A different example is the use of antennas and transmitters for the coverage of a cellular phone network. Yet another application is in the communication systems of the Information Highway. Networks and Systems is the study and design of electrical circuits. Circuits are designed to perform specific functions. It could be a decoding circuit in a CD player or an ethernet card for a computer.
Power involves the generation and transmission of electrical energy.
Computer Engineering deals with all aspects of the computer. This includes everything from the digital systems inside the computer, to programming in both high and low level programming languages. Electronic Devices and Circuits is the study of semi-conductors and electronic circuits. This area is involved with the design of integrated circuits which are used in computers and most electronic devices produced today. The field of electrical engineering is one that is continually expanding.
