A host on a bus network is called a station. In a bus network, every station will receive all network traffic, and the traffic generated by each station has equal transmission priority. A bus network forms a single network segment and collision domain. In order for nodes to share the bus, they use a media access control technology such as carrier sense multiple access (CSMA) or a bus master.
Advantages and disadvantages
- Very easy to connect a computer or peripheral to a linear bus.
- Requires less cable length than a star network resulting in lower costs.
- The linear architecture is very simple and reliable.
- It works well for small networks.
- It is easy to extend by joining cable with connector or repeater.
- If one node fails, it will not affect the whole network.
- The entire network shuts down if there is a break in the main cable or one of the T connectors break.
- collisions occur in the network resulting in packet loss.
- This topology is slow with many nodes on the network.
- It is difficult to isolate faults in the network.
