  • 1nf — database normalisation
  • 610 — (communications)   The standard type of two-wire wall socket and plug used for telephones in Australia.
  • 8n1 — (jargon)   Common shorthand for "eight data bits, no parity, one stop bit", the most common configuration for serial lines, e.g. EIA-232.
  • a-1 — noting a vessel regarded by a shipping-classification society as being equipped to the highest standard and with equipment maintained in first-class condition.
  • a1c — airman first class
  • b-1 — a U.S. long-range bomber, having sweptback wings and a subsonic cruising speed.
  • dc1 — control-Q
  • ds1 — (communications)   A DS level and framing specification for synchronous digital streams, over circuits in the North American digital transmission hierarchy, at the T1 transmission rate of 1,544,000 bits per second (baud). DS1 is commonly used to multiplex 24 DS0 channels. Each DS0 channel, originally a digitised voice-grade telephone signal, carries 8000 bytes per second (64,000 bits per second). A DS1 frame includes one byte from each of the 24 DS0 channels and adds one framing bit, making a total of 193 bits per frame at 8000 frames per second. The result is 193*8000 = 1,544,000 bits per second. In the original standard, the successive framing bits continuously repeated the 12-bit sequence 110111001000, and such a 12-frame unit is called a super-frame. In voice telephony, errors are acceptable (early standards allowed as much as one frame in six to be missing entirely), so the least significant bit in two of the 24 streams was used for signaling between network equipments. This is called robbed-bit signaling. To promote error-free transmission, an alternative called the extended super-frame (ESF) of 24 frames was developed. In this standard, six of the 24 framing bits provide a six bit cyclic redundancy check (CRC-6), and six provide the actual framing. The other 12 form a virtual circuit of 4000 bits per second for use by the transmission equipment, for call progress signals such as busy, idle and ringing. DS1 signals using ESF equipment are nearly error-free, because the CRC detects errors and allows automatic re-routing of connections. Compare T-carrier systems.
  • el1 — Extensible Language One. An extensible language by B. Wegbreit of Harvard ca 1974. EL1 is internally somewhat Lisp-like, but fully typed with records and pointers. The external syntax is ALGOL-like and extensible, supporting user-defined data structures, control structures and operations. The parser is table-driven, with a modifiable set of productions. Used as the basis for the ECL operating system.
  • g10 — Group of Ten
  • if1 — (language)   A graph language used as an intermediate language for dataflow hardware. Used by the OSC SISAL compiler.
  • kl1 — Kernel Language 1. An experimental AND-parallel version of KL0 for the ICOT project in Japan. KL1 is an implementation of FGHC. Not to be confused with KL-ONE.
  • m-1 — a semiautomatic, gas-operated, .30 caliber, clip-fed rifle, with a weight of 8.56 pounds (3.88 kg): the standard U.S. Army rifle in World War II and in the Korean War.
  • mp1 — MPEG-1 audio layer 1
  • n10 — Original codename of the Intel i860 microprocessor.
  • ne1 — anyone
  • no1 — no-one
  • nt1 — Network Termination
  • pl1 — (spelling)   It's spelled "PL/I".
  • tl1 — Transaction Language 1. A subset of ITU-T's MML from Bellcore, with simpler syntax. TL1 is similar to USL. It is used in communications between telephone operating systems and remote network test equipment.
  • v-1 — a robot bomb developed by the Germans in World War II and launched from bases on the ground, chiefly against England.
  • x-1 — (language)   An early system on the UNIVAC I or II.
  • zt1 — Zimmerman Thunder 1
