English from the computer, "computer" in French means "computer".
The function of computing a computer does not limit the use of the calculator,
a spreadsheet or execution of programs of scientific calculations.
There are in fact the calculation in all operations that performs a computer:
- Viewing a web page or document created with a word processor,
- The encoding and decoding of information stored in files,
- Management of communications with other computers on a network ..
For example, when one writes a letter in a word processor, it must
be able to transform all of its content (here the text and its implementation
form) in a series of numbers that the computer can then store or handle.
This operation, called "coding information," is one of many
arithmetic operations needed to run different programs
