- 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).
- 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.

- 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.
- elastomeric closure — An elastomeric closure is a component that closes a piece of packaging. An elastomeric closure is made from a material that is able to resume its original shape when it is removed from the packaging and may be in direct contact with the drug enclosed in the pack.
