Introduction :

IT - Information and automatic contraction - is the domain of scientific activity, technical and industrial related to the automatic processing of information by machines such as computers, game consoles, robots, etc..

The term "computer" refers to the original theoretical computer science: a set of formal sciences whose aim is to study the concept of information and methods for automated processing thereof. These include, for example, algorithms, signal processing, computability and information theory.

The automation of information processing is much older than the invention of the computer. The first automated processing machines were mechanical machines built in the seventeenth century.

"Computer science is not science more about computers than astronomy is one of the telescopes [1]"
- Edsger Dijkstra

Appeared in the 1950s, the industry of information technology and communication is linked to the computer, electronics and telecommunication. The activities are the production of computer hardware - machinery and parts, and software - treatment processes - which are intended for the acquisition, storage, processing, transmission and retrieval of information automatically. The sector also provides many services related to the use of its products: education, support, monitoring and maintenance.
