block
bloc m

Built-in. A set of records, figures, or words that a computer treats as a single unit of
data.
For example: A microcomputer's data is transferred to and from a cassette tape recorder in blocks. These blocks are sometimes referred to by numbers that appear on the screen, although they can be distinguished by listening to them directly by rotating the tape.

block diagram
schema m bloc

Built-in diagram. A diagram used to help explain a system and consists of labeled frames connected by lines with arrows similar to the flowchart of a program's context statement. This diagram uses systems such as electrical circuits.

Boolean algebra
algèbre f de Boole

Boolean algebra. English: The English mathematician George Boole (1864 - George Boole (1815 -) was the first to introduce this algebra to the world in 1847. It is a set of rules that allow logical expressions to be written using algebra. The results of these expressions can be shown in a truth table.

bootstrap
amorçage m

Bootstrap. Running a program on a computer, such as pressing a certain key that first calls one or more methods that must be used to run the programs. Turning on the computer does not mean that it is ready, and (booting) the system usually gives the computer user a form of an operating system.

branch
branchement m

Branch. The computer executes each step of the program in sequence, but it can jump to a different part of the program by means of a branch instruction.

For example: A conditional branch may depend on the value of something at a certain time, such as branching if the value of x is greater than 7. Structured programming avoids the use of branching

breadboard
experimental montage

Breadboard. An experimental circuit board used to test circuits, often included in the learning/education assembly of a microprocessor for interfacing and control technology.

broadband
bande f large

Broadband. A transmission technology that uses a wide range of frequencies to allow telecommunications messages to be sent simultaneously. See also data communications.

BSI

British Standards Institution.

Abbreviation for British Standards Institution.
The body that sets and maintains standards for units of measurement, technical terminology, etc., in the United Kingdom.

bubble memory
mémoire f à bulle

Bubble memory. Used to store data in binary notation, where small magnetic cylinders, called bubbles, are held in place by magnets in an integrated circuit (or chip) made of magnetic material. Each bubble is used to represent the number 1, and the absence of a bubble means 0.

To keep the bubbles in place, chevrons are placed on the surface of the slip (shown in Figure 7 in the figure). The bubbles are at one end and are moved by magnetic fields not shown in the figure across the slip as required and read in sequence. This is a serial access memory, but its advantages are that it is non-volatile and capable of high-density storage. This entire book, represented by 1s and 0s, can be stored on four bubble memory slips, each less than a square centimeter in size.

buffer
tampon m

buffer. A temporary storage for data being transferred, usually used to allow for varying speeds.

For example, what is printed on a microcomputer touchpad is generally stored in a buffer until the return or enter key is pressed. Many printers have cartridges that fill with what needs to be printed much faster than the actual printing speed.
