchestra, established in 1888, that has been independent of the Concertgebouw hall since World War II
  • concrete data structure — (theory)   (CDS) A model of programming language terms developed in the context of constructing fully abstract semantics for sequential languages. A CDS is a 4-tuple (C,V,E,|-) where C is a cell, V is a value, E is an event and |- is an "enabling relation". An event is a cell and a value. A cell C is "enabled" by a set of events S if S |- C. A state is a set of events which are consistent in that the values they give for any cell are all equal. Every cell in a state is enabled.
  • conditional convergence — the property of an infinite series that converges while the series formed by replacing each term in the given series with its absolute value diverges; the property of an infinite series that converges when the order of the terms is altered. Compare absolute convergence (def 1).
  • conditional probability — the probability of one event, A, occurring given that another, B, is already known to have occurred: written P(A|B) and equal to P(A and B)|P(B)
  • confessional television — television programmes, esp talk shows, in which members of the public reveal their private lives, personal problems, etc
  • conformational analysis — the study of the spatial arrangement of atoms or groups of atoms in a molecule and the way in which this influences chemical behaviour
  • conjunctive normal form — (logic)   (CNF) A logical formula consisting of a conjunction of disjunctions of terms where no disjunction contains a conjunction. Such a formula might also be described as a product of sums. E.g. the CNF of (A and B) or C is (A or C) and (B or C). Contrast Disjunctive Normal Form.
  • connection machine lisp — (language)   Lisp with a parallel data structure, the 'xapping', an array of values assigned to an array of sites.
  • conservative evaluation — (programming)   Under this parallel evaluation strategy, no evaluation is started unless it is known to be needed. The opposite of conservative evaluation is speculative evaluation.
  • consolidated deliveries — deliveries of goods to different shops in a common location by a single carrier and in a single vehicle
  • constant of gravitation — a law stating that any two masses attract each other with a force equal to a constant (constant of gravitation) multiplied by the product of the two masses and divided by the square of the distance between them.
  • constant of integration — a constant that is added to the function obtained by evaluating the indefinite integral of a given function, indicating that all indefinite integrals of the given function differ by, at most, a constant.
  • constant velocity joint — A constant velocity joint is a universal joint in which the output shaft rotates at constant speed if the input shaft speed is constant.
  • constant-velocity joint — a universal joint that is used in the drive train of front-wheel-drive cars and operates effectively even when the shafts being connected meet at a sharp angle.
  • constitutional monarchy — a monarchy governed according to a constitution that limits and defines the powers of the sovereign
  • constraint satisfaction — (application)   The process of assigning values to variables while meeting certain requirements or "constraints". For example, in graph colouring, a node is a variable, the colour assigned to it is its value and a link between two nodes represents the constraint that those two nodes must not be assigned the same colour. In scheduling, constraints apply to such variables as the starting and ending times for tasks. The Simplex method is one well known technique for solving numerical constraints. The search difficulty of constraint satisfaction problems can be determined on average from knowledge of easily computed structural properties of the problems. In fact, hard instances of NP-complete problems are concentrated near an abrupt transition between under- and over-constrained problems. This transition is analogous to phase transitions in physical systems and offers a way to estimate the likely difficulty of a constraint problem before attempting to solve it with search.
  • consultant psychiatrist — a psychiatrist who has attained the rank of consultant
  • conversion to iteration — A transformation applied to functional programs to replace recursion with iteration. A tail-recursive function can be compiled to an iterative loop where the recursive call becomes a jump back to the start and the parameters are held in registers which are updated with new values each time around the loop. See Iteration, Tail recursion optimisation.
  • cordillera de talamanca — a mountain range running SE from central Costa Rica to W Panama.
  • corporate restructuring — a change in the business strategy of an organization resulting in diversification, closing parts of the business, etc, to increase its long-term profitability
  • correlation coefficient — a statistic measuring the degree of correlation between two variables as by dividing their covariance by the square root of the product of their variances. The closer the correlation coefficient is to 1 or –1 the greater the correlation; if it is random, the coefficient is zero
  • correlative conjunction — either member of a matched pair of words, of which the second is a coordinating conjunction, as either … or, neither … nor, both … and, or not only … but.
  • corridor of uncertainty — an area of a wicket just outside a batsman's off stump, so located that the batsman will have difficulty in deciding whether or not to play a ball bowled into it
