The bus network

In a bus network all the workstations, servers and printers are joined to one cable (the bus). At each end of the cable a terminator is fitted to stop signals reflecting back down the bus.

Advantages and disadvantages of a bus network

The advantages of a bus network are:

  • it is easy to install
  • 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 – this is a security risk
