  • local mail transfer protocol — (messaging, protocol)   (LMTP) A protocol designed as an alternative to ESMTP for cases where the mail receiver does not manage a queue. LMTP is an application level protocol that runs on top of TCP/IP. It was initially defined in RFC 2033, and uses (with a few changes) the syntax and semantics of ESMTP. It should be used only by specific prior arrangement and configuration, and it must not be used on TCP port 25 (the SMTP port).
  • magnetic particle inspection — a method of testing for cracks and other defects in a magnetic material, such as steel, by covering it with a magnetic powder and magnetizing it: any variation in the concentration of the powder indicates a flaw in the material
  • meter-kilogram-second-ampere — of or relating to the system of units in which the meter, kilogram, second, and ampere are the principal units of length, mass, time, and electric current. Abbreviation: mksa, MKSA.
  • 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
  • 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.
  • online public access catalog — (library)   (OPAC) A computerised system to catalogue and organise materials in a library (the kind that contains books). OPACs have replaced card-based catalogues in many libraries. An OPAC is available to library users (public access).
  • osborne computer corporation — (company)   The unsucessful computer manufacturer founded by Adam Osborne that produced one of the first laptop computers, the Osborne 1.

  • personal liability insurance — Personal liability insurance protects the insured if they are sued for claims that are covered by the insurance policy.
  • playboy of the western world — a satiric comedy (1907) by John Millington Synge.
  • positron emission tomography — the process of producing a PET scan.
  • potassium antimonyl tartrate — a white, water-soluble, sweet and metallic-tasting, poisonous powder or granules, C 4 H 4 KO 7 Sb, used as a mordant for dyeing textiles and leather, and in medicine as an expectorant, for inducing vomiting, and for infections by schistosomes.
  • 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.

  • put one's cards on the table — a usually rectangular piece of stiff paper, thin pasteboard, or plastic for various uses, as to write information on or printed as a means of identifying the holder: a 3″ × 5″ file card; a membership card.
  • put one's hand to the plough — to begin or undertake a task
  • 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.
