Token Ring


Definition
As defined in IEEE 802.5, a communications method that uses a token to control access to the LAN. The difference between a token bus and a Token Ring is that a Token Ring LAN does not use a master controller to control the token. Instead, each computer knows the address of the computer that should receive the token next. When a computer with the token has nothing to transmit, it passes the token to the next computer in line.
