Course abstract

Students learn the hardware types and principles of operation of the computer, as well as the operation and structure of individual electronic elements of the computer. Students acquire theoretical knowledge of the main components of a computer and computer peripherals (peripherals). Students gain insight into operating systems, working with Windows OS, installing new programs, and connecting external devices.

Learning outcomes and their assessment

As a result of mastering the study course, students:
• know the technical structure of the computer, computer elements, their structure, as well as the principles of operation of external equipment (defence of laboratory works);
• have skills to repair and upgrade computer and peripheral equipment, connect and customize additional external equipment, install and configure computer software (laboratory works);
• are able to choose the programs and components offered on the market corresponding to a certain task, to justify the purchase of computers for personal and commercial needs, to justify the purchase of computer peripherals, to justify the replacement of computer elements (laboratory works and their defence).
