Every electronics engineering should know basic functions of Electronic Devices.

Electronic devices perform three main functions:
(1) amplification,
(2) switching, and
(3) oscillation,
all as part of circuits. A circuit consists of a series of connected electron devices and other parts. By combining the three functions in various ways, engineers design electronic equipment that performs many other special functions, such as the high-speed operations of computers.
