60 exam, 18 half-term test, 22 projects




Subject specific learning outcomes and competences

Students are able to configurate network connection to internet, configure basic services, control network traffic, detect and correct network failures. They are capable implement a new network application. They are familiar with modern network application for data, voice and video transmission. They know tools for network administration and are able to use them. They are capable to create a secure network connection over internet and secure computer against misuse from network.

Learning objectives

The goal of this course is to inform students about network services and tools for  network administration and traffic control. Practical part of the course includes TCP/IP network programming using BSD sockets and laboratory assignments.
