Cyber-, from "cybernetic", from the Greek for "skilled in steering or governing"

Cyber- is derived from "cybernetic", which comes from the Greek word κυβερνητικός meaning skilled in steering or governing. It is mainly used in the terms cyberspace, cyberlaw, cyberbullying, cybercrime, cyberwarfare, cyberterrorism, cybersex, and cyberdelic among others. Although it is more commonly used to describe policies and politics regarding computer systems and networks (as in the above cases), it is also widely used by many information technology industries. Cyber is now considered as a recent term in the internet era.[1]
