Cultural definitions for cyberspace

cyberspace

The space in which computer transactions occur, particularly transactions between different computers. We say that images and text on the Internet exist in cyberspace, for example. The term is also often used in conjunction with virtual reality, designating the imaginary place where virtual objects exist. For example, if a computer produces a picture of a building that allows the architect to “walk” through and see what a design would look like, the building is said to exist in cyberspace.
