IBM's implementation of the token-ring network architecture; it uses a token-passing protocol transmitting at 4 or 16 mbps. Using standard telephone wiring, a Token Ting network can connect up to 72 devices; with shielded twisted-pair wiring, the network can support up to 260 nodes.
A local area network configuration that forms a closed ring of machines where network traffic is managed through the passing of digital tokens. A machine on the network cannot send data unless it "has the floor" via the token. A token ring can operate at up to 4 megabits (4 million bits) per second.
a LAN in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time
