Bus Topology

Updated: 01/24/2018 by Computer Hope

Bus topologyAlternatively referred to as a line topology, a bus topology is a network setup in which each computer and network device are connected to a single cable or backbone. Depending on the type of network card used in each computer of the bus topology, a coaxial cable or a RJ-45 network cable is used to connect computers together.

The following sections contain both the advantages and disadvantages of using a bus topology with your devices.

Advantages of bus topology

  • It works well when you have a small network.
  • It's the easiest network topology for connecting computers or peripherals in a linear fashion.
  • It requires less cable length than a star topology.

Disadvantages of bus topology

  • It can be difficult to identify the problems if the whole network goes down.
  • It can be hard to troubleshoot individual device issues.
  • Bus topology is not great for large networks.
  • Terminators are required for both ends of the main cable.
  • Additional devices slow the network down.
  • If a main cable is damaged, the network fails or splits into two.
