- command line interface — (operating system) A means of communication between a program and its user, based solely on textual input and output. Commands are input with the help of a keyboard or similar device and are interpreted and executed by the program. Results are output as text or graphics to the terminal. Command line interfaces usually provide greater flexibility than graphical user interfaces, at the cost of being harder for the novice to use. Consequently, some hackers look down on GUIs as designed For The Rest Of Them.

- dalton's atomic theory — the theory that matter consists of indivisible particles called atoms and that atoms of a given element are all identical and can neither be created nor destroyed. Compounds are formed by combination of atoms in simple ratios to give compound atoms (molecules). The theory was the basis of modern chemistry
- dandie dinmont terrier — any of a breed of small terrier with short legs, drooping ears, and a generally rough coat with a mass of silky hair on top of the head
- data address generator — (architecture) (DAG) The mechanism which generates temporary memory addresses for data that is transferred between memory and registers in a Digital Signal Processor. Certain DSP architectures incorporate more than one DAG to simplify the programming needed to move blocks of data between buffers. For instance, certain Fast Fourier Transform algorithms requiring bit reversing, can use the DAG for that purpose, or they can use two DAGS, one for Program Memory Data (PMD), and the other for Data Memory Data (DMD).
- database administrator — (job) A person responsible for the design and management of one or more databases and for the evaluation, selection and implementation of database management systems. In smaller organisations, the data administrator and database administrator are often one in the same; however, when they are different, the database administrator's function is more technical. The database administrator would implement the database software that meets the requirements outlined by the organisation's data administrator and systems analysts. Tasks might include controling an organisation's data resources, using data dictionary software to ensure data integrity and security, recovering corrupted data and eliminating data redundancy and uses tuning tools to improve database performance.
- database normalisation — (database) A series of steps followed to obtain a database design that allows for efficient access and storage of data in a relational database. These steps reduce data redundancy and the chances of data becoming inconsistent. A table in a relational database is said to be in normal form if it satisfies certain constraints. Codd's original work defined three such forms but there are now five generally accepted steps of normalisation. The output of the first step is called First Normal Form (1NF), the output of the second step is Second Normal Form (2NF), etc. First Normal Form eliminates repeating groups by putting each value of a multi-valued attribute into a new row. Second Normal Form eliminates functional dependencies on a partial key by putting the fields in a separate table from those that are dependent on the whole key. Third Normal Form eliminates functional dependencies on non-key fields by putting them in a separate table. At this stage, all non-key fields are dependent on the key, the whole key and nothing but the key. Fourth Normal Form separates independent multi-valued facts stored in one table into separate tables. Fifth Normal Form breaks out data redundancy that is not covered by any of the previous normal forms.
- days of wine and roses — a period of happiness and prosperity.
- de broglie wave length — 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.
- decompartmentalization — the act of decompartmentalizing
- decompression sickness — a disorder characterized by severe pain in muscles and joints, cramp, and difficulty in breathing, caused by a sudden and sustained decrease in air pressure, resulting in the deposition of nitrogen bubbles in the tissues
- dehydroepiandrosterone — the most abundant steroid in the human body, that is involved in the manufacture of testosterone, oestrogen, progesterone, and corticosterone
- delaunay triangulation — (mathematics, graphics) (After B. Delaunay) For a set S of points in the Euclidean plane, the unique triangulation DT(S) of S such that no point in S is inside the circumcircle of any triangle in DT(S). DT(S) is the dual of the voronoi diagram of S.
- delayed-action shutter — a camera shutter that opens after an interval set by the photographer
- deoxyribonucleoprotein — any of a class of nucleoproteins that yield DNA upon partial hydrolysis.
- department of commerce — the department of the U.S. federal government that promotes and administers domestic and foreign commerce. Abbreviation: DOC.
- descriptive cataloging — the aspect of cataloging concerned with the bibliographic and physical description of a book, recording, or other work, accounting for such items as author or performer, title, edition, and imprint as opposed to subject content.
- developmental disorder — any condition, such as autism or dyslexia, that appears in childhood and is characterized by delay in the development of one or more psychological functions, such as language skill
- diachronic linguistics — historical linguistics.
- dicyclopentadienyliron — ferrocene (def 1).
- digital control system — (systems) (DCS) A digital computer used for real-time control of a dynamic system, usually in an industrial environment, possibly as part of a Supervisory Control and Data Acquisition (SCADA) system. A DCS samples feedback from the system under control and modifies the control signals in an attempt to achieve some desired behaviour. Analysis of such digital-analogue feedback systems can involve mathematical methods such as difference equations, Laplace transforms, z transfer functions, state space models and state transition matrices.
- digital radio mondiale — (communications) (DRM) A form of monaural digital broadcast using carrier frequencies below 30 MHz. DRM uses MPEG-4 AAC Main Profile and SBR at data rates of 16-25 kbps.
