Electrical engineering is the core and key subject in modern science and technology. Traditionally, electrical engineering has been defined as the sum of related disciplines used to create and produce electrical and electronic systems. This definition was originally very broad, but with the rapid development of science and technology, the concept of electrical engineering has gone far beyond the above definition. Professor Stanford University pointed out: "Today's electrical engineering covers almost all engineering behaviors related to electrons and photons".
It is the great progress of electronic technology that has promoted the arrival of the information age based on computer network and changed all aspects including human life and work style. Electrical engineering disciplines in American universities, also known as electrical engineering departments, electrical engineering and information science departments, electrical engineering and computer science departments, mainly focus on computers and information technology.
