  • digital videocassette — a videocassette containing magnetic tape used for high-fidelity digital recording or playback of video. Abbreviation: DVC.
  • direct inward dialing — (communications)   (DID) A service offered by telephone companies which allows the last 3 or 4 digits of a phone number to be transmitted to the destination exchange. For example, a company could have 10 incoming lines, all with the number 234 000. If a caller dials 234 697, the call is sent to 234 000 (the company's exchange), and the digits 697 are transmitted. The company's exchange then routes the call to extension 697. This gives the impression of 1000 direct dial lines, whereas in fact there are only 10. Obviously, only 10 at a time can be used. This system is also used by fax servers. Instead of an exchange at the end of the 234 000 line, a computer running fax server software and fax modem cards uses the last three digits to identify the recipient of the fax. This allows 1000 people to have their own individual fax numbers, even though there is only one 'fax machine'.
  • disassortative mating — the reproductive pairing of individuals that have traits more dissimilar than would likely be the case if mating were random (contrasted with assortative mating).

  • dynamic data exchange — (language)   (DDE, originally Dynamic Data Linking, DDL) A Microsoft Windows 3 hotlink protocol that allows application programs to communicate using a client-server model.

  • emitter coupled logic — (ECL) (Or "Current Mode Logic") A technology for building logic gates where the emitter of a transistor is used as the output rather than its collector. ECL has a propagation time of 0.5 - 2 ns (faster than TTL) and a power dissipation 3 - 10 times higher than TTL.

  • framing specification — A specification of the "protocol bits" that surround the "data bits" on a communications channel to allow the data to be "framed" into chunks, like start and stop bits in EIA-232. It allows a receiver to synchronize at points along the data stream.

  • generic type variable — (programming)   (Also known as a "schematic type variable"). Different occurrences of a generic type variable in a type expression may be instantiated to different types. Thus, in the expression let id x = x in (id True, id 1) id's type is (for all a: a -> a). The universal quantifier "for all a:" means that a is a generic type variable. For the two uses of id, a is instantiated to Bool and Int. Compare this with let id x = x in let f g = (g True, g 1) in f id This looks similar but f has no legal Hindley-Milner type. If we say f :: (a -> b) -> (b, b) this would permit g's type to be any instance of (a -> b) rather than requiring it to be at least as general as (a -> b). Furthermore, it constrains both instances of g to have the same result type whereas they do not. The type variables a and b in the above are implicitly quantified at the top level: f :: for all a: for all b: (a -> b) -> (b, b) so instantiating them (removing the quantifiers) can only be done once, at the top level. To correctly describe the type of f requires that they be locally quantified: f :: ((for all a: a) -> (for all b: b)) -> (c, d) which means that each time g is applied, a and b may be instantiated differently. f's actual argument must have a type at least as general as ((for all a: a) -> (for all b: b)), and may not be some less general instance of this type. Type variables c and d are still implicitly quantified at the top level and, now that g's result type is a generic type variable, any types chosen for c and d are guaranteed to be instances of it. This type for f does not express the fact that b only needs to be at least as general as the types c and d. For example, if c and d were both Bool then any function of type (for all a: a -> Bool) would be a suitable argument to f but it would not match the above type for f.
  • genetic amplification — an increase in the frequency of replication of a DNA segment.
