These layers include information, computer hardware, low and high level programming languages, problem solving and algorithms, abstract data, computer operating systems, applications, computer communications through networks and the Internet.
An electrical engineer is someone who designs and develops new electrical systems, solves problems and tests equipment. They study and apply the physics and mathematics of electricity, electromagnetism and electronics to both large and small scale systems to process information and transmit energy.
Electronics engineers analyze the requirements and costs of electrical systems. Electrical engineers design, develop, test, and supervise the manufacturing of electrical equipment, such as electric motors, radar and navigation systems, communications systems, or power generation equipment.
