Learning activities and teaching methods
Monologic (reading, lecture, briefing), Skills training, Laboratory work, Stimulating activities (simulation, games, drama)
Learning outcomes
The course introduces fundamental concepts of the computer communication networks and their protocols, laying the foundation for advanced courses (Computer Networks II-IV). An emphasis will be placed on the layered network architectures, TCP/IP protocols and Ethernet technology. Students have an opportunity to gain the essential skills in the CNA (Cisco Networking Academy) lab. To continue in Computer Networks II-IV students should complete the CCNA class.
The CCNA1 course completion is a prerequisite for continuing to the follow-up courses Počítačové sítě II to IV (Computer Networks II to IV). Graduate Course Series Computer Networks I to IV acquires internationally recognized certificates of completion of Cisco Networking Academy.
Completion of the PUVPE course.

Assessment methods and criteria
Oral examination, Didactic test, Systematic monitoring

By awarding course credit it is confirmed that the student has fulfilled the required attendance and other qualifying conditions. Conditions for obtaining the credits are: active work at labs, min. 80% of presence, passing the CNA (Cisco Networking Academy) CCNA1 course. Form, contents and length of the exam are determined in accordance with the Study and Examination Regulations of University of Pardubice. The exam consists of two parts, a written test and an oral exam. Student passes the exam if he/she obtains at the minimum 50% of possible points in each part.
