decimal
décimal

Decimal. An integer between 0 and 9 used in decimal notation. When working with the decimal system (base 10), we use the numbers from 0 to 10 minus 1, i.e. 9, and when working with another base, say 6, we use the numbers from 0 to 6 minus 1, i.e. 5. In the binary system (base 2), we only use 0 and 1.

decision box
symbole m de décision

Decision symbol. A diamond-shaped symbol used in a flow chart to indicate a directional choice. The choice usually depends on the value of the variable.

For example:
Give me a number between 1 and 90
Divide by 2
Yes
The number and see
Is there a remainder?
No
Number even
Decision box

decoder
decodeur m

Decoder A tool used to change data from one encoded format to another. For example: An instruction in a program such as PRINT is stored in binary form, and because it is so, its code must be decoded by logic circuits before it can be executed.

denary notation
notation f décimale

Decimal notation. Our normal number system, where we count in tens using the decimal system. The numbers from 0 to 9 are used in the ones column and then we move to the tens column.

desktop publishing (DTP)
éditeur m de bureau

Desktop publishing. A method of producing reports, brochures and magazines of professional quality using a computer and peripheral devices. A desktop publishing system usually consists of a computer, a mouse, a laser printer and accompanying software (an integrated word processing and graphics and page layout programs). More sophisticated systems also include a scanner to produce black-and-white images. Graphics and text can be combined into a magazine format with a variety of features and titles, and within a few years standard word processing programs may contain all the features of desktop publishing.

diagnostic routine
sous - programme m de diagnostic

A diagnostic approach. A program given with a computer and used to track errors in programs or to monitor malfunctions in the machine itself. It is useful for debugging programs.

digit
chiffre m

Number. Any of the numbers from 0 to 9, noting that a number such as 747 has three digits but only two different characters. For a computer, the number is considered part of the data.

digital computer
ordinate m numérique

A digital computer. This type of computer only works with data represented in digital form, usually binary form consisting of zeros 0 and ones 1. This computer differs from an analog computer in that it can store large amounts of data and can calculate with great accuracy.

digitiser
digitaliseur m

Digitizer. A device that converts analog signals into digits. That is, it is an analog to digital converter (A to D).

For example: In order for a computer to record temperatures, one must connect a temperature recorder to the computer via a digitizer. When the temperature rises, there is a continuous increase in voltage input to the digitizer, which the computer scans repeatedly. The computer records the increases in specific jumps and stores the data as digits. Although the jumps can be made very small (which gives greater precision and more meaningful numbers), they are always present in the computer data.

DIN

Abbreviation for Deutsche Industrie - Norm, the German equivalent of the British Standards Institution (BSI). Its industry standard for plugs, sockets, and cables for connecting audio and video equipment has now been expanded to cover computer terminals and peripherals.

direct - access storage
memory for direct access

Direct Nile storage. Unlike serial access, direct Nile storage can be accessed very quickly and without having to go back to previous Nile sites. This storage is sometimes called random-access memory (RAM), as data or programs can be accessed almost instantly without having to start sequentially from the beginning.
