CONTENUTI

This course introduces the fundamental concepts of modern computer networks, in order to provide students with the knowledge needed for the analysis and design of a computer network. We will discuss the general characteristics of the networks, the ISO/OSI and TCP/IP models, and the problems to be solved at each level of these models. For each level, besides general discussions of the problems, we will present the main solutions used in practice. We address also the security issues of communications between computers; for this purpose, we will introduce some notions about cryptography.
