Digital Evolution

With the evolution of Technology to which Electronics Engineering has played a very significant role, it has become possible for any individual from one corner of the planet to talk to another individual at other corner in just a fraction of a second.

Word Electronics comes from Electron which was first discovered by Sir J. J. Thomson in 1897. So, that clearly means we did not know the basic principles related to Electronics before 1897.

But once this concept was unveiled, there had been no looking back. During times of First and Second World Wars technology took quite an advanced shape. During those days technology components were mainly taken care of by concepts of Vacuum Tubes like Diodes (not semiconductor diodes), Triodes, Tetrodes and Pentodes. These electronic components were not only bulky but also very slow in operation.

A major milestone in this direction was achieved when a team of scientists comprising of Shockley, Bardeen and Walter conceptualized the prototype of a component called 'Transistor' in 1947 (year of Independence for India!). This single electronic component revolutionized the whole electronic industry and we started having different stages of Integrated Circuits(ICs) from 1958 onwards.
