Bus topology is a type of network topology in which all devices are connected to a single cable called a "bus". In this topology, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority. Bus topology forms a single network segment and collision domain. The following are the advantages and disadvantages of using a bus topology:
Advantages:
- It works well when you have a small network.
- Its the easiest network topology for connecting computers or peripherals in a linear fashion.
- It requires less cable length than a star topology.
Disadvantages:
- 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 the bus cable is damaged or severed, the entire network will be affected.
Bus topology is commonly used in small to medium-sized local area networks (LANs), where it can be used to connect devices such as computers, printers, and other peripherals. It can also be used in industrial control systems and other specialized applications.
