(1) A metaphor for describing the non-
physical terrain created by
computer systems. Online systems, for example, create a cyberspace within which people can communicate with one another (via
e-mail), do research, or simply window shop. Like physical space, cyberspace contains
objects (
files, mail messages,
graphics, etc.) and different
modes of transportation and delivery. Unlike real space, though, exploring cyberspace does not require any physical movement other than pressing
keys on a
keyboard or moving a
mouse.
Some programs, particularly computer games, are designed to create a special cyberspace, one that resembles physical reality in some ways but defies it in others. In its extreme form, called virtual reality, users are presented with visual, auditory, and even tactile feedback that makes cyberspace feel real.
The term was coined by author William Gibson in his sci-fi novel Neuromancer (1984).
