The word 'electronics' is derived from 'electron' which is present in every material. The behaviour of an electron under condition of externally applied fields is studied under electron mechanics.
Electronics is the branch of science and engineering which deals with the flow of electron through vacuum, gas or semiconductor.

Electronic Components
Electronics components are the basic physical quantity in an electronic system, used to affect electron and by these electronic components complex circuits can be designed easily on a PCB board.
It is a device which strengthens weak AC signals. The process of strengthening the weak signals is know as amplification.
