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.

Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Teaching, Attendance, Course Books and Assessment

Teaching

In-person lectures and laboratory sessions for practical concepts

Attendance

Attendance is not mandatory but highly recommended.

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
Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
