What is Star Topology?

• Topology in which each of the nodes of the network is connected to a central node with a point-to-point link in a "hub” or “Switch”

• All data that is transmitted between nodes in the network is transmitted to this central node

• Advantages:

•  It is easy to modify and add new computers to a star network without disturbing the rest of the  network.
• If one node or workstation (beside the middle node) goes down, the rest of the network will still be functional.
• The center of a star network is a good place to figure out where the network faults are located.
• You can use several cable types in the same network if the hub you have can handle multiple cable types.

• Disadvantages:

• Requires more cable than a bus topology.

• If the middle node goes down , then the entire network goes down.

• It is more expensive than because all cables must be connected to one central point.
