stationery
papier m

Paper. Computer paper is usually continuous stationery. It consists of pages folded like fan folds connected to each other in perforated lines, and has sprocket holes along the edges. The company name may be pre-printed on the paper with space left on each page for computer printing. Single pages can be printed using single page feeders.

stepping motor
moteur m pas à pas

Stepping motor. Compared to a regular electric motor, this motor rotates one step at a time so that it takes 96 steps in one revolution, for example. The manufacturer determines the number of steps, and it depends on the number of file groups and the number of files in each group. If there are 4 groups of files, each with 12 files, the possible positions are 48 positions, and 96 steps can be obtained by stopping halfway between the two positions. The motor moves from one position to another by operating different sets of coils in turn and using a sequence of numbers that can be provided by the digital output of the computer. This is an important method for generating precise movement under the control of the microprocessor and is commonly used in robotics.

store
mémoire f

store. A name given to anything that stores data provided by the central processing unit in a computer. Core store, memory chips, bubble memory, magnetic disk, drum, and tape are just a few types of stores. The size of the store depends on the number of memory locations.

string
chaine f

set. The word set is used to describe a collection of characters that may actually be no more than one character. While numbers are stored in fixed lengths of memory with spaces filled with zeros, characters are used in groups of different lengths. These are stored in a series of memory locations, with the first location holding a number that specifies the length of the array (number of attributes). BASIC uses the dollar sign $ along with the variable to indicate that it is an array. For example: $HELLO = A, and this word can be stored in six locations, the first holding the number 5.

stripware
fpl data on tape

Soft tape content. A term used to describe data stored or distributed on a soft strip.

structured programming
programming f structurée

Structural programming. The art of writing logical and easy-to-follow programs. It involves dividing the original problem into small programming units, each of which is independent and can be tested separately. The main program can then consist of a series of instructions, each of which directs the computer to a specific unit or subroutine to execute and then return.

Instructions such as REPEAT... UNTIL, FOR... NEXT, and DO... WHILE allow for easy structure while writing the program. Using the top-down approach, the program is written in units in the same way that the original problem was solved. It can be said that contextual data flow charts are not required in this approach. However, the programming must be well-structured to be written without contextual data.

subroutine
sous programme m

approach. A section of a program written to perform a specific task that the main program can use once or multiple times during execution. Typically, the last instruction in the procedure returns the computer to the instruction that follows the one at which the main program left. Large computer systems have a set of procedures on disk or tape that can be called by the running program and used whenever and however needed. A procedure is a form of procedure that can be called by the programmer once or multiple times during a program. The main difference between the two is that it is called by name and must be specified (written) outside the main body of the program. It can also have its own variables.

synchronous mode
mode m synchrone

synchronous mode . A computer's performance in which the start of each operation depends on a pulse from its internal clock. Thus, the completion of one task does not signal the start of the next task, as is the case in the asynchronous mode, where the machine waits, even for a fraction of a second, for the next clock pulse.

syntax
syntaxe m

Syntax Principles Just as the words we speak need a certain grammatical system to be understood, the instructions given to the computer must adhere to certain rules. The machine reports a “syntax error” when the programmer makes mistakes in the instructions.

For example: The instruction

10 INPUT A:B
in BASIC language leads to a syntax error because it should be
10 INPUT A,B

and here the rules for writing program instructions were not adhered to.
