Electronics

Introduction:

Electronics is the application of devices controlling the flow of electrons. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible. Electronics is widely used in information processing, telecommunication, and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Interconnection technologies such as circuit boards electronics packaging technology and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working.
