- transistor-transistor logic — (TTL) A common semiconductor technology for building discrete digital logic integrated circuits. It originated from Texas Instruments in 1965. There have been several series of TTL logic: 7400: 10 ns propagation time, 10 mW/gate power consumption, obsolete; 74L00: Low power: higher resistances, less dissipation (1 mW), longer propagation time (30 ns); 74H00: High power: lower resistances, more dissipation: less sensitivity for noise; 74S00: Schottky-clamped: faster switching (3 ns, 19 mW) by using Schottky diodes to prevent the transistors from saturation; 74LS00: Low power, Schottky-clamped (10 ns, 2 mW); 74AS00: Advanced Schottky: faster switching, less dissipation, (1.5 ns, 10 mW); 74ALS00: Advanced Low power Schottky (4 ns, 1.3 mW). For each 74xxx family there is a corresponding 54xxx family. The 74 series are specified for operation at 0 - 70 C whereas the 54 (military) series can operate at -55 - 125 C See also CMOS, ECL.
- united nations organization — the United Nations. Abbreviation: UNO, U.N.O.
- united service organization — a private, non-profit organization that provides morale and recreational services to members of the US military, with programmes in 140 centres worldwide
- universal naming convention — (networking) (UNC) The type of file system path used in Microsoft Windows networking to completely specify a directory on a file server. The basic format is: \\servername\sharename where "servername" is the hostname or IP address of a network file server, and "sharename" is the name of a shared directory on the server. This is related to the conventional MS-DOS "C:\windows" style of directory name. E.g. \\server1\dave might be set up to point to C:\users\homedirs\dave on a server called "server1". It is possible to execute a program using this convention without having to specifically link a drive, by running: \\server\share\directory\program.exe The undocumented DOS command, TRUENAME can be used to find out the UNC name of a file or directory on a network drive. Even Microsoft don't know whether UNC stands for "Universal Naming Convention" or "Uniform Naming Convention", both appear on their website, sometimes withing the same document, but with a preference for "Universal".
- university grants committee — an advisory committee of the British government, which advised on the distribution of grant funding amongst British universities. It was in existence from 1919 until 1989. Its functions have now largely been taken over by the higher education funding councils (HEFCE (England), SHEFC (Scotland), HEFCW (Wales), and the Department for Employment and Learning in Northern Ireland)
- western digital corporation — (company) A company founded in 1970 as a specialised semiconductor manufacturer, which today manufactures and sells microcomputer products including small form factor hard disk drives for personal computers, integrated circuits and circuit boards for graphics, storage, communications, battery management, and logic functions.
- wirehaired pointing griffon — griffon2 (def 2).
- working families tax credit — (in Britain) a means-tested allowance paid to single parents or families who have at least one dependent child, who work at least 16 hours per week, and whose earnings are low. It replaced family credit
