ring topology


  • If a single machine is switched off, the network doesn't work
  • If a cable breaks, the network doesn't work
    • Data must pass through every computer until it reaches its destination. This can make it slower than other network layouts.
    • If there are any problems with the network, they can be difficult to identify the cause.


    • Transmission of data is fairly simple as it only travels in one direction
    • No data collisions
    • Extra computers can be added easily with little effect on performance - although you have to shut down the network to be able to do this
