What is cybernetics?

The word “Cybernetics” was first defined by Norbert Wiener, in his book from 1948 of that title, as the study of control and communication in the animal and the machine. The term cybernetics stems from the Greek κυβερνήτης (kybernētēs, steersman, governor, pilot, or rudder — the same root as government).

Thanks to the movie industry, machines based on cybernetics, robotics and biology have been quite popular. Such a machine is commonly known as a cyborg, which is an organism that has both artificial and natural systems. This type of organism can be seen as a self-regulating human-machine that make use of sensor, artificial intelligence and feedback control systems. In addition to this, cyberspace (electronic medium of computer networks in which online communication takes place) is closely related to cybernetic signal processing and communication theory.
