Each device is connected to its own port on a hub, just like the star topology. A tree or "star of stars" topology interconnects hubs in a hierarchy, so one hub at the top of the hierarchy will connect to more hubs, which will break off to clients and even more hubs. The diagram below shows a simple tree topology.

The highly flexible tree topology lets you add users by simply adding a hub. Centralized monitoring and administration makes it easier to control a large network or reconfigure it. Isolating problems is easy, and if one node goes down, the rest of the network stays online.

An extensive tree topology will be more expensive to administer than any of the previous topologies due to its size and complexity. If a hub cable or a hub fails, a portion of the network will go down.
