Themen der Lehrveranstaltung
This course aims at providing a solid background in computer networks. Theory will be intertwined with discussions about how the notions introduced are exploited in practice, taking the Java framework as reference. This will allow to see in real contexts why distributed systems are important.

Unterrichtsform
The course includes frontal lectures and lab exercises.

Bildungsziele
Knowledge and Understanding – D1.11 Know in detail the principles of computer networks and distributed systems – D1.12 Know in detail the internet fundamental principles and the methodologies for their design and development.

Learning skills – D5.1 Have developed learning capabilities to pursue further studies with a high degree of autonomy. – D5.3 Be able to follow the fast technological evolution and to learn cutting edge IT technologies and innovative aspects of last generation information systems.

Art der Prüfung
The assessment consists of an oral exam (D1.11, D1.12, D4.1, D5.1, D5.3) and lab reports, which contain practical excercises (D1.11, D1.12, D2.9, D4.1, D4.2) and project work (D2.9, D3.1, D3.2, D4.2, D5.1).

Bewertungskriterien
Marks are distributed as follows: 30% for the lab reports and 70% for the oral exam. Attending the lab is not mandatory but is recommended, as it can help improve the oral exam grade. The final grade is calculated as a weighted average of the lab reports (30%) and the oral exam (70%). However, the lab report marks are considered only if they are higher than the oral exam grade. The 30% weight for the lab reports applies only if three assignments are submitted; if fewer assignments are delivered, the weight is adjusted proportionally.
