- discrete cosine transform — (mathematics) (DCT) A technique for expressing a waveform as a weighted sum of cosines. The DCT is central to many kinds of signal processing, especially video compression. Given data A(i), where i is an integer in the range 0 to N-1, the forward DCT (which would be used e.g. by an encoder) is: B(k) = sum A(i) cos((pi k/N) (2 i + 1)/2) i=0 to N-1 B(k) is defined for all values of the frequency-space variable k, but we only care about integer k in the range 0 to N-1. The inverse DCT (which would be used e.g. by a decoder) is: AA(i)= sum B(k) (2-delta(k-0)) cos((pi k/N)(2 i + 1)/2) k=0 to N-1 where delta(k) is the Kronecker delta. The main difference between this and a discrete Fourier transform (DFT) is that the DFT traditionally assumes that the data A(i) is periodically continued with a period of N, whereas the DCT assumes that the data is continued with its mirror image, then periodically continued with a period of 2N. Mathematically, this transform pair is exact, i.e. AA(i) == A(i), resulting in lossless coding; only when some of the coefficients are approximated does compression occur. There exist fast DCT algorithms in analogy to the Fast Fourier Transform.

- entity-relationship model — (database, specification) An approach to data modelling proposed by P. Chen in 1976. The model says that you divide your database in two logical parts, entities (e.g. "customer", "product") and relations ("buys", "pays for"). One of the first activities in specifying an application is defining the entities involved and their relationships, e.g. using an entity-relationship diagram to represent a model.

- extended backus-naur form — (language) Any variation on the basic Backus-Naur Form (BNF) meta-syntax notation with (some of) the following additional constructs: square brackets "[..]" surrounding optional items, suffix "*" for Kleene closure (a sequence of zero or more of an item), suffix "+" for one or more of an item, curly brackets enclosing a list of alternatives, and super/subscripts indicating between n and m occurrences. All these constructs can be expressed in plain BNF using extra productions and have been added for readability and succinctness.

- first generation computer — (architecture) A prototype computer based on vacuum tubes and other esoteric technologies. Chronologically, any computer designed before the mid-1950s. Examples include Howard Aiken's Mark 1 (1944), Maunchly and Eckert's ENIAC (1946), and the IAS computer.
- flash lights impressively — (programming, humour) (FLI) /FLY/ A joke assembly language instruction first documented in the late 1970s in "The Hackers Dictionary". The FLI instruction was frequently referred to by engineers when minicomputers such as the DEC PDP-8, PDP-11 and some early microcomputers such as the IMSAI and Altair had dozens of front panel lights. "When the computer is about to do some long I/O operation, stick in a FLI so the accountants won't think the machine has hung again."
