Electronics differ from electrical science and technology the distinction started around 1906 ad until 1950 this field is called radio technology. Electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits.] Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information. Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Radio became more useful after the invention of electronic devices.

Passive components and active components are the two major components of electronics. Passive components are those that do not have gain or directionality. In the Electrical industry they are called Electrical elements or electrical components. Active components are those that have gain or directionality, in contrast to passive components, which have neither. They include semiconductor devices and vacuum tubes (valves). Components are intended to be connected together, usually by soldering to a printed circuit board.

Electronic waste is a growing problem worldwide. One problem that fuels the electronic waste boom is the constant release of new products into the consumer stream. Making it easy for people to replace their stuff. By reusing or recycling it helps to stop the hazardous materials such as lead, mercury, arsenic and many more to enter the environment which is very beneficial to the human health. If you're really done with that old electronic stuff consider donating it. As the world starts to embrace recycling and learns about the environmental costs of dumping electronic waste and haphazard recycling techniques, more companies are feeling pressure from individuals and organizations to make their operations more environmentally friendly
