Training objectives
- Knowledge on the working principles of telecommunications Networks in use, with brief historical remarks to understand the evolution but also the principles that remain stationary in the course of evolution. Special emphasis is ginver to the physical and datalink layers while application layer is briefly mentioned as it is well covered in other courses. At the end of course the student should be able to understand how the various networks on which he operates (ethernet, wireless, cellular data network, fiber optices, ipv4, ipv6) and understand the services they offer, but also the limits (in term of bandwidth, latency, error rate, for example). He should also be able to undestand the origin of any malfunction or the origin of performances below expectations.
Prerequisites
- Basic knowledge of computer science. The student must be able to make conversion between binary, decimal and hexadecimail numbers.
Basic knowledge of mathematics. The studend must know how to make operations with scientific notation.
Basic knowledge of physics. Speed of Light, Use of simple direct and inverse formulas of physical quantities related to computer networks. Course programme

Didactic methods
- Lectures with aid of projected slides. The course is mainly on slides but also on small education programs and example of analysis of packet sniffers. Example of diagnostic programs on personal computers. During the course there are also two self assessment tests.
Learning assessment procedures
- Oral Examination on all the topics covered during the lectures. Examination aims to assess the student knowledge, mainly on base concept and expertise acquired more than on notionistics informations.
Reference texts
- Slides with pictures from Tanenbaum's and other books. The slides contain all the topic discussed during the lectures. However some topics of the slides are not discussed in the courses and are left on the slides as reference.
Reference Book
"Computer Networks" (A.S. Tanenbaum) Pearson
