- operational amplifier — a high-gain, high-input impedance amplifier, usually an integrated circuit, that can perform mathematical operations when suitably wired.
- operational semantics — (theory) A set of rules specifying how the state of an actual or hypothetical computer changes while executing a program. The overall state is typically divided into a number of components, e.g. stack, heap, registers etc. Each rule specifies certain preconditions on the contents of some components and their new contents after the application of the rule. It is similar in spirit to the notion of a Turing machine, in which actions are precisely described in a mathematical way. Compuare axiomatic semantics, denotational semantics.
- ophthalmia neonatorum — inflammation of the eyes of a newborn child due to an infectious disease, as gonorrhea, contracted during birth from the infected mother.
- partial reinforcement — the process of randomly rewarding an organism for making a response on only some of the occasions it makes it

- peephole optimisation — (compiler) A kind of low-level code optimisation that considers only a few adjacent machine code instructions at a time and looks for certain combinations which can be replaced with more efficient sequences. E.g. ADD R0, #1 ADD R0, #1 (add one to register R0) could be replaced by ADD R0, #2 as long as there were no jumps to the second instruction.
- peephole optimization — peephole optimisation
- piezoelectric ceramic — any ceramic that exhibits piezoelectric properties.
- politically motivated — If an act of violence is politically motivated, it is carried out in the interests of a particular government or political party.
- portable commodore 64 — (computer) A version of the Commodore 64 modelled after the original Osborne portable PCs, with a flip-down keyboard that revealed a 5-inch colour monitor, and a built-in 1541 floppy disk drive. It is thought that few were made but that they did go on sale, at least in Canada.

- propantheline bromide — a substance, C 2 3 H 3 0 BrNO 3 , used in the treatment of peptic ulcers.
- pulse code modulation — a form of modulation that transforms a wave-form, as an audio signal, into a binary signal in which information is conveyed by a coded order of pulses for transmission, storage on a disk, or processing by a computer. Abbreviation: PCM.
- pulse-code modulation — a form of modulation that transforms a wave-form, as an audio signal, into a binary signal in which information is conveyed by a coded order of pulses for transmission, storage on a disk, or processing by a computer. Abbreviation: PCM.
- pulse-time modulation — radio transmission in which the carrier is modulated to produce a series of pulses timed to transmit the amplitude and pitch of a signal. Abbr.: PTM.
- quantum teleportation — a hypothetical technique to instantly transfer properties from one quantum system to another without contact, or to transfer a quantum state to an arbitrarily distant location.
- real operating system — (operating system, abuse) The sort the speaker is used to. People from the BSDophilic academic community are likely to issue comments like "System V? Why don't you use a *real* operating system?", people from the commercial/industrial Unix sector are known to complain "BSD? Why don't you use a *real* operating system?", and people from IBM object "Unix? Why don't you use a *real* operating system?" See holy wars, religious issues, proprietary, Get a real computer!.
- redevelopment company — a private corporation or a public agency that stimulates the improvement of land, as through a building project subject to certain designs and controls, by financing, selling, or leasing such real estate to interested buyers or lessees.
- remote procedure call — (networking, programming) (RPC) A protocol which allows a program running on one host to cause code to be executed on another host without the programmer needing to explicitly code for this. RPC is an easy and popular paradigm for implementing the client-server model of distributed computing. An RPC is initiated by the caller (client) sending request message to a remote system (the server) to execute a certain procedure using arguments supplied. A result message is returned to the caller. There are many variations and subtleties in various implementations, resulting in a variety of different (incompatible) RPC protocols.
- remote write protocol — (chat, protocol) (RWP) A proposed Internet protocol for exchanging short messages between terminals. The RWP proposal is detailed in RFC 1756.
- replacement algorithm — The method used to determine which entry in an associative cache to flush to main memory when it is desired to cache a new block of data. The "least recently used" algorithm flushed the block which has not been accessed for the longest time. A random replacement algorithm picks any block with equal probability.
