The ability to control the flow of electrons is usually applied to the manipulation of information or control device. The electronics are electrically non-technology and science that deals with the production, distribution, control and use of electricity. This distinction started around 1906 with the invention by Lee De Forest triode, which is the final stage of a non-mechanical device. This field is called "wireless technology" because its main application is the design and the theory of radio transmitters, receivers and tubes to 1950.
Semiconductor devices in most electronic devices for the control of electrons used in the present. The study of semiconductor devices and related technology is considered a branch of physics, while solving the design and construction of electronic circuits practical problems associated with the electronics. The article focuses on the technical aspects of electronics.
Electronics is a physical unit in the electronic systems used to affect the electrons or related fields in the desired manner in accordance with the intended use of the electronic system. Components are usually connected to, usually by pointing to a printed circuit board (PCB) soldered to create an electronic circuit with a specific function (eg, an amplifier, radio receiver, or oscillator). Components can be packaged individually or in groups as complex integrated circuits. Some common electronic components, inductors, resistors, diodes, capacitors, transistors, and so on. The components are often classified as assets or liabilities.
