chip
puce f

Chip. is the common name for the integrated circuit. It is a solid state circuit in which all its components are formed on a single piece of semiconductor material. The first chip (1959) consisted of a transistor and a resistor. Since then, the number of components on the chip has doubled approximately every year. The term large-scale integration (LSI) means that the integrated circuit has more than 100 logic gates or more than 100 bits of memory.

CIM

Computer Integrated Manufacturing. Abbreviation - computer inte grated manufacture.

CISC (complex instructions set computer)
ordinateur m CISC

Complex instruction set computer. A term used to describe the development of computers that still rely on increasingly complex microprocessors, where a single machine code instruction is ultimately translated from a single high-level language instruction. This means that microprocessors are designed to use thousands of machine code instructions, regardless of how little they may be used. In contrast, modern RISC microprocessors with simpler designs have higher speeds and can match current software and execute it much faster.

clock
horloge f

A timer. An electronic device that emits pulses at fixed, specific intervals. These pulses can be used to control computer operations so that they are all synchronous. The clock pulses are generated by multiple astable oscillators.

CM

mémoire f centrale
Central memory. Abbreviation for central memory.

CML (computer-managed learning)

See computer-assisted learning.

CMOS

Complementary metal oxide semiconductor.

Abbreviation for -com. plementary metal oxide semiconductor

coaxial cable
cable m coaxial

Coaxial cable. A cable containing two or more conductive wires, each insulated and surrounded by the one before it. Examples: a television antenna cable and cables that connect a network of computers in a school or other place.

COBOL

COBOL is abbreviation for Common Business Oriented Language. It is a high-level language developed in America in 1959 for general business programming.

code
code m

كود. A term used to describe a set of computer programming instructions, although it can also refer to binary patterns used to represent characters.

coded number
nombre m codé

A coded number is the registration number of something, and can be placed, or encoded, in a particular way to conform to a company's or organization's computer system. Coded numbers can be verified by checksum or weighted check digit methods.

COM

microfilm m de sortie d'ordinateur

computer output on microfilm. Abbreviation for computer output on microfilm, a process that aims to convert computer output directly to a microfiche or film, especially 35 mm and 16 mm film.

COMAL
COMAL

COMAL. A high-level language derived from both BASIC and Pascal.

compact disc - interactive (CD - I)
disque m compact interactive

Interactive compact disc. A compact disc (optical disc about 5 inches in diameter) allows both reading and writing, making it interactive with the user.

New programs and data are "burned" onto the surface of the disc as depressions created by a powerful laser. A weak laser is passed over the surface, and the data is distorted by the reflection of the depressions. It is currently difficult to erase the contents of the disc surface and restore it to a completely smooth state. WORM (write once read many times) technology overcomes this problem by writing new or revised data onto unused parts of the disc and making any previous contents inaccessible, giving the appearance of re-storing programs or data. Because CDs have a capacity of 600 megabytes, it may take a long time before the entire disc is used and another disc is needed.
