- 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. - appraisal drilling — (in the oil industry) drilling carried out once oil or gas has been discovered in order to assess the extent of the field, the reserves, the possible rate of production, and the properties of the oil or gas

- assignment problem — (mathematics, algorithm) (Or "linear assignment") Any problem involving minimising the sum of C(a, b) over a set P of pairs (a, b) where a is an element of some set A and b is an element of set B, and C is some function, under constraints such as "each element of A must appear exactly once in P" or similarly for B, or both. For example, the a's could be workers and the b's projects. The problem is "linear" because the "cost function" C() depends only on the particular pairing (a, b) and is independent of all other pairings.
- australopithecines — Plural form of australopithecine.
- biological parents — the biological mother and father of a child
- bipolar transistor — (electronics) A transistor made from a sandwich of n- and p-type semiconductor material: either npn or pnp. The middle section is known as the "base" and the other two as the "collector" and "emitter". When used as an amplifying element, the base to emitter junction is in a "forward-biased" (conducting) condition, and the base to collector junction is "reverse-biased" or non-conducting. Small changes in the base to emitter current (the input signal) cause either holes (for pnp devices) or free electrons (for npn) to enter the base from the emitter. The attracting voltage of the collector causes the majority of these charges to cross into and be collected by the collector, resulting in amplification. Contrast field effect transistor.
- blocking capacitor — a capacitor that blocks the passage of direct current but allows alternating current to pass

- daisywheel printer — (printer) A kind of impact printer where the characters are arranged on the ends of the spokes of a wheel (resembling the petals on a daisy). The wheel (usually made of plastic) is rotated to select the character to print and then an electrically operated hammer mechanism bends the selected spoke forward slightly, sandwiching an ink ribbon between the character and the paper, as in a typewriter. One advantage of this arrangement over that of a typewriter is that different wheels may be inserted to produce different typefaces.
