Characterizing
Prerequisites. It is needed to have passed Operating Sytems. It is recommended to have passed the exams of Analysis, Calculus of probability and statistics.
Teaching Methods. Class lectures with examples and exercises, also about the written exams.
Verification of Learning. The exam consists of a written test and possibly an oral examination to discriminate the “border cases”. The written test consists in exercises and theoretical questions concerning the topics of the course. The site elearning.uniud.it provides old exams, with solutions. The oral test consists of 2-3 questions.

Contents
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.
