- national semiconductor 32000 — (processor) (NS32000)
The first of a series of microprocessors from National Semiconductor. The 320xx processors have an interface which allows coprocessors such as FPUs and MMUs to be attached in a chain. The 320xx was the predecessor of the Swordfish processor. - object-oriented polymorphism — (programming) The kind of polymorphism found in object-oriented programming languages where a variable can refer to an object whose class is not known exactly until run time. A method can use a variable of a given class - call other methods on it, pass it as an argument, etc. - without needing to know to which subclass it refers, as long as its actual class is compatible with those uses.
- ousterhout's false dichotomy — Ousterhout's dichotomy
- palestinian autonomous areas — the Gaza Strip and the West Bank in Israel: these areas were granted autonomous status under the control of the Palestinian National Authority following the 1993 peace agreement between Israel and the Palestine Liberation Organization

- quick mail transfer protocol — (communications) (QMTP) An SMTP replacement that works better over high latency links as it doesn't require as much interaction as SMTP. QMTP listens on port 209 and is used by qmail.
- real time streaming protocol — (multimedia, networking, protocol) (RTSP) An application layer protocol for controlling delivery of a stream of real-time multimedia content. RTSP allows users to start playing from a certain position. It does not actually deliver the data, but works alongside existing delivery channels such as UDP, TCP, or IP multicast. RTSP was developed by RealNetworks, Netscape Communications, and Columbia University, and is described in RFC 2326, April 1998. RTSP is an IETF proposed standard.
- real-estate investment trust — an unincorporated trust created for the purpose of investing in real property or to extend credit to those engaged in construction. Abbreviation: REIT.
- real-time transport protocol — (protocol) (RTP) An Internet protocol for transmitting real-time data such as audio and video. RTP itself does not guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support streaming data. Typically, RTP runs on top of the UDP protocol, although the specification is general enough to support other transport protocols. RTP has received wide industry support. Netscape intends to base its LiveMedia technology on RTP, and Microsoft claims that its NetMeeting product supports RTP.
- scanning electron microscope — a device in which the specimen is examined point by point directly in a moving electron beam, and electrons reflected by the specimen are used to form a magnified, three-dimensional image on a television screen. Abbreviation: SEM.
- second axiom of countability — the property satisfied by a topological space in which the neighborhood system of each point has a base consisting of a countable number of neighborhoods (first axiom of countability) or the property satisfied by a topological space that has a base for its topology consisting of a countable number of subsets of the space (second axiom of countability)
- second 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)
- second-order lambda-calculus — (language) (SOL) A typed lambda-calculus.
- sell someone a bill of goods — to persuade someone by deception or misrepresentation to accept, believe, or do something

- simulation oriented language — (language) (SOL) An ALGOL extension for discrete simulation by Donald Knuth and McNeley.
- single in-line memory module — (storage) (SIMM) A small circuit board or substrate, typically about 10cm x 2cm, with RAM integrated circuits or die on one or both sides and a single row of pins along one long edge. Several SIMMs are mounted with their substrates at right-angles to the main circuit board (the motherboard). This configuration allows greater packing density than direct mounting of, e.g. DIL (dual in-line) RAM packages on the motherboard. In 1993 one SIMM typically held one or four megabytes, by early 1997 one could hold 8, 16, or 32 MB.
- single sideband transmission — a method of transmitting radio waves in which either the upper or the lower sideband is transmitted, the carrier being either wholly or partially suppressed. This reduces the required bandwidth and improves the signal-to-noise ratio
- smooth endoplasmic reticulum — a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials.
- special power of appointment — authority to appoint persons from a particular class to take an estate or interest in property
- spectral luminous efficiency — a measure of the efficiency of radiation of a given wavelength in producing a visual sensation. It is equal to the ratio of the radiant flux at a standard wavelength to that at the given wavelength when the standard wavelength is chosen so that the maximum value of this ratio is unity
- supplemental security income — income provided by the U.S. government to needy aged, blind, and disabled persons. Abbreviation: SSI.
- systemic lupus erythematosus — an autoimmune inflammatory disease of the connective tissues, occurring mainly among middle-aged women, chiefly characterized by skin eruptions, joint pain, recurrent pleurisy, and kidney disease. Abbreviation: SLE.
- systems administrators guild — (body, job) (SAGE) A special technical group of the USENIX Association.
- the medical research council — a government body that uses public funds to finance research in medicine
- the world owes them a living — If you say that someone thinks that the world owes them a living, you are criticizing them because they think it is their right to have a comfortable life without having to make any effort at all.
- tissue plasminogen activator — an anticlotting enzyme, naturally occurring in small amounts in the blood.
- to be no let-up in something — if there is no let-up in something, usually something unpleasant, there is no reduction in the intensity of it

- to make a clean breast of it — If you make a clean breast of something, you tell someone the truth about yourself or about something wrong that you have done.
- to make someone's blood boil — If you say that something makes your blood boil, you are emphasizing that it makes you very angry.
- to play into someone's hands — If you play into someone's hands, you do something which they want you to do and which places you in their power.
- to ruffle someone's feathers — To ruffle someone's feathers means to cause them to become very angry, nervous, or upset.
- to take something lying down — If someone takes an insult or attack lying down, they accept it without protesting.
- tree transformation language — (functional programming) (TXL) A hybrid functional language and rule-based language developed by J.R. Cordy <[email protected]> et al of Queen's University, Canada in 1988. TXL is suitable for performing source to source analysis and transformation and for rapid prototyping of new languages and language processors. It uses structural transformation based on term rewriting. TXL has been particularly successful in software engineering tasks such as design recovery, refactoring, and reengineering. Most recently it has been applied to artificial intelligence tasks such as recognition of hand-written mathematics, and to transformation of structured documents in XML. TXL takes as input an arbitrary context-free grammar in extended BNF-like notation, and a set of show-by-example transformation rules to be applied to inputs parsed using the grammar. TXL supports the notion of agile parsing, the ability to tailor the grammar to each particular task using "grammar overrides".
- very small aperture terminal — (communications) (VSAT) A kind of ground station used to contact a communications satellite such as INMARSAT.
- wake up and smell the coffee — to face up to reality, especially in an unpleasant situation
- xerox data systems model 530 — (computer) (XDS 530) A computer from the Scientific Data Systems range, announced sometime after 1968 when Xerox bought out SDS. The XDS 530 was probably under development at SDS before the buy-out but only announced afterwards.
- xerox data systems model 940 — (computer) (SDS 940, XDS 940) A time-sharing system, announced in February 1966, developed by Scientific Data Systems with help from The University of California at Berkeley and Tymshare. SDS 940 was backward compatible with SDS's previous systems (except the 12-bit SDS 92). It had monitor and user modes, dynamic program relocation, automatic memory fragmentation, and system protection. After 1968 Xerox bought out SDS and renamed the SDS machines "Xerox Data Systems" (XDS). Xerox then produced the XDS 530.
- zeroth law of thermodynamics — the principle that any two systems in thermal equilibrium with a third system are in thermal equilibrium with each other. Compare law of thermodynamics (def 2).
