The IEEE later adopted Token Ring as standard 802.5. There is also a Token Bus standard (802.4), which is similar to Token Ring except it uses a bus topology instead of a ring topology. The principal ...

Conforming to the IEEE 802.5 standard, the Token Ring access method connects up to 255 nodes in a star topology at 4, 16 or 100 Mbps. All stations connect to a central wiring hub called the ...

So in a non-switched environment, Token Ring had some technical advantages over Ethernet. Token Ring did help to institute Star topology. Being a bus, Ethernet was conventionally deployed at the ...

Token Ring naturally uses the ring architecture. A mesh topology is usually found in a wide area network (WAN) to provide redundant paths between locations. See Ethernet and Token Ring.
