segment display
affichage m en segments

A segment display. Used with a light-emitting diode and a liquid-crystal display to show numbers from 0 to 9. Segments a, b, c, d, e, f, and g are tilted slightly to the right:
The patterns are as follows:

12345
6789

segmented program
programme m segmenté

A segmented program. A computer program written in sections that are called from the backing store on demand. A section may be overlayed after the previous section in the main store.

semiconductor
semiconducteur m

Semiconductor. A material that is not a good conductor of electricity like copper and is not a good insulator like plastic, but is in a position between the two positions and the way in which electricity is conducted can be changed by adding (called "doping") a small amount of another material (impurity).
For example: silicon is a semiconductor, when doped with a small amount of arsenic it provides additional negative electrons giving n-type silicon, while doping with phosphorus reduces the electrons giving p-type p. Other semiconductors include germanium and gallium arsenide.

sentinel
repère m de bande magnétique

Termination mark. A name given to a character or group of characters that has a special meaning, usually meaning that it is the last element of data. The terms terminator or rogue value have replaced this word.

serial access memory
serial access memory

Serial memory. Read/write memory is a set of locations that can only be accessed sequentially.

For example, to read a particular record stored on magnetic tape, you must go through all the records in succession to find it. Another example is bubble memory, although the access time is shorter here.

serial transmission
transmission f series

Serial transmission. This method involves sending each character or piece of data in turn, one after the other, along a wire instead of having a wire for each bit as in parallel transmission. Some standard interfaces for serial ports have been defined, including RS-232, V24, and RS-423.

seven-segment display
affichage m à seven segments

Seven-segment display See segment display.

shared files
file m comun

Shared files. Files stored in the computer's immediate access store and act as a file complex or backing store, and can be read, used and changed by other computers.

shift register
registre m à décalage

The location shift register on the computer is only used to shift data to the left or to the right. Note that shifting one place to the left in a decimal number is the same as multiplying the number by ten, although the first digit of the number is lost if the digits fill the position completely.

For example: In decimal numbers:
0472

The shift to the left is like multiplying by ten:
4720
And the shift to the right is like dividing by ten:
0047
And in binary notation:
0110 (6=)
The shift to the left is like multiplying by two:
1100 (12=)
And the shift to the right is like dividing by two: 0011 (3=)
