Electronics is a science about the devices and processes that use electromagnetic energy conversion to transfer, process, and store energy, signals and data in energy, control, and computer systems. This science plays an important role in the world progress. Implementation of electronic devices in various spheres of human activity largely contributes to the successful development of complex scientific and technical problems, productivity increase of physical and mental labour, and production improvement in various forms of communications, automation, television, radiolocation, computer engineering, control systems, instrument engineering, as well as lighting equipment, wireless technology, and others. Contemporary electronics is under intense development,.
