  • lloyd's register of shipping — an annual publication giving details of all ships that have been built according to the various classifications established by this society
  • 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
  • manpower services commission — (in Britain, formerly) an organization providing training for adult workers
  • 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.
  • morpheme structure condition — (in generative phonology) a constraint on the occurrence of sounds or sequences of sounds in the phonological representation of morphemes.

  • moving picture experts group — (compression, standard, algorithm, file format, body)   (MPEG, ISO/IEC JTC1/SC29 WG11) An ISO committee that generates standards for digital video compression and audio. Also the name of their algorithms.
  • 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.

  • 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.
  • object-oriented polymorphism — (programming)   The kind of polymorphism found in object-oriented programming languages where a variable can refer to an object whose class is not known exactly until run time. A method can use a variable of a given class - call other methods on it, pass it as an argument, etc. - without needing to know to which subclass it refers, as long as its actual class is compatible with those uses.
  • on (or upon) someone's head — as someone's burden, responsibility, or misfortune
  • 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).
  • open systems interconnection — (networking)   (OSI-RM, OSI Reference Model, seven layer model) A model of network architecture and a suite of protocols (a protocol stack) to implement it, developed by ISO in 1978 as a framework for international standards in heterogeneous computer network architecture. The OSI architecture is split between seven layers, from lowest to highest: 1 physical layer, 2 data link layer, 3 network layer, 4 transport layer, 5 session layer, 6 presentation layer, 7 application layer. Each layer uses the layer immediately below it and provides a service to the layer above. In some implementations a layer may itself be composed of sub-layers. OSI is the umbrella name for a series of non-proprietary protocols and specifications, comprising, among others, the OSI Reference Model, ASN.1 (Abstract Syntax Notation 1), BER (Basic Encoding Rules), CMIP and CMIS (Common Management Information Protocol and Services), X.400 (Message Handling System, or MHS), X.500 (Directory Service), Z39.50 (search and retrieval protocol used by WAIS), and many others. Apart from its actual application to real protocols, it also serves as a useful teaching model.

  • 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.
