Question

A short paragraph on 'An Electronic Device'( in 75 words )

Answer 1

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components (such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics, and sensors), associated passive electrical components, and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

The science of electronics is considered to be a branch of physics and electrical engineering.[1][2]

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 system.

Answer 2

Looking back at the time when there were no mobiles, television or refrigerators, life is impossible to think of. There was no source of communication, it was difficult to travel from one country to another. Now that technology has become advanced life has become more comfortable and easier.

There are many electronic devices such as refrigerators, television, mobile, computers and so forth. Each electronic device has its own benefits and uses. One can connect in any corner of the world in just a click of a button. Foods can be kept fresh for a longer time with the help of refrigerators and prevent wastage of foods. Television helps in connecting us with the corer of the worlds and provides entertainment.

Hadn't been it technology the life would be difficult. Therefore, electronic devices must be used wisely.
