Advantages and disadvantages of a bus network

The advantage of a bus network is:

  • it is cheap to install, as it doesn't require much cable

The disadvantages of a bus network are:

  • if the main cable fails or gets damaged the whole network will fail
  • as more workstations are connected the performance of the network will become slower because of data collisions
  • every workstation on the network "sees" all of the data on the network 鈥 this is a security risk
