  • 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.
  • 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
  • displacement engine — any engine employing the rectilinear motion of one or more pistons in cylinders.
  • do the decent thing — If you say that someone should do the decent thing, you mean that they should do something which they do not really want to do, but which you think they ought to do.
  • double-helical gear — herringbone gear.
  • drawing-room comedy — a light, sophisticated comedy typically set in a drawing room with characters drawn from polite society.
  • duplicating machine — a duplicator, especially one for making identical copies of documents, letters, etc.
  • electrocardiographs — Plural form of electrocardiograph.
  • electrocardiography — The measurement of electrical activity in the heart and the recording of such activity as a visual trace (on paper or on an oscilloscope screen), using electrodes placed on the skin of the limbs and chest.

  • galactic coordinate — Usually, galactic coordinates. a member of a system of coordinates that define the position of a celestial body with reference to the Milky Way.
  • gigabits per second — (unit)   (Gbps) A unit of information transfer rate equal to one billion bits per second. Note that, while a gigabit is defined as a power of two (2^30 bits), a gigabit per second is defined as a power of ten (10^9 bits per second, which is slightly less) than 2^30).

  • go round in circles — to engage in energetic but fruitless activity
  • goldbach conjecture — an unproved theorem that every even integer greater than 2 can be written as the sum of two prime numbers.
  • goods received note — a document created by a buyer on receipt of merchandise and which describes each good and details the quantity of each received
  • grand duke nicholas — of Cusa [kyoo-zuh] /ˈkyu zə/ (Show IPA), 1401–1464, German cardinal, mathematician, and philosopher. German Nikolaus von Cusa.
  • grandfather's chair — wing chair.
  • grandfather's clock — a pendulum floor clock having a case as tall as or taller than a person; tall-case clock; long-case clock.

  • gray-cheeked thrush — a North American thrush, Catharus minimus, having olive upper parts and grayish cheeks.
  • great crested grebe — a large Old World grebe, Podiceps cristatus, having black, earlike tufts of feathers projecting backward from the top of the head.

  • honorable discharge — a discharge from military service of a person who has fulfilled obligations efficiently, honorably, and faithfully.
  • horizontal encoding — (processor)   An instruction set where each field (a bit or group of bits) in an instruction word controls some functional unit or gate directly, as opposed to vertical encoding where instruction fields are decoded (by hard-wired logic or microcode) to produce the control signals. Horizontal encoding allows all possible combinations of control signals (and therefore operations) to be expressed as instructions whereas vertical encoding uses a shorter instruction word but can only encode those combinations of operations built into the decoding logic. An instruction set may use a mixture of horizontal and vertical encoding within each instruction. Because an architecture using horizontal encoding typically requires more instruction word bits it is sometimes known as a very long instruction word (VLIW) architecture.
