Also referred to as Electronics engineering, it uses the scientific knowledge of the behaviour and effects of electrons to develop components, devices, systems, or equipment (as in electron tubes, transistors, integrated circuits, and printed circuit boards) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many sub-fields including those that deal with power, instrumentation engineering, telecommunications, semiconductor circuit design, and many others. This field has important opportunities related to consumer electronics including computing hardware. The revolution in hardware for computers and peripherals coupled with explosion of embedded electronics in all day-to-day products, the demand for electronic engineers is only going to rise rapidly. Areas such as power electronics and digital electronics are going to experience fast paced growth creating large number of career opportunities.
