The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the field of electronics engineering, and includes the hardware design side of computer engineering.

The study of new semiconductor devices and their technology is sometimes considered as a branch of physics. This page focuses on engineering aspects of electronics.
