Token ring
Token ring or 802.5 is a network where all computers on the network are connected in a circle fashion. The term token is used to describe a segment of information that is sent through that circle; when a computer on the network is able to decode that token, the information is received on that computer. The token ring is used by ARCNET, token bus and FDDI. Today, 802.5 and Token ring is also considered inactive.
