Answer 1

Answer:

Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter.[1] This distinguishes it from classical electrical engineering as it uses active devices to control electron flow by amplification and rectification rather than just using passive effects such as resistance, capacitance and inductance. 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.[2]This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950, this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes.

The term "solid-state electronics" emerged after the first working transistor was invented by William Shockley, Walter Houser Brattainand John Bardeen at Bell Labs in 1947. The MOSFET (MOS transistor) was later invented by Mohamed Atalla and Dawon Kahng at Bell Labs in 1959. The MOSFET was the first truly compact transistor that could be miniaturised and mass-produced for a wide range of uses, revolutionizing the electronics industry, and playing a central role in the microelectronicsrevolution and Digital Revolution. The MOSFET has since become the basic element in most modern electronic equipment, and is the most widely used electronic device in the world.

Answer 2

Explanation:

In these past few years, digital technology has become a vital factor in accelerating the pace of India’s economic growth, in promoting social and economic equity by enhancing access for all to information, markets and public services; and in overcoming the country’s infrastructure deficit. Digital technology can help India realise the ambition of creating a just and equitable society. It can help propel India to the front rank of nations, particularly leveraging the energies of the country’s youthful population, with its propensity for quick adaptation and frugal innovation. 

The ‘Digital India’ initiative was launched by Prime Minister Narendra Modi on 1 July 2015, and on the fourth anniversary of the programme, we can celebrate the fact that there have been dramatic improvements in all of its three key facets: in the creation of pervasive national digital infrastructure, in the electronic delivery of public services and financial succour to citizens, and in enhancing digital awareness and literacy.
