  • amdahl corporation — (company)   A US computer manufacturer. Amdahl is a major supplier of large mainframes, UNIX and Open Systems software and servers, data storage subsystems, data communications products, applications development software, and a variety of educational and consulting services. Amdahl products are sold in more than 30 countries for use in both open systems and IBM plug-compatible mainframe computing environments. Quarterly sales $397M, profits $13M (Aug 1994). In 1997 Amdahl became a division of Fujitsu.

  • antivivisectionist — a person who is opposed to vivisection
  • aorangi-mount cook — the official name for Mount Cook
  • apostolic delegate — a representative of the pope sent to countries that do not have full or regular diplomatic relations with the Holy See
  • application server — 1. A designer's or developer's suite of software that helps programmers isolate the business logic in their programs from the platform-related code. Application servers can handle all of the application logic and connectivity found in client-server applications. Many application servers also offer features such as transaction management, clustering and failover, and load balancing; nearly all offer ODBC support. 2. Production programs run on a mid-sized computer that handle all application operations between browser-based computers and an organisation's back-end business applications or databases. The application server works as a translator, allowing, for example, a customer with a browser to search an online retailer's database for pricing information. 3. The device on which application server software runs. Application Service Providers offer commercial access to such devices.
  • applied psychology — psychology that is put to practical use
  • arachibutyrophobia — Fear of peanut butter sticking to the roof of one's mouth.
  • arbitration clause — a clause in a contract laying down that disputes between the parties should be settled by arbitration
  • arctic archipelago — group of mostly large islands in the Arctic Ocean off the N coast of Canada
  • aristotelian logic — the logical theories of Aristotle as developed in the Middle Ages, concerned mainly with syllogistic reasoning: traditional as opposed to modern or symbolic logic
  • arkansas toothpick — a bowie knife or similar sharp knifelike implement.
  • army of occupation — an army that goes into a defeated country to enforce peace terms, keep order, etc.
  • artificial horizon — an aircraft instrument, using a gyroscope, that indicates the aircraft's attitude in relation to the horizontal
  • asciibetical order — (jargon, programming)   /as'kee-be'-t*-kl or'dr/ Used to indicate that data is sorted in ASCII collated order rather than alphabetical order. The main difference is that, in ASCII, all the upper case letters come before any of the lower case letters so, e.g., "Z" comes before "a".
  • associate director — a person who is joined with one or more other directors in an enterprise, business, etc, having equal or nearly equal status
  • associated company — a company which is largely controlled by its parent company because the latter owns anything up to 50% of the shares
  • association cortex — any of the regions of the cerebral cortex of the brain connected by numerous nerve fibers to all parts of both cerebral hemispheres and coordinating such higher activities as learning and reasoning.
  • associative cortex — the part of the cortex that does not have direct connections to the senses or motor system and is thought to be involved in higher mental processes
  • associative memory — content addressable memory
  • astrological chart — map of constellations at certain time
  • astrometric binary — a binary star that can be recognized as such because of its undulating proper motion.
  • astronomical clock — a complex clock showing astronomical phenomena, such as the phases of the moon
  • asymptotic freedom — a property of the force between quarks, according to quantum chromodynamics, such that they behave almost like free particles when they are close together within a hadron.
  • asynchronous logic — (architecture)   A data-driven circuit design technique where, instead of the components sharing a common clock and exchanging data on clock edges, data is passed on as soon as it is available. This removes the need to distribute a common clock signal throughout the circuit with acceptable clock skew. It also helps to reduce power dissipation in CMOS circuits because gates only switch when they are doing useful work rather than on every clock edge. There are many kinds of asynchronous logic. Data signals may use either "dual rail encoding" or "data bundling". Each dual rail encoded Boolean is implemented as two wires. This allows the value and the timing information to be communicated for each data bit. Bundled data has one wire for each data bit and another for timing. Level sensitive circuits typically represent a logic one by a high voltage and a logic zero by a low voltage whereas transition signalling uses a change in the signal level to convey information. A speed independent design is tolerant to variations in gate speeds but not to propagation delays in wires; a delay insensitive circuit is tolerant to variations in wire delays as well. The purest form of circuit is delay-insensitive and uses dual-rail encoding with transition signalling. A transition on one wire indicates the arrival of a zero, a transition on the other the arrival of a one. The levels on the wires are of no significance. Such an approach enables the design of fully delay-insensitive circuits and automatic layout as the delays introduced by the layout compiler can't affect the functionality (only the performance). Level sensitive designs can use simpler, stateless logic gates but require a "return to zero" phase in each transition.
  • at the instance of — at the suggestion or instigation of
