Course Description:
The course covers the basics of computer networks with emphasis on the Internet. Students are introduced to networks\' architectural and functional principles, essential terminology, working methods and layered approach of the reference models. They get to know the operating model of the TCP/IP protocol stack, the architecture of the Internet, its hierarchical addressing system, the functioning of protocols ensuring basic Internet services. Other areas of coverage include the main functioning methods of computer networks, their opportunities for use, performance characteristics and specifics of application. Students also familiarize themselves with the physical data transfer environment of computer networks, the methods and haracteristics of their use and some details of operation.
Network reference models, Internet basics, Internet’s hierarchical addressing method, domain name system (DNS), IP protocol, basic ideas of packet switching and routing, concepts of onnectionless and connection full data transfer, transport protocols and their performance, wired and wireless local area networks, basics of Ethernet.

Assessment: Two tests during the semester on the lab practices. Both tests have be written and at least 50% has to be achieved. At least one has to be above 50% for the student to qualify for a replacement test. Lab practice tests yield the signature. Apart from the tests each student must hold a presentation on a networking topic. The details, topics and schedules will be presented at the first lecture.

Exam Types:

Test Exam
