A cyborg is a crossing between human beings and computer-guided machines.
Cyborgs are partly creatures from social reality, and partly fictive beings.
In science fiction, cyborgs are often represented as creatures who look like people, behave like people and act like people, but contrary to human beings, they have computers and electronics under their skins. Cyborgs however, do not only exist in science fiction books or -movies. Cyborgs can also be found in modern society. A cyber-punk is a 'computernetworkfreak'. The term is also used for a movement in science fiction concerning computernetworks.
