Network Topology

Network Topology

1. Bus

   • Advantages
     • cheap to build
     • easy to install
   • Disadvantage
     • Every workstation can see all the data passing through the network meaning that there is very low security.
     • If the main cable is damaged then the whole network will fail

2. Ring

   • Advantage
     • Data can only travel in 1 direction even when lots of devices are connected, meaning no data collisions will occur
   • Disadvantage
     • If the main cable is damaged or even the devices the whole network will fail
     • The Bus and Ring network both use quite old technology
     • When more devices are connected the data will have to travel further meaning that the network will slow down

3. Star

   • Advantage
   • Disadvantage
     • If the main server or a computer server fails, all of the devices in the network will fail
     • It is very expensive to build. e.g. a switch
     • The network provides someone with great knowledge as the servers are very hard t program. If the user does not no they can hire a networking technition but this will add to the cost.
