Electronics is the science and technology of electronic circuits[?] and devices such as thermionic valves and semiconductors using the physics of electricity. This knowledge is applied in devices that manipulate electric currents and electromagnetic fields for the controlling or processing of information, or the conversion and distribution of electrical power. While electricity had been used for some time to transmit data over telegraphs and telephones, the development of electronics truly began in earnest with the advent of radio. Today, electronic devices perform a variety of tasks.
An electronic system can be divided into the following parts:
Take as an example a television. Its input is a broadcast signal received by an antenna or fed in through a cable. Signal processing circuits inside the television extract the brightness, colour and sound information from this signal. The output device is a cathode ray tube that converts electronic signals into a visible image on a screen.
