Italian

The course will present the basic concepts of Computer Networks and the Internet. Using a top-down approach, the different network layers will be presented: Application, Transport, Network and Link. Wireless and mobile networks and basics of network security wwireless networks and mobile networks. Will be introduced to the main issues related to multimedia networks. Finally, we will study some of the basics of network security.

Computer Networking: A Top-Down Approach (6th edition)

Pearson 

The course aims at introducing students into the principles of Computer Networks. At the end of the course a student should be able to evaluate the underlying network infrastructure and the different available protocols to use to support developing of network applications. Different tools will be presented to the students for assessing the different possibile solutions according to the specific context where a network must operate.

Basic knowledge of operating systems and concurrent programming.
