- power supply unit — (hardware) (PSU) An electronic module that converts high voltage (110 or 240 VAC) alternating current mains electricity into smoothed direct current at the various differnt voltages required by the motherboard; internal peripheral devices, cheifly storage devices: hard disks, CD or DVD, floppy disks and external connections such as USB. A PSU needs a high enough power output rating to supply all the devices connected to it and should output as little as possible electrical noise, both on the output wires and as electromagnetic radiation. See also uninterruptable power supply.

- production system — (programming) A production system consists of a collection of productions (rules), a working memory of facts and an algorithm, known as forward chaining, for producing new facts from old. A rule becomes eligible to "fire" when its conditions match some set of elements currently in working memory. A conflict resolution strategy determines which of several eligible rules (the conflict set) fires next. A condition is a list of symbols which represent constants, which must be matched exactly; variables which bind to the thing they match and "<> symbol" which matches a field not equal to symbol. Example production systems are OPS5, CLIPS, flex.

- rapid prototyping — (programming) The creation of a working model of a software module to demonstrate the feasibility and suitability of the function. The prototype is expected to be replaced or refined before inclusion in the final product. Rapid prototyping contrasts with a DIRFT approach which emphasises careful design and implementation to avoid the overheads of debugging and testing prototype code. Rapid prototyping is appropriate when the requirements are unclear or likely to change (which is most of the time).

Software is also available to allow uucp to work over Ethernet though there are better alternatives in this case, e.g. FTP or rcp for file transfer, SMTP for electronic mail or NNTP for news. The term is now also used to describe the large international network which uses UUCP to pass Usenet news and electronic mail, also known as "UUCPNET". See also cu, uuencode.
