19-letter words containing o, i, l, n, a, r
- 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.
- 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.
- 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).
- disciplinary action — punishment or caution
- 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
- diversional therapy — the structured use of leisure time in recreation and play as a form of or supplement to conventional therapy
- draw the color line — to impose or accept the color line
- drill-down analysis — drill down
- drink the health of — to salute or celebrate with a toast
- dynamic translation — (architecture) A virtual machine implementation approach, used to speed up execution of byte-code programs. To execute a program unit such as a method or a function, the virtual machine compiles its bytecodes into (hardware) machine code. The translated code is also placed in a cache, so that next time that unit's machine code can be executed immediately, without repeating the translation. This technique was pioneered by the commercial Smalltalk implementation currently known as VisualWorks, in the early 1980s. Currently it is also used by some implementations of the Java Virtual Machine under the name JIT (Just In Time compilation).

- fault tolerant unix — (operating system) (FTX) Stratus's own Unix System V Release 4 multiprocessor operating system. In 2016, FTX is supported but no longer developed. FTX was one of three operating systems supplied by Stratus on their hardware, the other two, HP-UX and VOS, were the more common choices, FTX was only sold on an exceptional basis. Early FTX 3.x releases used an in-house virtual disk layer (VDL) driver, but later releases switched to a version of Veritas VxVM. FTX supported many of the proprietary communications boards (ISDN, serial, parallel, X.25, etc.).
