何謂Cyberspace ?

Cyberspace

a computer network consisting of a worldwide network of computer networks that use the TCP/IP network protocols to facilitate data transmission and exchange.

(Coined by {William Gibson})      Notional "information-space" loaded with visual cues andnavigable
with brain-computer interfaces called "cyberspace
decks"; a characteristic prop of {cyberpunk} SF.  In 1991
serious efforts to construct {virtual reality} interfaces
modelled explicitly on Gibsonian cyberspace were already under
way, using more conventional devices such as glove sensors and
binocular TV headsets.  Few hackers are prepared to deny
outright the possibility of a cyberspace someday evolving out
of the network 

Cyberspace is the electronic medium of computer networks, in which online communication takes place. It is the domain of electromagnetics readily identified with the interconnected information technology required to achieve the wide range of system capabilities associated with the transport of communication and control products and services.

Origins of the term

The word "cyberspace" (from cybernetics and space) was coined by science fiction novelist and seminal cyberpunk author William Gibson in his 1982 story "Burning Chrome" and popularized by his 1984 novel Neuromancer. The portion of Neuromancer cited in this respect is usually the following:

Cyberspace. A consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts... A graphic representation of data abstracted from the banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the nonspace of the mind, clusters and constellations of data. Like city lights, receding.

Despite its originally negative overtone, the term is no longer implies a negative connotation.

Gibson later commented on the origin of the term in the 2000 documentary No Maps for These Territories:

All I knew about the word "cyberspace" when I coined it, was that it seemed like an effective buzzword. It seemed evocative and essentially meaningless. It was suggestive of something, but had no real semantic meaning, even for me, as I saw it emerge on the page.
