electrostatic printer
imprinante f électrostatic

Electrostatic printer. This machine prints on paper by charging selected areas of it (such as rubbing a balloon on the sleeve of a jacket and sticking it to the ceiling), so that these areas can attract fine dust that melts with heat and sticks permanently to the paper.

emulator
émulateur m

Qualifier. A piece of hardware (and possibly software) that, when connected to a computer, makes it behave as if it were a different type of computer. Thus, with the help of a qualifier, programs intended for one series of computers can be executed on another series of them.

encoder
codeur m

Coder. A device (such as a touchpad or a position indicator on a switch handle) that converts signals into a coded digital form necessary for the next operation.

end mark
mark f de fin

End mark. When working with a stream of data it sometimes becomes necessary to indicate the ends of different materials, which is done using a specific code known as (end mark).

EPROM
memory that can be programmed and erased. Abbreviation for erasable prog rammable read only memory, a type of read-only memory chip that can store programs or data. The data can only be erased by exposing the chip to strong ultraviolet rays.

erasable storage
memory that can be erased

Erasable storage. A storage medium that can be used repeatedly by writing new data over the old one.

erase
effacement m

Erase. The removal of previously stored data. However, unlike the removal of a normal pen mark by scratching, which is completely erased, in computer science the word means the replacement of a code that does not represent any data with another code. The new code may be zeros, but this is not necessarily required. Every time data is stored, whether in the computer's memory or on a disk or tape, the new data replaces the previous data, or it erases what was originally stored.

error

Error f

Error. An error is said to occur when the expected results do not appear. Errors in a computer system can result from software errors, hardware malfunctions, or human errors:

1 - There are three types of software errors:

(a) Syntax errors: Errors in using programming rules such as PRIT instead of PRINT.

(b) Logical errors: Errors in the sequence of information, such as forgetting to GO TO to skip the next instruction.

IFA=B PRINT A is equal to B

Forgetting to GO TO to skip the next instruction
PRINT A is not equal to B

(c) Run/execution errors: These errors can only be found when the program is running, such as writing the forewords in the same color as the background of the screen.
Software bugs can be found using a trace program or a dry run on paper (especially in cases of syntactic and logical errors).

2 - Service engineers can find errors caused by hardware failures by running special diagnostic routines.

3 - Operator errors can result from using the program at the wrong time or out of sequence. They also include accidental loss or damage of backup storage.

error message
messge m d'erreurs

Error message. When an error occurs, the program can indicate what went wrong by displaying a message on the screen. This is known as an error message and helps the user find the fault quickly.

For example: The statement "Cannot divide by zero at line 230) is an error message that tells the operator that the denominator (output) value in instruction 230 of the program is zero.

exclusive - OR gate
circuit m OU exclusif

Gate or compartment. A logic gate that operates with binary numbers. Its output is logical 1 when any of its inputs has the logical value 1, and it does not have such a value if all of its inputs are 1.

Inslusive - or Its output is 1 if all of its inputs are (1).

For example: The following truth table applies to or the two-input gate.

This gate can be used to add two binary numbers, but it does not give the carry-over number.

execute

Execution. A word used to describe the execution of an entire program or just a single instruction.

exit
sortie f

Exit. The exit results from the last instruction in a routine that returns the computer to the main program, or it may be the end of the entire program.

extended BASIC
BASIC m étendu

Extended BASIC. BASIC is a computer programming language, and Extended BASIC is any version of this language that provides additional functions and facilities.
