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. 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.
- Easiest network topology for connecting computers or peripherals in a linear fashion.
- Requires less cable length than a star topology.
Disadvantages of bus topology
- Difficult to identify the problems if the whole network goes down.
- It can be hard to troubleshoot individual device issues.
- 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.
