A bus network is a network topology in which nodes are directly connected to a common linear half-duplex link called a bus.
A host on a bus network is called a Station or WorkStation. In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority. So, there is no relationship like Master-Slave.
The bus network can be a perfect example of Peer-to-Peer network.
- It works well for small networks.
- It is easy to extend by joining cable with connector or repeater.
- Very easy to connect a computer or peripheral to a linear bus.
- Requires less cable length than a star topology resulting in lower costs.
- Entire network shuts down if there is a break in the main cable or one of the T connectors break.
- A Plenty of packet collisions on the network, which results in high amounts of packet loss.
- Terminators are required at both ends of the main cable.
- Difficult to identify the problems if the whole network goes down.
