Electronics is the study of electricity (the flow of electrons) and how to use that to build things like computers. It uses circuits that are made with parts called components and connecting wires to do useful things. The science behind Electronics comes from the study of physics and gets applied in real-life ways through the field of electrical engineering.
Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter. It uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering which uses passive effects such as resistance, capacitance and inductance to control current flow.
Electronics has had a major effect on the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small electrical signals, inaugurated the field of electronics and the electron age.
Electronics’ actual history began with the invention of vacuum diode by J.A. Fleming, in 1897; and, after that, a vacuum triode was implemented by Lee De Forest to amplify electrical signals. This led to the introduction of tetrode and pentode tubes that dominated the world until World War II.
This is all about the fundamental understanding of electronics history. This history of electronics technology costs a greater investment of time, efforts, and talent from the real heroes, some of them are described below.

IC (Integrated Circuit) – Jack Kilby invented this. A precursor concept to the integrated circuit was proposed by Kilby to the US Army in 1957. But soon as that project of his started gaining momentum, he came up with the revolutionary design of an integrated circuit.
Functions of the Electronic
Electronic devices tend to perform the following main functions:
Rectification
The process of converting an alternating current (A.C.) to a direct current (D.C.) is known as rectification. Electronic devices can convert A.C. power into D.C. power which has various uses like charging storage batteries, electroplating, etc., with great ease as well as efficiency.
Amplification
A weak signal can be strengthened through the process of amplification and this process can be very easily achieved by electronic devices. A good example would be the usage of an amplifier in a radio set so that it is heard more loudly.
Generation
Electronic devices are also capable of converting A.C. power into D.C. power of any given frequency. And when these devices perform this particular function, they are commonly referred to as oscillators.
