- - 8Ring topology advantage+Easy to install
+Easy to add extra workstation
+Uses less cable that a star network
+ - 9Ring topology disadvantage-If a single computer is switched off or faulty, then diagnose problems with the netwrok
- 10Star topology advantages+The most reliable topology because if one computer is switched off or fault the network.
-improved security compared to bus and ring, because the switch and hub regulate data transfer - 11Star topology disadvantages-Expensive network setup because of all the hardware needed and a lot of cable to connect different computers to the hub/server/switch
