ADVANTAGES.
-Easy to configure.
-Easily expandable.
-If one workstation fails does not affect others.
-Allows centralisation of key networking.
DISADVANTAGES.
• Requires more cable than a linear bus.
• If the connecting network device (network switch) fails, nodes attached are disabled and can’t participate in network communication.
• More expensive than linear bus topology due to the value of the connecting devices (network switches)
• If hub goes down everything goes down, none of the devices can work without hub.
• Hub requires more resources and regular maintenance because it’s the central system of star.
• Extra hardware is required (hubs or switches) which adds to cost
• Performance is predicated on the one concentrator i.e. hub.
