Summary
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.
