Course content

Multimedia components and network based services, switching principles, network types, Internet. Reference models (i.e. OSI and TCP/IP) and generic protocol functionality. Functionality in the application layer, transport layer, network layer, link layer and (partly) physical layer. Within the application layer, architecture and protocols for the Domain Name System, e-mail and World Wide Web (WWW) will be focused. Introduction to multimedia systems. Introduction to wireless and mobile networks. Fundamentals of communication security.

Learning outcome

A. Knowledge: 1) A foundational understanding of the most fundamental concepts, principles and technologies underlying computer communication networks and services, including the overall architecture of the Internet, principles of network based services, principles of switching techniques, functionality and basic protocols of the five layers, and use of Transport Layer protocols in network application design. 2) A basic understanding of wireless and mobile networks. 3) A basic understanding of multimedia networking. 4) A basic understanding of 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 and why 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 contributes to almost all UN sustainable development goals (since efficient communication/networking is a fundamental need for all non-local cooperation) but maybe in particular:

• 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").
