- 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.
- standard normal distribution — a normal distribution with mean zero and variance 1, with probability density function [exp(–1⁄2x2)]/√2π
- 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.
- systems administrators guild — (body, job) (SAGE) A special technical group of the USENIX Association.
- television interface adaptor — (hardware, graphics) (TIA) The graphics chip in the Atari 2600, also used as a sound chip for some arcade game.
- text reckoning and compiling — (language) (TRAC) An interactive macro generator language for string manipulation by Calvin N. Mooers and Peter Deutsch of Sun Microsystems. TAC derived ideas from Macro SAP. There are versions for PDP-1, PDP-8, PDP-10 and PDP-11. See also MINT, SAM76. E-mail: Preston Briggs <[email protected]>.
- the everglades national park — the Florida park established to preserve the flora and fauna of the Everglade swamps
- 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 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.
- through rose-colored glasses — with optimism, esp. undue optimism
- to leave a lot to be desired — If you say that something leaves a lot to be desired, you mean that it is not as good as it should be.
- 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
- virgin islands national park — a national park on St. John Island, Virgin Islands: prehistoric Indian relics. 24 sq. mi. (62 sq. km).
- walden, or life in the woods — a book of philosophical observations (1854) by Thoreau.
- will never do/would never do — If you say that something will never do or would never do, you are saying, often humorously, that you think it is not appropriate or not suitable in some way.
- 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).
