Learning activities and teaching methods
Monologic (reading, lecture, briefing), Demonstration
  • Class attendance - 25 hours per semester
  • Preparation for credit - 50 hours per semester
  • Preparation for exam - 25 hours per semester
Learning outcomes
The goal of the course is to provide a comprehensive overview of the TCP/IP family of protocols and how LANs and WANs work today.
Students should be able to practically design simple local area networks, be familiar with network administration and networking options for local area networks (including Internet connectivity) and basic computer network security issues.
Prerequisites
Basic knowledge of operating systems.

Assessment methods and criteria
Combined exam

Completion of assigned tasks from the exercises, writing a credit thesis in the form of a written test with a score determined by the professor at the beginning of the semester with the possibility of one correction (one remedial attempt possible). At the regular and correction credit term, as well as at each examination terms, all aids are prohibited except those permitted by the teacher.
