19-letter words containing a, l, t, r, s, o
- commercial software — (software) (Or "commercial off-the-shelf software", COTS) Software that is produced for sale. This contrasts with free software, which is produced for free distribution, meaning without charge and/or without restriction on further distribution. Some companies that sell software distribute some (versions) of products free of charge (but usually with restricted distribution rights), this would probably still be called commercial software. Conversely, software that an individual distributes for free, but for which he accepts donations, would still be called free software.

- core protocol stack — (architecture) 1. A portion of the Web Services architecture for defining and describing various Web Services. 2. The architectural protocol layers of a Bluetooth wireless communication system, comprising the Host Control Interface (HCI), Logical Link Control and Adaptation Protocol (L2CAP), RS232 Serial Cable Emulation Profile (RFCOMM), Service Discovery Protocol (SDP), and Object Exchange (OBEX).

- de-militarised zone — (networking) (DMZ) (From the military term for an area between two opponents where fighting is prevented) DMZ Ethernets connect networks and computers controlled by different bodies. They may be external or internal. External DMZ Ethernets link regional networks with routers to internal networks. Internal DMZ Ethernets link local nodes with routers to the regional networks. Compare red zone.
- deflate compression — deflate

- 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

- diversional therapy — the structured use of leisure time in recreation and play as a form of or supplement to conventional therapy
- 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).
