  • demon internet ltd. — (company)   One of the first company to provide public Internet access in the UK. The staff of Demon Systems Ltd., an established software house, started Demon Internet on 1992-06-01 and it was the first system in the United Kingdom to offer low cost full Internet access. It was started with the support of about 100 founder members who discussed the idea on Compulink Information Exchange, and were brave enough to pay a year's subscription in advance. They aimed to have 200 members in the first year to cover costs, ignoring any time spent. After about two weeks they realised they needed nearer 400. By November 1993 they had over 2000 subscribers and by August 1994 they had about 11000 with 20% per month growth. All revenues have been reinvested in resources and expansion of service. Demon link to Sprintlink in the United States making them totally independent. They peer with EUNet and PIPEX to ensure good connectivity in Great Britain as well as having links to the JANET/JIPS UK academic network. A direct line into the Department of Computing, Imperial College, London from their Central London Point of Presence (PoP) (styx.demon.co.uk) gives access to the biggest FTP and Archie site in Europe. Demon provide local call access to a large proportion of the UK. The central London PoP provides leased line connections at a cheaper rate for those customers in the central 0171 area. Further lines and PoPs are being added continuously. Subscribers get allocated an Internet Address and can choose a hostname within the demon.co.uk domain. They can have any number of e-mail address at that host. In October 1994 Demon confirmed a large contract with the major telecommunications provider Energis. They will supply guaranteed bandwidth to Demon's 10Mb/s backbone from several cities and towns. Several PoPs will be phased out and replaced with others during 1995. E-mail: <[email protected]>. Telephone: +44 (181) 349 0063. Address: Demon Internet Ltd., 42 Hendon Lane, Finchley, London N3 1TT, UK.

  • deoxyribonucleotide — an ester of a deoxyribonucleoside and phosphoric acid; a constituent of DNA.
  • department of labor — the department of the U.S. federal government that promotes and improves the welfare, opportunities, and working conditions of wage earners. Abbreviation: DOL.

  • design in real time — (programming)   (Dirt) A user interface builder for the X Window System by R. Hesketh.
  • dielectric constant — Electricity. the ratio of the flux density produced by an electric field in a given dielectric to the flux density produced by that field in a vacuum.
  • dielectric strength — the maximum voltage that can be applied to a given material without causing it to break down, usually expressed in volts or kilovolts per unit of thickness.
  • differential backup — (operating system)   A kind of backup that copies all files that have changed since the last full backup. Each differential backup will include all files in previous differential backups since the full backup so to restore a version of a file, you only need to search the full backup and the relevant differential backup. Some systems support differential backup by associating an "Archive" flag with each file and setting this flag whenever the file is modified to indicate that it should be included in the next backup. A differential backup does not change this flag, whereas an incremental backup resets it.
  • differential driver — (hardware)   An electronic device (commonly an integrated circuit), containing two amplifiers, used to drive a differential line.
  • digital electronics — (electronics)   The implementation of two-valued logic using electronic logic gates such as and gates, or gates and flip-flops. In such circuits the logical values true and false are represented by two different voltages, e.g. 0V for false and +5V for true. Similarly, numbers are normally represented in binary using two different voltages to represented zero and one. Digital electronics contrasts with analogue electronics which represents continuously varying quantities like sound pressure using continuously varying voltages. Digital electronics is the foundation of modern computers and digital communications. Massively complex digital logic circuits with millions of gates can now be built onto a single integrated circuit such as a microprocessor and these circuits can perform millions of operations per second.
  • digital linear tape — (storage)   (DLT) A kind of magnetic tape drive originally developed by DEC and now marketed by Quantum. DLT drives implement the Digital Lempel Ziv 1 (DLZ1) compression algorithm in a combination of hardware and firmware. They use a popular chip by Stac (now hi/fn) to do the string searching. Counting, sorting and Huffman coding are done in firmware (with hardware support for the Huffman algorithm?). In April 1997 DLT drives can transfer 5 megabytes per second and can store 35 gigabytes on a single cartridge. Compression might roughly double these figures.
  • dimethylnitrosamine — a yellow, water-soluble carcinogenic liquid, C 2 H 6 N 2 O, found in tobacco smoke and certain foods: known to be a potent carcinogen. Abbreviation: DMN, DMNA.
  • direct grant school — (in Britain, formerly) a school financed by endowment, fees, and a state grant conditional upon admittance of a percentage of nonpaying pupils nominated by the local education authority
  • directional coupler — (communications)   (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps).
  • dispersion relation — the relationship between the angular frequency (ω;) of a wave and the magnitude of its wave vector (k). Thus the wave's speed is ω/k

  • drink the health of — to salute or celebrate with a toast
  • educational adviser — a person who provides advice and training to teachers about teaching methods and educational policies
  • elastic deformation — In elastic deformation a material changes shape when a stress is applied to it but goes back to its original state when the stress is removed.
  • electroconductivity — Electrical conductivity.
  • electrode potential — the potential difference developed when an electrode of an element is placed in a solution containing ions of that element
  • electrodynamometers — Plural form of electrodynamometer.
  • electrohydrodynamic — (physics) Of or pertaining to electrohydrodynamics.
  • electronic keyboard — a typewriter keyboard used to operate an electronic device such as a computer, word processor, etc

  • halt and catch fire — (humour, processor)   (HCF) Any of several undocumented and semi-mythical machine instructions with destructive side-effects, supposedly included for test purposes on several well-known architectures going as far back as the IBM 360. The Motorola 6800 microprocessor was the first for which an HCF opcode became widely known. This instruction caused the processor to read every memory location sequentially until reset.
