insulator
isolant m

Insulator. A material with high resistance to electrical current so that the current passing through it can be ignored. One of the best known insulators is silicon dioxide, which is generated on the surface of silicon by heating.

integrated circuit (IC)
circuit m intégré

integrated circuit. A solid state circuit in which all its components are located on a single piece of semiconductor material. Large scale integration (LSI) means an integrated circuit with more than 100 logic gates or more than 1000 bits of memory. Also called a chip.

integrated services digital network (ISDN)

réseau m numérique de télécommunications

Integrated Services Digital Network. An information system based on signals that allow data, voice, video, image (fax) and e-mail to be sent over the same wires. Fibre optics and microwave relays will be used in all services provided, providing a wide range of wavelengths. Conventional copper wires are known to have narrow wavelengths. See also: data communications.

intelligent terminal
terminal m intelligent

A terminal with its own processing capacity that allows data to be processed without resorting to a computer again.

Intelsat
Intelsat

Intelsat. A group of communications satellites managed by the International Satellite Telecommunications Consortium, from which the name comes.

interactive video (IV)
video m interactif

Interactive video. A system consisting of a computer, an optical disk, a video and a monitor. The teacher or trainer can prepare the study material from texts, diagrams and numbered images stored on an optical disk. A video recorder can be used to provide film images when required.

The student benefits in this case from an individual lesson tailored to his or her needs. The computer uses the student's answers as feedback to decide what teaching method is most appropriate. Interactive video is expected to have a major impact on education. The system is currently being tested in pilot schools. It is expected that there will be a large market for computer-mediated education in industry and commerce.

interface
interface f

A circuit board (or hardware) necessary to establish communication between two devices. This circuit board may compensate for differences in speed or transmission rates or may translate codes. Often the type of transmission is what must be changed and the interface is connected to one of the devices. Communication between such devices is called a response.

interpreter
interpréteur m

Interpreter. A type of program that checks, translates, and executes a written program, sentence by sentence. Most microcomputers

are equipped with a BASIC interpreter which, although it serves most purposes, is much slower to execute than a BASIC compiler.

interrupt
interruption f

Interruption. A system in which a peripheral device can stop the computer from its current task and use it to transfer data to or from the peripheral device. The computer then resumes its work.

inverted file
fichier f inversé

Inverted file. A method of arranging a file so that groups are identified by "keys". This makes retrieving different groups much faster than by searching each record in a conventional way. As information retrieval becomes more widely used, file inversion becomes more important. See also sort .

inverter
inverseur m

Reverse . See NOT gate .

I/O
entrée/ sortie

Input/output . See input/output .

IP

information provider .

Abbreviated information provider , i.e. the source from which the computer obtains information .

ISBN

International Standard Book Number .

ISDN

ISO
organisation f internationalle des normes

International Organization for Standardization Abbreviation for International Standards Organization, an organization founded in 1947 and headquartered in Switzerland that oversees the standardization of units of measurement, industrial standards and technical terminology including computer terminology.

IT
technologie f de l'information

Abbreviation for information technology.

iteration
itération f

Iteration. A mathematical process by which one can obtain an answer that he uses to obtain a more accurate answer. Then he uses the new answer to obtain a better answer.. and so on.

IV

Abbreviation for interactive video.
