Course content

The course focuses on computer networking, involving many concepts, protocols and technologies that are woven together in an intricate manner. The broad spectrum of topics is presented following the top-down approach, i.e. by beginning with the application layer and working its way down toward the physical layer. The covered topics include reference models (i.e. OSI and TCP/IP), switching and routing principles, network elements, services and protocols widely used in the Internet. Within the application layer, the architecture and protocols for the Domain Name System (DNS), web and e-mail are discussed. An introduction to multimedia systems, wireless and mobile networks, and fundamentals of communication security is also given.

Learning outcome

A. Knowledge: Students will get a basic understanding of: 1) The fundamental concepts, protocols and technologies underlying computer communication networks and services, including the overall architecture of the Internet, principles of network based services, switching and routing techniques, functionality and basic protocols of the five layers, and use of transport layer protocols in network application design. 2) Wireless and mobile networks. 3) Multimedia networking. 4) Communication security.

B. Skills: 1) To be able to communicate, reason and creatively think about the architectures, principles and technologies in the design and implementation of computer communication networks and services. 2) To be able to explain how the basic protocols of the five layers work. 3) To be able to communicate, reason and creatively think about wireless and mobile networks, and multimedia networking. 4) To be able to design and implement basic network applications using the existing transport layer protocols. 5) To be able to provide fundamental security in communication over networks.

The course teaches the fundamental knowledge, skills and competences behind digital communications and the Internet. For that reason, it indirectly contributes to all UN Sustainable Development Goals (SDGs) where digital solutions can benefit from ubiquitous access to a communication platform and, in particular, to:

• Goal 4 "Ensure inclusive and equitable quality education and promote lifelong learning for all" ("Infrastructure solutions that bring Internet access; downloadable digital content; digital platforms and remote learning programs").
• Goal 9 "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation" ("Industrial Internet of things (IIoT); 5G network connectivity to enable industrial automation and the associated efficiency gains; Cross-team collaboration opportunities enabled by digital platforms").
