Learning Objectives
The course introduces concepts related to computer networks, and the way to apply them to implement data networks, as LAN and WAN. At the end of the course students will be able to analyze and design the most common types of computer and digital devices networks, facing to theoretical and practical concepts that unify different telecommunications networks

Supporting Activities
- Lecture slides
- Web resources
Teaching, Attendance, Course Books and Assessment
- Teaching
Lectures and laboratory sessions for practical concepts
- Attendance
Attendance is not mandatory but highly recommended.
- Course books
- Tanenbaum; Wetherall , "Reti di Calcolatori", V Ed., Pearson, 2011
- Forouzan, "Reti di Calcolatori e Internet", McGraw-Hill, 2010
- Stallings, "Sicurezza delle Reti - Applicazioni e Standard", Pearson, 2010
- Further readings on Blended
- Assessment
- First part: Programming and report concerning networks, agreed with Professor, to be delivered a week before the exam date (Guidelines for the Exam's Report). With this test we want to assess skills and problem solving skills on real and complex topics in the field of networks. The test, if passed, gives access to the second part of exam.
- Second part: Discussion of the project and review questions on the syllabus. It aims to ascertain knowledge of the topics, general and particular, addressed during the course and to evaluate the deduction skills necessary to approach new problems in the context of computer networks
- Disabilità e DSA
Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.
A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
