Top 10 Best Advantages of bus topology

Bus topology is a simple network topology that uses a single central point with multiple outward connections. It is an approach to network design comprising a common point or hub and several branches connected by the main point.

There are many advantages of bus topology. The bus topology is the most common topology used in many networks, including computer and telephone networks.

The bus topology comprises two or more computers connected in a loop through a central device, which acts as an intermediary between all the participants and provides access to external resources such as other computers or servers.

List of 10 Advantages of bus topology

Bus topology can reduce the complexity of networks while providing the same reliability and bandwidth as a star network.

Bus topology is ideally suited to LAN networks which have several computers that communicate with each other through one or more hubs. There are many merits of bus topology. We list some of them below:

1. Easy to connect a device 

The bus topology can easily connect a device straightforwardly and quickly, where it is unnecessary to provision and configure the complicated Controller/Agent configuration.

This helps to reduce the complexity of the network while providing the same reliability and bandwidth as the star network.

2. Lower cost 

With fewer networks to maintain, less costly hardware is required to support a bus-based network. Sharing services with other networks that use the same central device is possible, resulting in even lower costs.

3. Independent work by each device 

Each device in a bus topology can act independently of the other instruments. It is unnecessary to connect the CPU or any specific device to the central hub.

This means that devices can be adapted to needs, and the network will still function as if nothing has changed.

4. Quick Bandwidth Addition 

Physical constraints do not limit the bandwidth of a bus topology but communication limitations among each device.

The restriction on bandwidth in a bus is not because of the speed of individual devices but the number of devices on the network, which creates a bottleneck.

5. Convenience

A bus topology simplifies communication by routing data from one node to the next. Traditionally, the routing of packets was achieved by manual configuration.

In contrast, in a bus topology, all nodes are part of a single network and can easily route data between each other without having to configure routers manually.

6. Supports multiple peripherals 

A bus topology has methods for connecting many peripheral devices directly to the network. This differs from star topology, which does not have a standard routing method for connecting additional peripherals.

A bus topology makes it easy to connect some peripheral devices (for example, printers, scanners, and routers) to the leading network without worrying about multiple connections.

7. Ease of extension

Bus topology is easy to extend or expand further in an existing network. In case there is a need for additional peripheral devices, it is easy to add more widgets to the bus without worrying about configuration issues such as address assignment and name resolution.

8. Supports hot-swapping of devices

Through bus topology, we can disconnect a central device from the network without affecting the connectivity of other devices.

This differs from star topology, where disconnecting a single device from the network will disconnect all other nodes powered by it.

9. Easy to create and administer

We must do manually complex routing in a bus topology network, which makes it more difficult for network administrators. The administrator can easily configure a route between two devices with one command in a bus topology. 

10. Multiple nodes install

Bus topology supports multiple nodes to be installed in a single network. This differs from star topology, which is connected individually to each device in the network, and we must configure manually other devices to allow communication.

Bus topology requires no additional devices such as terminators to complete a connection between nodes and external resources.

We hope this article gives you some information about the advantages of bus topology. The bus network topology permits multiple users to have access to the network simultaneously.

This means that if one user is communicating on the network and the other wishes to, there is no need for one’s data or communication to wait until the other has finished.

This can prevent some frustration associated with data transfer in a multi-user environment where multiple users share a common connection with a central node.
