Annotation

The main goal of the course is to provide students with basic knowledge of information transmission through communication environment, coding and signaling. Students receive basic knowledge about current standards and modern terminology related to computer communications. In the context of local networks, methods of coding information, modern modulation schemes, physical interfaces are considered. Initial knowledge is given about the types of physical and logical topologies of computer networks and about the functioning of the devices necessary for their construction. Students get acquainted with different transmission environments and protocols working on the physical and channel layer of the OSI model.
