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.

Operating Systems

Knowledge and understanding:
After completing the course students will acquire the basic concepts of how computer networks work and how they are structured.
Applying knowledge and understanding:
At the end of the course students will have acquired their own analysis and design methodologies of computer networks or their components
Making judgments:
At the end of the course students will be able to apply the methods of analysis and design of computer networks in order to solve problems and deploy digital devices in computer networks
Communication skills:
At the end of the course students will have acquired the ability to express the basic concepts of computer networks with appropriate terms and technical jargon.
Learning ability:
During the course the student will acquire the ability to study and learn the basics of computer and communications networks, through the assimilation of protocols and services.

Attendance

Course attendance is not mandatory but strongly recommended.

Course books

• Tanenbaum; Wetherall , "Reti di Calcolatori", from V Ed., Pearson, 2011
• J. F. Kurose - K.W. Ross, "Reti di calcolatori e internet Un approccio top-down "• 7/Ed. (Integrativo)
• Course Slides.

Others optional books or readings

• Forouzan, "Reti di Calcolatori e Internet", McGraw-Hill, 2010
• Stallings, "Sicurezza delle Reti - Applicazioni e Standard", Pearson, 2010
• 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: review questions on the syllabus and discussion on written part. 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.

Assessment

• First part: written test with problems, open and closed questions, paper on a topic. With this test we want to ascertain problem solving skills and abilities on real and complex topics in the field of networks; passing the test gives the right to access the oral part. The test is considered passed if the minimum required score is achieved (18/30).
• Second part: review questions on the syllabus and discussion on written part. 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
