television receiver
recepteur m de télévision

Television receiver. The television set that most people have in their homes. This device usually receives the signal sent via an antenna or cable and converts the radio frequency signal (or, more accurately: the UHF signal) into image, color and sound. Most microcomputers have a socket that gives a signal suitable for displaying the output on a television receiver, but the device must be "tuned to the desired channel the first time it is done.

Some devices are monitors / receivers that have a second input socket that receives a video signal from the microcomputer. This provides a better picture, especially when displaying graphic details. To obtain the best color images, the red, green and blue signals are sent separately from each other, which requires a red, green and blue computer output and a red, green and blue monitor.

telex
télex m

Telex. A name given to a service that allows users to communicate with each other using a telephone network and a teleprinter.

terminal
terminal m

Terminal. A device connected to a computer that allows data to enter and exit. A terminal may be a touchpad, a remote writer (such as a teleprinter), or a visual display unit (VDU) and is often located remotely from the computer.

Example: Magnetic stripe card reader, a touchpad and display as in a bank cash dispenser, a barcode reader, or a cash register at the exit of a large supermarket.

A smart terminal has its own processing capability, while a dumb terminal does not.

terminator
caractère m d'arrêt

Attribute. Termination. A false value, such as a rogue value, at the end of a data set that signals to the computer that it is the last item. Termination attributes are similarly used on punched tape to indicate the end of each record.

tetrabyte (Tbyte)

tetraoctet m

Quad-byte. A term used to describe 1000 gigabytes or 1024 megabytes or the staggering 1073741824 bytes.

text editor
éditeur m de texte

Text editor. A piece of software often thought of as a limited word processing package. It is used to find, edit and format text files before printing. In addition, this software allows you to modify the order and content of any data set that the computer has created as part of the program. This is a quick way to add an entry in the middle of a set of records by moving each subsequent record down one step.

thin film memories
mémoires fpl minces

thin film memories. The name for integrated circuits (chips) made by depositing thin layers of patterns one on top of the other. The wafers are built up layer by layer, with the pattern of each layer determined by a specific mask. The process that uses ultraviolet light to define the pattern and thus the circuit is called photolithography. Today, X-rays and electron beams are used to define the pattern because, at shorter wavelengths, more circuits, and therefore more memories, can be placed on the same size wafer. Epitaxy is used with other semiconductors to make thin-film memories.
