Electrical engineering

Electrical engineering comprises the study and application of electricity, electronics, and electromagnetism.

Subdiscipline	Scope	Major specialties
Computer engineering	The design and control of computing devices with the application of electrical systems.	Software engineering: the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering andcomputer science to software. Hardware engineering: designing, developing, and testing various computer equipment. Can range from circuit boards and microprocessors to routers. Network engineering: designing, deploying and maintaining computer networks, such as corporate networks or the Internet.
Electronic engineering	The design of circuits that use the electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality.	Control engineering, focuses on the modeling of dynamic systems and the design of controllers using electrical circuits, digital signal processors and microcontrollers Telecommunications engineering
Optical engineering	The design of instruments and systems that utilize the properties of electromagnetic radiation.
Power engineering	The generation, transmission and distribution of electricity, and the design of devices such as transformers, electric generators, electric motors, high-voltage engineering, and power electronics.
