Bus topology is a type of network where every device is connected to a single cable which runs from one end of the network to the other. This type of type of topology is often referred to as line topology. In a bus topology, data is transmitted in one direction only. If the bus topology has two endpoints then it is referred to as a linear bus topology. Smaller networks with this type of topology will generally use an RJ45 cable to link devices together.

Advantages

There are a number of reasons why bus topologies are used in smaller networks. One of the main reasons is that they keep the layout simple. All devices are connected to a single cable so you don’t need to manage a complex topological setup.

The layout also helps make bus topologies cost effective because they can be run with a single cable. In the event that more devices need to be added then you can simply join your cable to another cable.

Disadvantages

However, relying on one cable does mean that bus topologies have a single point of failure. If the cable fails then the entire network will go down. A cable failure can cost organizations a lot of time while they attempt to resume service. Further to this, if you have lots of network traffic then the performance of your network will decrease significantly as all the data will be travelling through one cable.

This limitation makes bus topologies suitable only for smaller networks. The primary reason is that the more nodes you have, the slower your transmission speeds are going to be. It is also worth noting that bus topologies are limited in the sense that they are half-duplex, which means that data can’t be transmitted in two opposite directions simultaneously.
