ELECTRONICS is the field of science and engineering that deals with devices in which conduction is principally by electrons moving through a vacuum, gas, or semiconductor and with utilization of these devices. (Roy A. Colclaser)
ELECTRONICS is the science and technology of the passage of charge particles in gas, in a vacuum, or in a semiconductor. The particle motion confined within a metal only is not considered in electronics. (Jacob Millman)
ELECTRICAL ENGINEERING is the field which deals with devices that depend solely on motion of electrons in metal, for example a generator, a motor, a light bulb, or telephone. The principal benefactor of these devices are telephone or telegraph companies, and the power industries. (Jacob Millman)
