Course detail

Communication Technology

FEKT-BKC-KOMAcad. year: 2023/2024

The course is focused on these topics: networks and protocols – communication models, methods of information transmission, reasons for the use of networks, basic structure of networks, types of networks, architecture of communication systems, ISO/OSI reference model, TCP/IP network model. Principles of communication techniques – multiple utilization of transmission channels, duplex communication. Analysis of tasks of every layer of communication models with respect to ISO/OSI and TCP/IP – physical layer, data-link layer, network layer, transport layer, session layer, presentation layer, and application layer.

Entry knowledge

Students who are going to attend this course should be able to:
- use several numerical systems and conversions among them,
- explain and use elementary units common in the area of information and communication technologies (ICT), e.g. data size,
- use elementary terms from the ICT area, e.g. operating system.
Work in the laboratory is conditional on a valid qualification of a student according to the Decree No. 50/1978 Coll. (Czech rule), which students must obtain before starting the course. Information on this qualification is given in the Dean's Directive on familiarisation of students with safety regulations.

Rules for evaluation and completion of the course

Up to 30 points for laboratories (points are earned for independent assignments, test and laboratory protocols). The credit is conditional upon the student's attendance, submission of all individual assignments and obtaining at least 15 points.
Up to 70 points are awarded for the written examination. In order to pass the course, it is necessary to obtain a total of at least 50 points (the sum of points from the labs and the exam).
Attendance at laboratory exercises is compulsory, properly justified absence can be made up after after prior arrangement with the instructor.


The goal of the course is to provide students with some orientation within the fundamental types and structures of communication networks designated for transmission of data and within the technologies of information transmission that are used in them.
Students who will complete this course will be able to:
- describe and explain the basic communication models and methods of information transmission,
- list the basic network structures and express their performance parameters,
- describe and explain the general architecture of communication systems,
- identify the differences between ISO/OSI and TCP/IP network models, define these models,
- describe the basic principles of multiple utilization of transmission channels and methods for providing two-way communication,
- explain the operation of the physical layer of transmission systems,
- explain the task of the data-link layer of transmission systems,
- express the fundamentals of operation and services of the network layer of transmission systems, including the role of main protocols,
- interpret the function of the transport layer of transmission systems,
- explain the role of the session and presentation layers of transmission systems,
- describe selected tasks and protocols of the application layer of transmission systems.
