Electrical engineering is the largest of the engineering fields and pertains to the research and development, design, and manufacture of systems and devices that use electric power and signals, electrical machinery, electronic circuits, control systems, computers, superconductors, robotics, lasers, radar, consumer electronics, and fibre optics.
Electronic engineering is associated with the transmission and processing of information by way of research, design, and application of circuits and devices. Computer engineering is now the most rapidly growing field, and deals with the design and manufacture of memory systems, central processing units, and of peripheral devices.
These circuits are designed to perform specific tasks, such as reading radio signals to recover the information they carry, amplifying electronic signals, and adding binary numbers. Electronic circuits are also used to generate waveforms (as seen on a simple oscilloscope) which can then be used for timing and synchronization, as found in television broadcasting, and for correcting errors in digital information, as in telecommunications.
Mechanical engineering
The mechanical engineer has a broad learning curve consisting of mechanics, hydraulics, and thermodynamics and must have a basic grounding and be knowledgeable in metallurgy and machine design. They design, build, test, and operate all types of machinery. Mechanical engineers are adept with materials, hydraulics, and pneumatics, and the field also covers work and energy (enthalpy), heating, ventilating, and air conditioning.
Chemical Engineering
Chemical engineering is concerned with the processes of chemical reactions with certain materials, whereby chemicals are mixed with the pulverized material in question and tested for their reaction.
