Star-Ring topology
In the Star-Ring topology, the computers are connected to a central component as in a star network. These components, however, are wired to form a ring network.
Like the star-bus topology, if a single computer fails, it will not affect the rest of the network. By using token passing, each computer in a star-ring topology has an equal chance of communicating. This allows for greater network traffic between segments than in a star-bus topology.
