  • multimedia personal computer — (multimedia)   (MPC) A specification published by the Multimedia PC Marketing Council in 1990 to encourage the adoption of a standard multimedia computing platform. In May 1993, the MPC Marketing Council published a new specification called MPC Level 2 Specification as an enhanced multimedia computer standard. The original MPC specification, now also known as the MPC Level 1 Specification, continues in full effect. The appearance of the MPC or MPC2 certification mark on a computer system or upgrade kit indicates that the hardware meets the corresponding (Level 1 or Level 2) MPC Marketing Council specification. Software bearing the Multimedia PC mark has been designed to work on Multimedia PC licensed hardware. By establishing a standard platform, certifying hardware compliance and providing inter-operability between software and hardware for the consumer, the MPC Marketing Council is encouraging widespread use of multimedia applications and hardware.
  • national physical laboratory — a UK establishment founded in 1900 at Teddington to carry out research in physics and monitor standards of measurement
  • numerical weather prediction — a method of predicting weather through the use of high-speed computers, specifically by the time integration of the fundamental equations of hydrodynamics in a mathematically modeled atmosphere.
  • object persistence framework — (programming)   (OPF) Any system for storing objects so they can be reloaded into a future session. Typically this will use a relational database along with some kind of object relational mapping. Another typical solution would store objects in XML files (a form of serialisation). One of the trickier problems to solve is how to maintain references between objects, e.g. replacing memory pointers with unique names or identifiers. Virtually identical considerations apply to transferring objects, or indeed any kind of data structure, from one process to another via some communications channel, e.g. a TCP/IP connection.
  • osborne computer corporation — (company)   The unsucessful computer manufacturer founded by Adam Osborne that produced one of the first laptop computers, the Osborne 1.
  • paradox application language — (PAL) The programming language for Paradox, Borland's relational database.
  • partial equivalence relation — (PER) A relation R on a set S where R is symmetric (x R y => y R x) and transitive (x R y R z => x R z) and where there may exist elements in S for which the relation is not defined. A PER is an equivalence relation on the subset for which it is defined, i.e. it is also reflexive (x R x).
  • peaches-and-cream complexion — a pale complexion with rosy cheeks
  • permanent virtual connection — Permanent Virtual Circuit
  • persistent organic pollutant — a toxin resulting from a manufacturing process, which remains in the environment for many years
  • personal liability insurance — Personal liability insurance protects the insured if they are sued for claims that are covered by the insurance policy.
  • plug compatible manufacturer — (company)   (PCM) A manufacturer of equipment that some other manufacturer's system can identify and work with. The PCM's device replaces the original manufacturer's. Most PCMs competed with IBM. PCM devices normally offer a cost-performance benefit over the original device. For example, several PCM versions of the Direct-Access Storage Device IBM 3350 offered twice the storage and improved data access (dual port). Plug compatible devices include replacement CPUs, such as the Hitachi 7/90 series (which could be substituted for IBM 3090 series processors), I/O subsystems, and dumb terminals like the IBM 3270.
  • presidencia roque saenz pena — a city in N Argentina.
  • principle of complementarity — complementarity principle.
  • probability density function — a function of a continuous variable whose integral over a region gives the probability that a random variable falls within the region.
  • program composition notation — (PCN) A specification language for parallelism between C and Fortran modules. PCN provides a simple language for specifying concurrent algorithms, interfaces to Fortran and C, a portable toolkit that allows applications to be developed on a workstation or small parallel computer and run unchanged on supercomputers and integrated debugging and performance analysis tools. PCN was developed at Argonne National Laboratory and the California Institute of Technology. It has been used to develop a wide variety of applications, in areas such as climate modelling, fluid dynamics, computational biology, chemistry, and circuit simulation. Version 2.0 runs on networks of workstations: Sun-4, NeXT, RS/6000, SGI; multicomputers: iPSC/860, Touchstone DELTA; and shared memory multiprocessors: Symmetry/Dynix.

  • quaternary ammonium compound — any of a class of salts derived from ammonium in which the nitrogen atom is attached to four organic groups, as in benzalkonium chloride; the salts are cationic surface-active compounds used as antiseptics and disinfectants.
  • quick mail queueing protocol — (communications)   (QMQP) A protocol that provides a central e-mail queue for a cluster of hosts. QMOP is supposed to provide fast transfers of messages with many recipients as it can batch them up as a single transaction. It listens on port 628.
  • quick mail transfer protocol — (communications)   (QMTP) An SMTP replacement that works better over high latency links as it doesn't require as much interaction as SMTP. QMTP listens on port 209 and is used by qmail.
  • raise specification language — (language)   (RSL) (RAISE = Rigorous Approach to Industrial Software Engineering). A wide-spectrum specification and design language developed by ESPRIT Project 315 at CRI A/S, Denmark. Systems may be modular, concurrent and nondeterministic. Specifications may be applicative or imperative, explicit or implicit, abstract or concrete.
  • real time streaming protocol — (multimedia, networking, protocol)   (RTSP) An application layer protocol for controlling delivery of a stream of real-time multimedia content. RTSP allows users to start playing from a certain position. It does not actually deliver the data, but works alongside existing delivery channels such as UDP, TCP, or IP multicast. RTSP was developed by RealNetworks, Netscape Communications, and Columbia University, and is described in RFC 2326, April 1998. RTSP is an IETF proposed standard.
  • real-time transport protocol — (protocol)   (RTP) An Internet protocol for transmitting real-time data such as audio and video. RTP itself does not guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support streaming data. Typically, RTP runs on top of the UDP protocol, although the specification is general enough to support other transport protocols. RTP has received wide industry support. Netscape intends to base its LiveMedia technology on RTP, and Microsoft claims that its NetMeeting product supports RTP.
  • regular expression converter — CONVERT
  • rocky mountain national park — a national park in N Colorado. 405 sq. mi. (1050 sq. km).
  • rocky mountain spotted fever — an infectious disease characterized by high fever, pains in joints, bones, and muscles, and a cutaneous eruption, caused by rickettsii and transmitted by ticks: first reported in the Rocky Mountain area, but now more widely distributed.
  • routing information protocol — 1.   (networking)   (RIP) A distance vector, as opposed to link state, routing protocol. RIP is an Internet standard Interior Gateway Protocol defined in STD 34, RFC 1058 and updated by RFC 1388. See also Open Shortest Path First. 2.   (networking)   (RIP) A companion protocol to IPX for exchange of routing information in a Novell network. RIP has been partly superseded by NLSP. It is not related to the Internet protocol of the same name.
