remote control
télécommande f

Remote control. These devices are currently used to operate televisions, video recorders and some devices. Prestel Using a weak beam of infrared rays (like a beam of light but our eyes do not see it), these tools enable a person to operate a machine from different distances by means of a hand-held switch box. In a similar way, one can operate a computer while sitting in his seat.

remote job entry (RJE)
télésoumission f de travaux

Entering tasks remotely. In batch processing, programs to be placed on the computer can be entered either from the computer itself or from a number of remote locations, and this term refers to the second case.

re- run
reprise f d'execution

Re-execution. Executing a computer program again with the original data starting from the beginning.

reserved word
mot m réservé

A dedicated word. Generally, a word that has a specific meaning to the compiler, and therefore should not be used by the programmer when programming in a high-level language.

response time
temps m de réponse

Response time. The time it takes for the computer to respond after the last key is pressed. This time is very short in the case of a microcomputer but varies greatly when a mainframe computer is accessing a terminal. The time includes transmission in both directions and depends on the number of other users. The response time for multi-access processing systems should not exceed five seconds.

RGB

Abbreviation for red, green, blue .

right justification
justification f à droite

Right shift . Arranging lines of text so that the right ends of the lines are justified and placed on a single vertical row. However, this term can also refer to data stored in consecutive positions, all filled on the right side, although there may be different numbers of spaces on the left side.

right shift
décalage m à droite

Right shift In this operation, all characters in a string are moved one space to the right. If it is a number, the shift has the effect of division. For example, just as moving a decimal number one place to the right means dividing it by ten, so moving a binary number means dividing it by two:

768.0 in decimal becomes 76.8
(26 =) 11010 in binary becomes (13 =) 1101

RISC (reduced instruction set computer)
RISC computer

Reduced instruction set computer. It is assumed that most users spend 80 percent of their time using 20 percent of the microprocessor's instructions. This justifies creating a computer with a microprocessor in which only the most frequently used instructions are programmed. These basic instructions are then used as building blocks and combined to form more complex tasks. The goal of keeping these building blocks clear, simple, and easy is to execute the instruction as quickly as possible. Reduced instruction set computers have speeds starting at 3 million instructions per second. This is in contrast to CISC microprocessors, where complexity slows down the workflow.

Reduced instruction set microprocessors can also enable emulation of different computer instruction sets. The speed of software execution can be multiplied many times over, and high-level languages ​​such as Pascal and C can be easily ported across different computers.

Examples of reduced instruction set computers include IBM, PC-RT, and Acorn Archimedes. The technology of these computers has been a major development in the field of microprocessors.

RJE

Abbreviation for remote job entry.

robotics
robotique f

Robotics. Electronics and microelectronics can be connected to machines, including cameras, to perform complex and repetitive tasks without human intervention. As machines become more "intelligent", more complex and complex tasks can be performed.
