The classic division of electrical engineering into high and low voltage engineering has been further subdivided over time.
Today we talk about energy, drive and telecommunications engineering.
In all branches of engineering the various physical quantities are measured and often regulated to specified values: pressure, temperature, flow rate, weight, speed, power, voltage, current, etc.
The definition of a technical process in accordance with DIN 6622 is as follows: A process is the forming and / or transport of matter, energy or information. The state variables of technical processes can be measured, controlled and / or regulated by technical means.
Information technology interweaves technical computer science, which, inter alia, deals in networks, structure, function and interfaces of computers and their organization; and theoretical computer science, which deals with the processing, transmission and reproduction of information by means of abstraction, modelling and structuring.
