Cyberspace

Cyberspace (from Greek Κυβερνήτης [kybernētēs] meaning "steersman", "governor", "pilot", or "rudder") is the global domain of electromagnetics as accessed and exploited through electronic technology and the modulation of electromagnetic energy to achieve a wide range of communication and control system capabilities. The term is rooted in the science of cybernetics and Norbert Wiener’s pioneering work in electronic communication and control science, a forerunner to current information theory and computer science. Through its electromagnetic nature, cyberspace integrates a number of capabilities (sensors, signals, connections, transmissions, processors, controllers) and generates a virtual interactive experience accessed for the purpose of communication and control regardless of a geographic location. In pragmatic terms, cyberspace allows the interdependent network of information technology infrastructures (ITI), telecommunications networks—such as the internet, computer systems, integrated sensors, system control networks and embedded processors and controllers common to global control and communications. As a social experience, individuals can interact, exchange ideas, share information, provide social support, conduct business, direct actions, create artistic media, play games, engage in political discussion, and so on. The term was coined by the cyberpunk science fiction author William Gibson. Now ubiquitous, the term has become a conventional means to describe anything associated with computers, information technology, the internet and the diverse internet culture. Cyberspace is recognized as part of the US National Critical Infrastructure .
