Electronics deals with [[electrical circuit]]s that involve active electrical components such as [[vacuum tube]]s, [[transistor]]s, [[diode]]s, [[sensor]]s and [[integrated circuit]]s, and associated passive interconnection technologies.<ref name="HH2015">{{cite book|title=The Art of Electronics |edition=3rd |first1=Paul |last1=Horowitz |first2=Winfield |last2=Hill |publisher=Cambridge University Press |year=2015 |isbn=978-0-521-80926-9}}</ref>{{rp|1–5,71}} The [[Nonlinear element|nonlinear]] behaviour of active components and their ability to control electron flows makes digital [[switch]]ing possible,<ref name="HH2015"/>{{rp|75}} and electronics is widely used in [[Data processing|information processing]], [[telecommunications]], and [[signal processing]]. Interconnection technologies such as [[circuit board]]s, electronics packaging technology, and other varied forms of communication infrastructure complete circuit functionality and transform the mixed components into a regular working [[system]].<ref name="HH2015"/>

Today, most electronic devices use [[semiconductor]] components to perform electron control. The underlying principles that explain how semiconductors work are studied in [[solid state physics]],<ref>{{Cite book |last=Singleton |first=John |url=https://books.google.com/books?id=9SLSBAAAQBAJ |title=Band Theory and Electronic Properties of Solids |date=2001-08-30 |publisher=Oxford University Press |isbn=978-0-19-105746-5 |pages=49 |language=en}}</ref> whereas the design and construction of [[electronic circuit]]s to solve practical problems are part of [[electronics engineering]].<ref>{{Cite book |last1=Agarwal |first1=Anant |url=https://books.google.com/books?id=lGgP7FDEv3AC |title=Foundations of Analog and Digital Electronic Circuits |last2=Lang |first2=Jeffrey |date=2005-07-01 |publisher=Elsevier |isbn=978-0-08-050681-4 |language=en}}</ref>
