- message passing interface — (communications, protocol) A de facto standard for communication among the nodes running a parallel program on a distributed memory system. MPI is a library of routines that can be called from Fortran and C programs. MPI's advantage over older message passing libraries is that it is both portable (because MPI has been implemented for almost every distributed memory architecture) and fast (because each implementation is optimised for the hardware it runs on).
- metal-free phthalocyanine — phthalocyanine (def 1).
- minimal brain dysfunction — (no longer in technical use) attention deficit disorder.
- mpc level 1 specification — (multimedia) The original Multimedia Personal Computer specification. Minimum requirements are a 16 MHz 386SX with 2 megabytes of RAM, a 30 MB hard disk drive, and a CD-ROM drive with a sustained data transfer rate of 150 KB/s at no more than 40% of CPU bandwidth and reading at least 16 KB blocks. The maximum average seek time is 1 second and the Mean Time Between Failure 10000 hours. Capability Mode 1. The computer must have 8-bit digital sound and an 8-note synthesizer with MIDI playback. Sample rates of 22.05 and 11.025 kHz must be supported by no more than 10% of CPU bandwidth, preferably 44.1 kHz at no more than 15% of CPU bandwidth. The synthesizer must support multi-voice, multi-timbral generation of six simultaneous melody notes and two simultaneous percussive notes with internal mixing capabilities to combine input from three sources and present the output as a stereo, line-level audio signal at the back panel. The video display must have a resolution of at least 640 x 480 in 16 colours. MIDI, I/O, and joystick ports must be previded. Compare MPC Level 2 Specification.
- mpc level 2 specification — (multimedia) An improved version of the MPC Level 1 Specification for Multimedia Personal Computers. Minimum requirements are a 25 Mhz 486SX with 4 MB of RAM and a 160 MB hard disk drive. The CD-ROM drive must support a sustained data transfer rate of 300 KB/s using at most 60% of CPU bandwidth on 16 KB minimum block read size. Its average seek time must be 400 milliseconds maximum. Capability Mode 1, Mode 2 form 1, Mode 2 form 2, Multisession. It must be CD-ROM XA-ready. The computer must have 16-bit digital sound, an 8-note synthesizer, and MIDI playback. A sample rate of 44.1 kHz must be available on stereo channels with more than 15% of CPU bandwidth. A video display with a resolution of 640 x 480 in 65,536 colours, and MIDI, I/O, and joystick ports must be provided.
- non-uniform memory access — (architecture) (NUMA) A memory architecture, used in multiprocessors, where the access time depends on the memory location. A processor can access its own local memory faster than non-local memory (memory which is local to another processor or shared between processors).
- of someone's acquaintance — A person of your acquaintance is someone who you have met and know.
- office of war information — OWI.
- 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 wingback formation — an offensive formation in which the wingback lines up outside of and about one yard behind an end, the quarterback lines up lateral to the wingback but about midway between the same end and the center, the fullback is three or four yards behind the middle of the line, and the tailback lines up one yard behind the fullback on the other side of the line from the wingback and quarterback.
- single-lens reflex camera — a camera in which the image appears on a ground-glass viewer (focusing screen) after being reflected by a mirror or after passing through a prism or semitransparent glass; in one type (single-lens reflex camera) light passes through the same lens to both the ground glass and the film, while in another type (twin-lens reflex camera) light passes through one lens (viewing lens) to the ground glass and through a second lens (taking lens) to the film, the lenses being mechanically coupled for focusing.
- specific fuel consumption — Specific fuel consumption is the amount of fuel consumed by a vehicle for each unit of power output.
- the calm before the storm — You can use the calm before the storm to refer to a quiet period in which there is little or no activity, before a period in which there is a lot of trouble or intense activity.

- thermoelectromotive force — the electromotive force developed by the thermoelectric effect.
- time domain reflectometer — (hardware, networking) (TDR) An electronic device for detecting and locating short- or open-circuits in an Ethernet cable. TDRs can also measure how the characteristic impedance of a line varies along its length.
- to catch sight of someone — If you catch sight of someone, you suddenly see them, often briefly.
- to someone's satisfaction — If you do something to someone's satisfaction, they are happy with the way that you have done it.

- 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.
- uniform naming convention — Universal Naming Convention
- uniform resource citation — (web) (URC) A set of attribute/value pairs describing an object. Some of the values may be URIs of various kinds. Others may include, for example, athorship, publisher, datatype, date, copyright status and shoe size. A URC is not normally considered as a string, but a set of fields and values with some defined free formatting.
