In cyberculture, the Internet and other networks that flow into it are altogether sometimes called "the matrix." In William Gibson's science-fiction novel, Neuromancer," the matrix" is a vast sea of computing resources that can be visualized by the user, is accessible at many levels, and is lit up more intensely in the areas of greatest activity. The hero, Case, "jacks in" to the matrix through wiring that is (perhaps, since it's not entirely clear) integrated with his brain and explores the matrix with a "deck" or computer console that provides a holographic view.
