- aarp probe packets — (networking) AARP packets sent out on a nonextended AppleTalk network to discover whether a randomly selected node ID is being used by any node. If not, the sending node uses the node ID. If so, it chooses a different ID and sends more AARP probe packets.

- assignment problem — (mathematics, algorithm) (Or "linear assignment") Any problem involving minimising the sum of C(a, b) over a set P of pairs (a, b) where a is an element of some set A and b is an element of set B, and C is some function, under constraints such as "each element of A must appear exactly once in P" or similarly for B, or both. For example, the a's could be workers and the b's projects. The problem is "linear" because the "cost function" C() depends only on the particular pairing (a, b) and is independent of all other pairings.
- before the present — See B.P (def 4).
- bichromate process — any of several methods of photography in which the light-sensitive medium is alkaline bichromate associated with a colloid such as gum, albumen, or gelatin.

- centre of pressure — the point in a body at which the resultant pressure acts when the body is immersed in a fluid

- compressor station — A compressor station is a facility with several compressors (= devices that increase the pressure of air or natural gas) and other equipment to pump natural gas under pressure over long distances.
- conjugated protein — a biochemical compound consisting of a sequence of amino acids making up a simple protein to which another nonprotein group (a prosthetic group), such as a carbohydrate or lipid group, is attached
- constructive proof — (mathematics) A proof that something exists that provides an example or a method for actually constructing it. For example, for any pair of finite real numbers n < 0 and p > 0, there exists a real number 0 < k < 1 such that f(k) = (1-k)*n + k*p = 0. A constructive proof would proceed by rearranging the above to derive an equation for k: k = 1/(1-n/p) From this and the constraints on n and p, we can show that 0 < k < 1. A few mathematicians actually reject *all* non-constructive arguments as invalid; this means, for instance, that the law of the excluded middle (either P or not-P must hold, whatever P is) has to go; this makes proof by contradiction invalid. See intuitionistic logic. Constructive proofs are popular in theoretical computer science, both because computer scientists are less given to abstraction than mathematicians and because intuitionistic logic turns out to be an appropriate theoretical treatment of the foundations of computer science.
- continuous process — A continuous process is a process in which the product comes out without interruption and not in groups.
- counter-productive — Something that is counter-productive achieves the opposite result from the one that you want to achieve.
- counterprogramming — the practice of scheduling a program opposite another program, esp. a popular one, that appeals to a different kind of audience, as in placing a romantic film directed at women opposite a sports program mainly watched by men

- criminal profiling — the analysis of a person's psychological and behavioural characteristics, so as to assess whether they are likely to have committed a crime under investigation
- currency principle — the principle that banks should be permitted to issue notes only against bullion or coin.
- daisywheel printer — (printer) A kind of impact printer where the characters are arranged on the ends of the spokes of a wheel (resembling the petals on a daisy). The wheel (usually made of plastic) is rotated to select the character to print and then an electrically operated hammer mechanism bends the selected spoke forward slightly, sandwiching an ink ribbon between the character and the paper, as in a typewriter. One advantage of this arrangement over that of a typewriter is that different wheels may be inserted to produce different typefaces.
- decision procedure — a procedure, as an algorithm, for determining in a finite number of steps the validity of any of a certain class of propositions.
- discharge printing — a fabric-printing method in which the material is dyed and then certain areas are discharged so as to permit the original hue or its color replacement to act as a pattern against the colored ground.
- disproportionality — not in proportion; disproportionate.
- disproportionately — not proportionate; out of proportion, as in size or number.
- disproportionation — the simultaneous oxidation and reduction of a substance reacting with itself, thereby forming two dissimilar molecules, as 2C 2 H 4 →C 2 H 6 +C 2 H 2 .
- dna fingerprinting — the use of a DNA probe for the identification of an individual, as for the matching of genes from a forensic sample with those of a criminal suspect.
- dot matrix printer — (hardware, printer) A kind of printer with a vertical column of up to 48 small closely packed needles or "pins" each of which can be individually forced forward to press an ink ribbon against the paper. The print head is repeatedly scanned across the page and different combinations of needles activated at each point. Dot matrix printers are noisy compared to non-impact printers.
- dot-matrix printer — device: prints using matrix dots
- double-page spread — two pages treated as one in a publication, with images or text extending across the binding
- due process of law — the administration of justice in accordance with established rules and principles
- ejaculatio praecox — premature ejaculation during sexual intercourse
