  • pci configuration utility — (tool)   (PCU) A piece of software for configuring a specific PCI hardware device.
  • permanent virtual circuit — (networking)   (PVC, or in ATM terminology, "Permanent Virtual Connection") A virtual circuit that is permanently established, saving the time associated with circuit establishment and tear-down.
  • pharmacotherapeutic group — Drugs and agents are categorized into pharmacotherapeutic groups based on which diseases they are designed to treat.
  • point-and-grunt interface — point-and-drool interface
  • pressurized-water reactor — a nuclear reactor using water as coolant and moderator at a pressure that is too high to allow boiling to take place inside the reactor. The fuel is enriched uranium oxide cased in zirconium
  • primary producing country — a country that is involved in the extraction or winning of products consisting of raw materials, as in agriculture, fishing, forestry, hunting, or mining
  • principle of virtual work — the principle that the total work done by all forces on a system in static equilibrium is zero for a set of infinitesimally small displacements.
  • property damage insurance — insurance against losses arising from damage to the property of others, as in a motor-vehicle accident.
  • public inter national law — Also called public law. the law governing the legal relations between independent states or nations and, increasingly, between these and individuals.
  • public key infrastructure — (cryptography, communications)   (PKI) A system of public key encryption using digital certificates from Certificate Authorities and other registration authorities that verify and authenticate the validity of each party involved in an electronic transaction. PKIs are currently evolving and there is no single PKI nor even a single agreed-upon standard for setting up a PKI.

  • public relations exercise — something which is done for the sake of attracting favourable publicity
  • radio-controlled junction — A radio-controlled junction is a piece of equipment used to control underground pipelines which connect oil tanks.
  • rate monotonic scheduling — (algorithm)   A means of scheduling the time allocated to periodic hard-deadline real-time users of a resource. The users are assigned priorities such that a shorter fixed period between deadlines is associated with a higher priority. Rate monotonic scheduling provides a low-overhead, reasonably resource-efficient means of guaranteeing that all users will meet their deadlines provided that certain analytical equations are satisfied during the system design. It avoids the design complexity of time-line scheduling and the overhead of dynamic approaches such as earliest-deadline scheduling.
  • saybolt universal seconds — a US measurement of viscosity similar in type to the British Redwood seconds
  • sequential parlog machine — (SPM) The virtual machine (and its machine code) for the Parlog logic programming language.
  • single document interface — (programming)   (SDI) A limitation applying to an application program that only shows a single windows giving a view of one document at a time. The opposite is Multiple Document Interface (MDI).
  • single electron tunneling — (electronics)   (SET) A New electrical standard for capacitance. SET devices can be used to construct circuits which process information by manipulating individual electrons. SET devices are small, dissipate little power, and can detect exquisitely small quantities of charge. The small size and low power dissipation of SET circuits makes them potentially useful for the Information Technology industry.
  • software through pictures — (programming, tool)   (StP) A set of CASE tools distributed by Aonix.
  • strong accumulation point — a point such that every neighborhood of the point contains infinitely many points of a given set.
  • subordinating conjunction — a conjunction introducing a subordinate clause, as when in They were glad when I finished.
  • subscriber trunk dialling — a service by which telephone subscribers can obtain trunk calls by dialling direct without the aid of an operator
  • sulphate-resisting cement — a type of Portland cement that resists normal concentrations of sulphates: used in concrete for flues and underwater work
  • the ball is in sb's court — If you say that the ball is in someone's court, you mean that it is his or her responsibility to take the next action or decision in a situation.
  • the ball is in your court — you are obliged to make the next move
  • thermodynamic equilibrium — the condition of an isolated system in which the quantities that specify its properties, such as pressure, temperature, etc, all remain unchanged
  • thermodynamic temperature — temperature defined in terms of the laws of thermodynamics and not in terms of the properties of any real material. It is usually expressed on the Kelvin scale
  • thermoluminescence dating — a method of dating archaeological specimens, chiefly pottery, by measuring the radiation given off by ceramic materials as they are heated.
  • town-and-country planning — a system of government planning used to plan how land should be used, balancing economic development and environmental quality
  • tribasic sodium phosphate — sodium phosphate (def 3).
  • ucs transformation format — (standard, character)   (UTF) A set of standard character encodings in accordance with ISO 10646. One of a set of standard character encodings, the most widely used of which are UTF-8, UTF-16, and UTF-32. The code tables in ISO 10646 and in the Unicode standard are identical, although the Unicode standard includes additional material. UTF-8 is the most widely used encoding, at least on Unix systems. Since it does not include any bytes like '\0' or '/' which have a special meaning in filenames and other C library function parameters, and 7-bit ASCII characters have the same encoding under both ASCII and UTF-8, the required changes to existing software are minimised. Other UTFs: UTF-1 and UTF-7 are not widely used.
  • unconditional convergence — the property of a convergent infinite series that remains convergent when the terms are arranged in any order.
