Electronics is the branch of
science and
technology which makes use of the controlled motion of
electrons through different media and vacuum. The ability to control electron flow is usually applied to information handling or device control. Electronics is distinct from
electrical science and technology, which deals with the generation, distribution, control and application of electrical power. This distinction started around 1906 with the invention by
Lee De Forest of the
triode, which made electrical
amplification 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.
Most electronic devices today use
semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of
physics, whereas the design and construction of
electronic circuits to solve practical problems come under
electronics engineering. This article focuses on
engineering aspects of electronics.
