What is an explanation of the term cybernetics?

Cybernetics comes from the Greek word Kybernetes, which means helmsman, and is the science involving communication and control between organic and mechanical systems.

A modern-day example of this science is cutting-edge prosthetics, which operate based on the neurological commands of the patient. Recently, advances have been made in games which can be played using your own neurological input, which is another form of cybernetics.

In popular fiction and movies, cybernetics usually involves enhanced devices and artificial limbs grafted to a person, or a person's brain transplanted into a machine. Examples of these are Robocop, Cyborg and the pen-and-paper roleplaying games Shadowrun and Cyberpunk. Cyberpunk is also the name of the writing genre involving cybernetic technology, started by the author William Gibson.
