Cyberspace refers to the nonphysical environment created by joined computers interoperating on a network. In cyberspace, computer operators interact in ways similar to the real world, except cyberspace interaction does not require physical movement beyond typing. Information can be exchanged in real time or delayed time, and people can shop, share, explore, research, work or play.
The Internet forms the largest cyberspace environment, housing many sub-environments within it. These include the World Wide Web (Web), USENET newsgroups and Internet Relay Chat (IRC).
