- dictionary of names — a dictionary of given names that indicates whether a name is usually male, female, or unisex and often includes origins as well as meanings; for example, as by indicating that Evangeline, meaning “good news,” comes from Greek. Used primarily as an aid in selecting a name for a baby, dictionaries of names may also include lists of famous people who have shared a name and information about its current popularity ranking.
- 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.

- diffraction pattern — the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.

- disciples of christ — a Christian denomination, founded in the U.S. by Alexander Campbell in the early part of the 19th century, that rejects all creeds, holds the Bible as a sufficient rule of faith and practice, administers baptism by immersion, celebrates the Lord's Supper every Sunday, and has a congregational polity.

- ferrite core memory — (storage) (Or "core") An early form of non-volatile storage built (by hand) from tiny rings of magnetisable material threaded onto very fine wire to form large (e.g. 13"x13" or more) rectangluar arrays. Each core stored one bit of data. These were sandwiched between printed circuit boards(?). Sets of wires ran horizontally and vertically and where a vertical and horizontal wire crossed, a core had both wires threaded through it. A single core could be selected and magnetised by passing sufficient current through its horizontal and vertical wires. A core would retain its magnetisation until it was re-magnetised. The two possible polarities of magnetisation were used to represent the binary values zero and one. A third "sense" wire, passed through the core and, if the magnetisation of the core was changed, a small pulse would be induced in the sense wire which could be detected and used to deduce the core's original state. Some core memory was immersed in a bath of heated oil to improve its performance. Core memory was rendered obsolete by semiconductor memory. For example, the 1970s-era NCR 499 had two boards, each with 16 kilobytes of core memory.
