65 exam, 18 mid-term test, 17 projects




Subject specific learning outcomes and competences

Students are able to configurate network connection. They have an overview of basic network services adn are able to administrate DNS, DHCP, mail services etc. They can program network applications using BSD sockets. They can read standards and use them to program application. They know standard tools for network administration and are able to use them.

Learning objectives

The goal of this course is to inform about network services and relevant protocols and to learn students how to administrate  network applications and computer networks. Practical part of the course deals with TCP/IP network programming using BSD sockets and laboratory assignments.
