  • detective constable — a police officer who investigates crime and who is of the lowest rank
  • development company — a company that buys land and builds houses, offices, shops, or factories on it, or buys existing buildings and makes them more modern
  • 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.
  • digital certificate — (communications, security)   An attachment to an electronic mail message used for security purposes, e.g. to verify that a user sending a message is who he or she claims to be, and to provide the receiver with the means to encode a reply. An individual wishing to send an encrypted message applies for a digital certificate from a certificate authority (CA). The CA issues an encrypted digital certificate containing the applicant's public key and a variety of other identification information. The CA makes its own public key readily available on the Internet. The recipient of an encrypted message uses the CA's public key to decode the digital certificate attached to the message, verifies it as issued by the CA and then obtains the sender's public key and identification information held within the certificate.
  • 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.
  • 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).
  • disaster capitalism — the practice (by a government, regime, etc) of taking advantage of a major disaster to adopt liberal economic policies that the population would be less likely to accept under normal circumstances
  • disciples of christ — a Christian denomination, founded in the U.S. by Alexander Campbell in the early part of the 19th century, that rejects all creeds, holds the Bible as a sufficient rule of faith and practice, administers baptism by immersion, celebrates the Lord's Supper every Sunday, and has a congregational polity.
  • displacement engine — any engine employing the rectilinear motion of one or more pistons in cylinders.
  • dobsonian telescope — a relatively inexpensive Newtonian telescope, suitable for visual but not photographic use, in which the tube assembly slips freely in the lower base.
  • double counterpoint — invertible counterpoint using two transposable voices.
  • draw the color line — to impose or accept the color line
  • duplicating machine — a duplicator, especially one for making identical copies of documents, letters, etc.

  • effervescent tablet — Effervescent tablets break down quickly when they are dropped into water or another liquid.
  • eilean donan castle — a castle near the Kyle of Lochalsh in Highland, Scotland: built in the 13th century; famous for its picturesque setting
