Entry knowledge

Basic knowledge of mathematics (probability theory) and information theory (Shannon theorem, errors in the transmission, coding) is requested.

Rules for evaluation and completion of the course

Computer exercises (22 points), laboratory exercises (18 points), final exam (60 points).
Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually.

Aims

Lectures are focused on presenting structure, architecture, and operational principles of computer and communication networks to students, and on training practical approaches to their design and configuration.
The graduate is able to: (a) understand basic theoretical principles of computer networks; (b) describe functions of individual components and protocols; (c) utilize network communication in designed instruments; (d) design and configure local networks.
