token-ring network Last modified: Friday, August 16, 2002
(1) A type of computer network in which all the computers are arranged (schematically) in a circle. A token, which is a special bit pattern, travels around the circle. To send a message, a computer catches the token, attaches a message to it, and then lets it continue to travel around the network. Also see token passing. For network diagrams, see Network Topology Diagrams in the Quick Reference section of Webopedia. (2) When capitalized, Token Ring refers to the PC network architecture developed by IBM. The IBM Token-Ring specification has been standardized by the IEEE as the IEEE 802.5 standard.
