# Bus Topology

## Bus Topology

Introduction to Bus Topology:

As you know, there are several types of topology in networking.

These different networking layouts reflect different ways to connect nodes to a network. One of these types of topology is called “bus topology.”

Bus topology is a fairly simple network layout that supports any number of nodes. Just as with other layouts, this method of topology has its own advantages and disadvantages. By examining how this layout is structured, we can begin to understand why and how it works, and why it has the advantages and disadvantages that it does.

How Bus Topology Works?

Understanding the structure of bus topology is key to understanding how and why it works. With bus topology, different nodes are all separately located to the same main cable. In order to understand this layout, first you should imagine one main cable that connects the network.

Different nodes can be connected to this cable. It’s important to note that these nodes are not connected to one another. Instead, they are all independently connected to this main cable. There is no limit to the number of nodes that can be added to this network in theory, but the number of connected nodes can actually affect the quality of the network.

When you compare this network layout to point to point topology, it’s clear to see that it has some advantages. For one, whereas point to point topology requires that there can only be two nodes, bus topology allows for multiple nodes.

This means that several different computers, routers, or other data devices can be connected to this network. This makes bus topology a better choice for small businesses or small schools and office spaces because of its ability to support a larger network.
