Alternatively 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 an RJ-45 network cable is used to connect them 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.
