This section gathers a series of open questions that have been designed to enable the students to improve their understanding of the topics presented in the e-book. These open questions typically contain a small problem that needs to be solved by the student. They are designed so that they can lead to discussions with teaching assistants.

Several Multiple Choice Questions and simple exercises are included in the main text and supported by the https://inginious.org platform.

A good understanding of the topics covered by this e-book can only be obtained by solving the proposed exercises. Reading the e-book from the first to the last page is not sufficient to get a detailed knowledge of computer networking.
