  • backus-naur form — (language, grammar)   (BNF, originally "Backus Normal Form") A formal metasyntax used to express context-free grammars. Backus Normal Form was renamed Backus-Naur Form at the suggestion of Donald Knuth. BNF is one of the most commonly used metasyntactic notations for specifying the syntax of programming languages, command sets, and the like. It is widely used for language descriptions but seldom documented anywhere (how do you document a metasyntax?), so that it must usually be learned by osmosis (but see RFC 2234). Consider this BNF for a US postal address: ::= ::= | "." ::= [] | ::= [] ::= "," This translates into English as: "A postal-address consists of a name-part, followed by a street-address part, followed by a zip-code part. A personal-part consists of either a first name or an initial followed by a dot. A name-part consists of either: a personal-part followed by a last name followed by an optional "jr-part" (Jr., Sr., or dynastic number) and end-of-line, or a personal part followed by a name part (this rule illustrates the use of recursion in BNFs, covering the case of people who use multiple first and middle names and/or initials). A street address consists of an optional apartment specifier, followed by a street number, followed by a street name. A zip-part consists of a town-name, followed by a comma, followed by a state code, followed by a ZIP-code followed by an end-of-line." Note that many things (such as the format of a personal-part, apartment specifier, or ZIP-code) are left unspecified. These lexical details are presumed to be obvious from context or specified somewhere nearby. There are many variants and extensions of BNF, possibly containing some or all of the regexp wild cards such as "*" or "+". EBNF is a common one. In fact the example above isn't the pure form invented for the ALGOL 60 report. "[]" was introduced a few years later in IBM's PL/I definition but is now universally recognised. ABNF is another extension.
  • bargaining scope — the range of topics within the scope of a particular set of negotiations leading to a collective agreement

  • basque provinces — an autonomous region of N Spain, comprising the provinces of Álava, Guipúzcoa, and Vizcaya: inhabited mainly by Basques, who retained virtual autonomy from the 9th to the 19th century. Pop: 1 840 700 (2003 est). Area: about 7250 sq km (2800 sq miles)

  • bear one's cross — a structure consisting essentially of an upright and a transverse piece, used to execute persons in ancient times.
  • beta abstraction — [lambda-calculus] The conversion of an expression to an application of a lambda abstraction to an argument expression. Some subterm of the original expression becomes the argument of the abstraction and the rest becomes its body. E.g. 4+1 --> (\ x . x+1) 4 The opposite of beta abstraction is beta reduction. These are the two kinds of beta conversion.
  • bicapitalisation — The act said to have been performed on trademarks (such as PostScript, NeXT, NeWS, VisiCalc, FrameMaker, TK!solver, EasyWriter) that have been raised above the ruck of common coinage by nonstandard capitalisation. Too many marketroid types think this sort of thing is really cute, even the 2,317th time they do it. Compare studlycaps.

  • cache on a stick — (architecture)   (COAST) Intel Corporation attempt to's standardise the modular L2 cache subsystem in Pentium-based computers. A COAST module should be about 4.35" wide by 1.14" high. According to earlier specifications from Motorola, a module between 4.33" and 4.36" wide, and between 1.12" and 1.16" high is within the COAST standard. Some module vendors, including some major motherboard suppliers, greatly violate the height specification. Another COAST specification violated by many suppliers concerns clock distribution in synchronous modules. The specification requires that the clock tree to each synchronous chip be balanced, i.e. equal length from edge of the connector to individual chips. An unbalanced clock tree increases reflections and noise. For a 256 kilobyte cache module the standard requires the same clock be used for both chips but some vendors use separate clocks to reduce loading on the clock driver and hence increase the clock speed. However, this creates unbalanced loading in other motherboard configurations, such as motherboards with soldered caches in the system.
