- personalized array translator — (language) (PAT) A small subset of APL. E-mail: <[email protected]>.
- put the cart before the horse — a heavy two-wheeled vehicle, commonly without springs, drawn by mules, oxen, or the like, used for the conveyance of heavy goods.
- quantum-dot cellular automata — (electronics, computing) (QCA) Quantum logic circuits created by orientating pairs of quantum cells so that their relative positions determine their affect on each other. This is functionally analogous but structurally different from how individual gates in integrated circuits are combined to create logical and memory circuitry. The advantages of quantum-dot cellular automata over conventional circuitry are extremely small size/high density, low power requirements, and potentially high processing speeds. Disadvantages (in 2000) are difficulty of fabrication and low yield. See also: quantum cell wire.
- recommended dietary allowance — the amount of an essential nutrient, as a vitamin or mineral, that has been established by the Food and Nutrition Board of the National Academy of Sciences as adequate to meet the average daily nutritional needs of most healthy persons according to age group and sex. Abbreviation: RDA.
- roll out the red carpet (for) — to welcome and entertain in a grand and impressive style
- single edge contact cartridge — (hardware) (SEC, SECC) The cased daughterboard housing Intel's Pentium II, Pentium III, and Xeon microprocessors. A SECC fits into a Slot 1 or Slot 2 connector.
- software description database — (networking) Archie's database of names and short descriptions of many of the software packages, documents (like RFCs and educational material), and data files that are available via the Internet.
- suppressed carrier modulation — an amplitude-modulated wave in which only the sidebands are transmitted, the carrier being removed
- surgical specialist registrar — a hospital doctor senior to a house officer but junior to a consultant, specializing in surgery
- synchronous digital hierarchy — (communications, standard) (SDH) An international digital telecommunications network hierarchy which standardises transmission around the bit rate of 51.84 megabits per second, which is also called STS-1. Multiples of this bit rate comprise higher bit rate streams. Thus STS-3 is 3 times STS-1, STS-12 is 12 times STS-1, and so on. STS-3 is the lowest bit rate expected to carry ATM traffic, and is also referred to as STM-1 (Synchronous Transport Module-Level 1). The SDH specifies how payload data is framed and transported synchronously across optical fibre transmission links without requiring all the links and nodes to have the same synchronized clock for data transmission and recovery (i.e. both the clock frequency and phase are allowed to have variations, or be plesiochronous). SDH offers several advantages over the current multiplexing technology, which is known as Plesiochronous Digital Hierarchy. Where PDH lacks built-in facilities for automatic management and routing, and locks users into proprietary methods, SDH can improve network reliability and performance, offers much greater flexibility and lower operating and maintenance costs, and provides for a faster provision of new services. Under SDH, incoming traffic is synchronized and enhanced with network management bits before being multiplexed into the STM-1 fixed rate frame. The fundamental clock frequency around which the SDH or SONET framing is done is 8 KHz or 125 microseconds. SONET (Synchronous Optical Network) is the American version of SDH.
- the royal shakespeare company — a British theatre company based mainly in Stratford-upon-Avon
- the royal ulster constabulary — (formerly) the police force in Northern Ireland from 1922 to 2001, superseded by the Police Service of Northern Ireland

- war of the spanish succession — a war (1701–14) fought by Austria, England, the Netherlands, and Prussia against France and Spain, arising from disputes about the succession in Spain after the death of Charles II of Spain.
- wide area information servers — (networking, information science) (WAIS) A distributed information retrieval system. WAIS is supported by Apple Computer, Thinking Machines and Dow Jones. Clients are able to retrieve documents using keywords. The search returns a list of documents, ranked according to the frequency of occurrence of the keyword(s) used in the search. The client can retrieve text or multimedia documents stored on the server. WAIS offers simple natural language input, indexed searching for fast retrieval, and a "relevance feedback" mechanism which allows the results of initial searches to influence future searches. It uses the ANSI Z39.50 service. Public domain implementations are available. Other information retrieval systems include archie, Gopher, Prospero, and web.
- windows hardware quality labs — (body, standard) (WHQL) A Microsoft body that produces and supports the Microsoft Hardware Compatibility Test kit for current Microsoft operating systems. Products are tested with the kit to ensure that they meet Microsoft standards for compatibility with Windows and to qualify to use the "Designed for Microsoft Windows" logos.
- within earshot/out of earshot — If you are within earshot of someone or something, you are close enough to be able to hear them. If you are out of earshot, you are too far away to hear them.
- you can't hear yourself think — If you say that you can't hear yourself think, you are complaining and emphasizing that there is a lot of noise, and that it is disturbing you or preventing you from doing something.
