Computing concepts

This course gives participants without a specific background a general overview of the basic principles and techniques of the IT world.

At the end of this course the participant will:

  • be familiar with the basic architectures and technologies of hardware, networks, communication;
  • be familiar with the functions and the types of operating systems;
  • understand the different kinds of applications: how they work and how they are made;


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.

Intended for

Future programmers or analysts without a specific IT background.


No specific previous knowledge is required.
