Electronics is the discipline dealing with the development and application
of devices and systems involving the flow of electrons in a vacuum, in gaseous
media, and in semiconductors. 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.
History of electronic components
twentieth century. They took electronics from parlor tricks and gave us radio, television, phonographs, radar, long-distance telephony and much more.
They played a leading role in the field of microwave and high power transmission as well as television receivers until the middle of the 1980s.Since that time, solid-state devices have
all but completely taken over. Vacuum tubes are still used in some specialist applications such as high power RF amplifiers, cathode ray tubes, specialist audio equipment, guitar amplifiers and some microwave devices.
