Bus topology

  • a single cable is the backbone of the network
  • connects each computer to scanners, printers, server and router. 


  • cheap to install as only one wire
  • suitable for small networks only


  • performance becomes slower if more computers are added
  • if the cable fails, so does the whole system
  • the length of the cable restricts the amount of devices that are able to connect

Ring topology

  • each device is connected to two neighbouring devices
  • messages passed around in the same direction
  • often found in schools and offices


  • the messages are passed through devices so no central server is needed


  • failure of any cable can crash the whole network
  • can be slow if lots of data is needed to be transferred
  • alterations may impact the whole performance

Star topology

  • has a central hub which each device connects to
  • used in homes
  • require more cable


  • can easily make alterations without causing a failure
  • isolation of each device in network


  • relies on central hub so if that fails so does the whole system
  • many cables required

Mesh topology

  • every component is connected to every other piece to transfer data


  • if a node fails, the system will still work but slightly less efficiently
  • very fast


  • it requires lots of wires so it is expensive
