Annotation

The main objective of the course is to provide the students with basic knowledge about the purpose and operation of network devices, configuration of end devices and network devices. The students receive a basic knowledge of computer network performance, they differentiate a different types of network devices, and know how to develop network solutions. The course makes the students familiar with current standards and modern terminology related to computer networks. In the context of local and Internet networks, security, performance, reliability and fault-tolerance are considered. They are familiar with the main diagnostic tools for monitoring and troubleshooting networking issues. Initial knowledge for building a physical topology and skills for designing logical topology of computer networks is given.
