Electronics is the field of Engineering and Applied fiziki.Rabota schemes depends on the flow of electrons for the generation, transmission, reception and storage of information. Today it is difficult to imagine our life without electronics. It surrounds us everywhere. Electronic devices are widely used in scientific research and industrial design, they control the work of factories and power plants, the calculation of the trajectories of spacecraft. Automation of production processes and the study of living organisms has been made possible thanks to electronics. The invention of vacuum tubes in the early 20th century was the starting point of the rapid growth of modern electronics. With the development of pipes, it has become possible to transmit information over the radio, creating kompyuterov.Tranzistor invented by American scientists WShockly, J.Bardeen WBrattain in 1948 and completely replaced the vacuum tube. With the invention of the transistor circuit all necessary functions can be performed within the solids. Early transistors may react at a rate of several million times per second. Instead, testing, assembly of discrete elements on the chip have been made larger grouping these components together with their interconnections all at once. 1C is significantly reduced device size, reduced costs and at the same time, they provide high speed and high reliability.
