Computer Peripherals

Weekly classes 2+0+2
Control form Exam


The subject is intended to give some theoretical knowledge about the application of the computer peripheral and the ways and means of its management. It has to form practical habits in the students for its use. For this purpose, the principles, technologies and means of storing, entering and outputting information in computer systems are discussed. Ways to test the performance and device parameters are considered. The main representatives of a class of peripheral devices and the standard interfaces for connecting them to computer systems are studied. The basic software features are considered to ensure the proper functioning of peripheral devices in the computer configuration.
