- programmable array logic — (hardware) (PAL) A family of fuse-programmable logic integrated circuits originally developed by MMI. Registered or combinatorial output functions are modelled in a sum of products form. Each output is a sum (logical or) of a fixed number of products (logical and) of the input signals. This structure is well suited for automatic generation of programming patterns by logic compilers. PAL devices are programmed by blowing the fuses permanently using overvoltage. Today, more complex devices based on the same original architecture are available (CPLD's for Complex PLD's) that incorporate the equivalent of several original PAL chips. PAL chips are, however, still popular due to their high speed.

- referential transparency — (programming) An expression E is referentially transparent if any subexpression and its value (the result of evaluating it) can be interchanged without changing the value of E. This is not the case if the value of an expression depends on global state which can change value. The most common example of changing global state is assignment to a global variable. For example, if y is a global variable in: f(x) { return x+y; } g(z) { a = f(1); y = y + z; return a + f(1); } function g has the "side-effect" that it alters the value of y. Since f's result depends on y, the two calls to f(1) will return different results even though the argument is the same. Thus f is not referentially transparent. Changing the order of evaluation of the statements in g will change its result. We could make f above referentially transparent by passing in y as an argument: f(x, y) = x+y Similarly, g would need to take y as an argument and return its new value as part of the result: g(z, y) { a = f(1, y); y' = y+z; return (a + f(1, y'), y'); } Referentially transparent programs are more amenable to formal methods and easier to reason about because the meaning of an expression depends only on the meaning of its subexpressions and not on the order of evaluation or side-effects of other expressions. We can stretch the concept of referential transparency to include input and output if we consider the whole program to be a function from its input to its output. The program as a whole is referentially transparent because it will always produce the same output when given the same input. This is stretching the concept because the program's input may include what the user types, the content of certain files or even the time of day. If we do not consider global state like the contents of files as input, then writing to a file and reading what was written behaves just like assignment to a global variable. However, if we must consider the state of the universe as an input rather than global state then any deterministic system would be referentially transparent! See also extensional equality, observational equivalence.
- responsibility allowance — payment made to somebody who has special responsibilities
- selective service system — the U.S. federal agency that facilitates the mobilization of military forces by requiring the registration of males between the ages of 18 and 26 years. Abbreviation: SSS.

- succinylcholine chloride — a crystalline compound, C 1 4 H 3 0 Cl 2 N 2 O 4 , used as a skeletal muscle relaxant in surgical procedures.
- syquest technology, inc. — (company, hardware) An early entrant into the removable hard disk market for personal computers. For may years SyQuest held the market, particularly as a method of transferring large desktop publisher documents to printers. SyQuest aim their products to give personal computer users "endless" hard drive space for data-intensive applications like desktop publishing, Internet information management, pre-press, multimedia, audio, video, digital photography, fast backup, data exchange, archiving, confidential data security and easy portability for the road. At the top of their current (Mar 1997) range are two drives, The SyJet 1.5 GB a 3.5 inch, double platter removable drive and the EZFlyer 230 MB also on 3.5 inch media. A cartridge holding over 4.7GB is promised before the end of 1997. In recent years they have not fared as well in the market, whilst Iomega has cornered the Small Office/Home Office (SOHO) market. Over the period 1995 to 1997 sales declined resulting in a series of losses. In the first quarter of 1997 these losses had been reduced to $6.8 million with net revenues increasing to $48.3 million. This compares to a net loss of $33.8 million, or $2.98 per share, on net revenues of $78.7 million for the same period the year before. It would appear that substantial restructuring has occurred over the past few years.
- telephony user interface — (communications) (TUI) Either a software interface to telephony (e.g. a phone-capable PC) or a DTMF-based interface to software (e.g. voicemail).
- to play your cards right — If you say that someone will achieve success if they play their cards right, you mean that they will achieve success if they act skilfully and use the advantages that they have.

- tricyclic antidepressant — pertaining to or embodying three cycles.
- very large crude carrier — VLCC.
- virtual software factory — (programming, tool) (VSF) A product from Systematica which allows users to develop CASE tools appropriate to any software engineering methodology.
- visual component library — (programming) VCL A application framework library for Microsoft Windows and Borland Software Corp.'s Delphi and C++Builder rapid application development software. VCL was originally designed for Delphi but is now also used for C++Builder. This replaces OWL Object Windows Library as Borland's Windows C++ framework of choice. VCL encapsulates the C-based Win32 API into a much easier to use, object-oriented form. Like its direct rival, Microsoft Foundation Class Library (MFC), VCL includes classes to create Windows programs. The VCL component class can be inherited to create new VCL components, which are the building blocks of Delphi and C++Builder applications. VCL components are somewhat in competition with ActiveX controls, though a VCL wrapper can be created to make an ActiveX control seem like a VCL component.
- voluntary aid detachment — (in World War I) an organization of British women volunteers who assisted in military hospitals and ambulance duties
- water of crystallization — water of hydration, formerly thought necessary to crystallization: now usually regarded as affecting crystallization only as it forms new molecular combinations.
- which way the wind blows — air in natural motion, as that moving horizontally at any velocity along the earth's surface: A gentle wind blew through the valley. High winds were forecast.
- win (or lose) by a neck — to win (or lose) by the length of a horse's head and neck
- wired equivalent privacy — (networking, standard) (WEP) IEEE 802.11:1999. A cryptographic privacy algorithm, based on the RC4 encryption engine, used to provide confidentiality for 802.11 wireless networks. WEP is intended to provide roughly the same level of confidentiality for wireless data as a wired LAN (Ethernet), which is NOT protected by encryption. WEP is often wrongly expanded as "Wireless Encryption Protocol". WEP is a protocol that provides encryption used on wireless networks but that's not what it stands for.
- yellow-bellied sapsucker — a woodpecker, Sphyrapicus varius, of eastern North America, having a red patch on the forehead and black and white plumage with a pale-yellow abdomen, and feeding on sap from trees.
