Subject aims expressed by acquired skills and competences

Students will understand principles of computer networks mostly used today, gain ability to analyze network traffic, will understand most important protocols used in the Internet and will be able to design simple local area networks. They will also be able to orientate themself in options of LAN interconnections.

Teaching methods

Experimental work in labs
Project work


The course introduces basic principles and technologies of data networks. Students will understand basic data transmission principles, transmission media and methods of their sharing, basic protocols used to ensure reliable transmission, most frequently used network types and methods of networks interconnection. Introduction to protocols of most widely used Internet applications follows. Security issues of LANs and WANs are also discussed. In lab exercises students will learn how to design and implement simple secured network composed of basic active network devices and services.

Way of continuous check of knowledge in the course of semester

Tasks solved during exercises that verify students' ability to apply methods of computer network configuration in particular scenarios. Tests which verify students' ability to describe and explain individual technologies and principles of computer networks. Semestral project for group of students - network design and configuration. The aim is to demonstrate students' ability to utilize theoretical knowledge for synthesis of particular solution. Examination will be done in written form.
