- raise specification language — (language) (RSL) (RAISE = Rigorous Approach to Industrial Software Engineering). A wide-spectrum specification and design language developed by ESPRIT Project 315 at CRI A/S, Denmark. Systems may be modular, concurrent and nondeterministic. Specifications may be applicative or imperative, explicit or implicit, abstract or concrete.
- 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.
- reflexive transitive closure — Two elements, x and y, are related by the reflexive transitive closure, R+, of a relation, R, if they are related by the transitive closure, R*, or they are the same element.

- 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)

- simulation oriented language — (language) (SOL) An ALGOL extension for discrete simulation by Donald Knuth and McNeley.
- 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
- special theory of relativity — the state or fact of being relative.
- 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
- strictly decreasing function — a function having the property that for any two points in the domain such that one is larger than the other, the image of the larger point is less than the image of the smaller point.
- strictly increasing function — a function having the property that for any two points in the domain such that one is larger than the other, the image of the larger point is greater than the image of the smaller point.
- 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.
- tannu tuva people's republic — former name of Tuva Autonomous Republic.

- the last word/the final word — If someone has the last word or the final word in a discussion, argument, or disagreement, they are the one who wins it or who makes the final decision.
- the line of least resistance — If you take the line of least resistance in a situation, you do what is easiest, even though you think that it may not be the right thing to do. In American English, you usually talk about the path of least resistance.
- the long and the short of it — the essential points or facts
- 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.

- 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".
- united states postal service — an independent federal agency created in 1971 to replace the Post Office Department as the division of the federal government responsible for postal services. Abbreviation: USPS.
- variable-density wind tunnel — a closed-circuit wind tunnel entirely contained in a casing in which the pressure and therefore the density of the working fluid can be maintained at a preselected value
