Token ring hubs are devices used to connect computers and other devices to a network. Token ring was developed in the 1980s and is one of the earliest networking technologies. With a token ring network, computers pass a token from one device in a network to the next in the ring until the desired destination is reached.

One problem with this network is that if a computer is not on, the chain is broken and the transmission will fail. A token ring network hub eliminates that problem by bypassing computers that do not have a connection or aren't turned on.

Token ring networks will become harder to repair and support as technology moves farther away from them. There are some reasons that companies choose to keep using token ring networking hubs and networks:

1. Token ring networking hubs offer secure, reliable data transmission.

2. The cost for upgrading to newer technology may be prohibitive,

3. Current IT staff and management is familiar with token ring topology and support.
