Token Ring network

Token Ring network
   IBM's implementation of the token-ring network architecture, which uses a token-passing protocol transmitting at 4 or 16Mbps. Using standard telephone wiring, a Token Ring network can connect a maximum of 72 devices; with shielded twisted-pair (STP) wiring, each ring can support a maximum of 256 nodes. Although it is based on a closed-loop ring structure, a Token Ring network uses a star-shaped cluster of as many as eight nodes, all attached to the same wiring concentrator or Multistation Access Unit (MAU). The MAUs are then connected to the main ring circuit.
   A Token Ring network can include personal computers, minicomputers, and mainframes. The IEEE 802.5 standard defines token-ring networks.
