- 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.
- constructive cost model — (programming) (COCOMO) A method for estimating the cost of a software package, proposed by Dr Barry Boehm. The Basic COCOMO Model estimates the effort required to develop software in three modes of development (Organic Mode, Semidetached Mode, or Embedded Mode) using only DSIs as an input. The Basic model is good for quick estimates. The Intermediate Model extends the Basic Model with an Effort Adjustment Factor (EAF) and different coefficients for the effort equation. The user supplies settings for cost drivers that determine the effort and duration of the software projects. It also allows DSI values and cost drivers to be chosen for individual components instead of for the system as a whole. The Detailed COCOMO Model uses effort multipliers for each phase of the project and provides a three-level product hierarchy and has some other capabilities such as a procedure for adjusting the phase distribution of the development schedule.

- data terminal equipment — (communications, hardware) (DTE) A device which acts as the source and/or destination of data and which controls the communication channel. DTE includes terminals, computers, protocol converters, and multiplexors. DTE is usually connected via an EIA-232 serial line to Data Communication Equipment (DCE), typically a modem. It is necessary to distinguish these two types of device because their connectors must be wired differently if a "straight-through" cable (pin 1 to pin 1, pin 2 to pin 2 etc.) is to be used. DTE should have a male connector and should transmit on pin three and receive on pin two. It is a curious fact that many modems are actually "DTE" according to the original standard.

- deterministic automaton — (theory) A finite-state automaton in which the overall course of the computation is completely determined by the program, the starting state, and the initial inputs. The class of problems solvable by such automata is the class P (see polynomial-time algorithm).
- development environment — (programming, tool) An integrated suite of tools to aid the development of software in a particular language or for a particular application. Usually, this consists of a compiler and editor and may also include one or more of a debugger, profiler, and source code manager. See also: IDE.

- discrimination learning — a learning process in which an organism learns to react differently to different stimuli
- disjunctive normal form — (DNF) A logical formula consisting of a disjunction of conjunctions where no conjunction contains a disjunction. E.g. the DNF of (A or B) and C is (A and C) or (B and C).
- dissociate oneself from — to deny or repudiate any connection with
- do someone's dirty work — To do someone's dirty work means to do a task for them that is dishonest or unpleasant and which they do not want to do themselves.

- dual sensory impairment — the condition of being affected by sight and hearing loss
- electronic mail address — (messaging) (Usually "e-mail address") The string used to specify the source or destination of an electronic mail message. E.g. "[email protected]". The RFC 822 standard is probably the most widely used on the Internet. X.400 was once used in Europe and Canada. UUCP-style (bang path) addresses or other kinds of source route became virtually extinct in the 1990s. In the example above, "john" is the local part which is the name of a mailbox on the destination computer. If the sender and recipient use the same computer, or the same LAN, for electronic mail then the local part is usually all that is required. If they use different computers, e.g. they work at different companies or use different Internet service providers, then the "host part", e.g. "sales.acme.com" must be appended after an "@". This usually takes the form of a fully qualified domain name or, within a large organisation, it may be just the hostname part, e.g. "sales". The destination computer named by the host part is usually a server of some kind rather than an individual's workstation or PC. The user's mail is stored on the server and read later via client mail software running on the user's computer. Large organisations, such as universities will often set up a global alias directory which maps a simple user name such as "jsmith" to an address which contains more information such as "[email protected]". This hides the detailed knowledge of where the message will be delivered from the sender, making it much easier to redirect mail if a user leaves or moves to a different department for example.
- eliminative materialism — (in philosophy of mind) the theory that people's common-sense understanding of the mind is false and that certain classes of mental states that most people believe in do not exist
- embarrassment of riches — If you say that someone has an embarrassment of riches, you mean that they have so many good things that these things are a problem.

- error correcting memory — (storage) (ECM) RAM using some kind of error detection and correction (EDAC) scheme. The two types of memory errors in RAM (especially DRAM) are "soft" errors due to radiation-induced bit switching, and "hard" errors due to the unexpected deterioration of a memory chip. Soft errors do not indicate lasting damage to the memory board, but they do corrupt programs or data. Hard errors demand physical repairs. Single bit memory failures are the most common. A hard single bit failure, such as that caused by a completely dead chip can be corrected by EDAC if each chip supplies only one bit of each word. EDAC memory is the most common level of protection for minicomputers and mainframes whereas the cheaper parity protection is more common in microcomputers.
