symbol manipulation program — (SMP) Steven Wolfram's earlier symbol manipulation program, before he turned to Mathematica.
synchronous optical network — (networking) (SONET) A broadband networking standard based on point-to-point optical fibre networks. SONET will provide a high-bandwidth "pipe" to support ATM-based services. The SONET standard will establish a digital hierarchical network with a consistent worldwide transport scheme. SONET has been designed to take advantage of fibre, in contrast to the plain old telephone system which was designed for copper wires. SONET carries circuit-switched data in frames at speeds in multiples of 51.84 megabits per second (Mbps) up to 48 * 51.84 Mbps = 2.488 gigabits per second. Since SONET uses multiple channels to transmit data, each SONET frame can be considered to be a two-dimensional table of bytes that is 9 rows high and 90 columns deep. For every OC-n level, SONET can transmit n number of frames at a given time. Groups of frames are called superframes. SONET is the American version of SDH.

the long and (the) short of — the whole story of in a few words; gist or point of
third law of thermodynamics — any of three principles variously stated in equivalent forms, being the principle that the change of energy of a thermodynamic system is equal to the heat transferred minus the work done (first law of thermodynamics) the principle that no cyclic process is possible in which heat is absorbed from a reservoir at a single temperature and converted completely into mechanical work (second law of thermodynamics) and the principle that it is impossible to reduce the temperature of a system to absolute zero in a finite number of operations (third law of thermodynamics)

to take you out of yourself — If something takes you out of yourself, it makes you feel better and so you forget all your worries and unhappiness.
to the best of your ability — as well as you can
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.
universal computer protocol — (communications, protocol) An earlier form of External Machine Interface (EMI).
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".
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.

wireless local area network — a wireless broadband system for linking personal computers and workstations with each other in order to share data, devices, programs, etc.: usually confined to one office, building, or home.
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
