Subject specific learning outcomes and competences

A student is able to configure network connection to the internet, configure basic services, monitor network traffic, detect and correct network failures.  He or she is familiar with modern network applications for data, voice and video transmission. A student has an overview of tools for network administration and is able to use them. He or she is capable to create a secure network connection over the internet and secure computer against misuse from the network. A student is able to program a network application.

Learning objectives

The goal of this course is to inform students about network services and tools for network administration and traffic control. The practical parts of the course include network application programming and laboratory assignments where students can apply theoretical knowledge in configuration and analysis of real network services.

Why is the course taught

The students will learn principles of basic network services, how to monitore and secure network devices and applications. In addition, students will be introduced BSD socket library for programming client-server applications.
