Assurance vs Audit

Bus Topology is one of the most simple network topologies. In a bus topology, all the nodes are linked into a single cable. This central cable is the backbone of the network and therefore it is known as the Bus. Every node sends and receives through this Bus.

A Bus Topology consists of two or more nodes that are connected through one central cable. Every single computer has its own NIC with which every computer can both send and receive traffic. This means that computers cannot communicate directly with each other; they need the help of the Node at the end of the bus. It's for this reason that most LANs use Bus Topologies; they are very cheap but also lose massive amounts of data due to collisions.

The sending computer sends the info to the destination computer through the bus. the info moves from one computer to the opposite within the network .Each computer checks the address. If it matches with the address of a computer the pc keeps the info. Otherwise, the info moves to the subsequent computer.

Advantages Bus Topology

     • Easy to add/remove nodes in a network 

• It is simple and easy to use.

     • It is less expensive.

     • It requires a small length of cable to connect the computer. 

     • If one node fails it does not affect the rest of the network.

    • Required only cable.

    • It broadcast the messages to each device which are linked through the cable.

     • Other devices will not affect In case of computer failure.

Disadvantage of Bus Topology

     • It only supports a small number of computers. 

     • The network speeds slow down as the number of computer increase.

    • If there is an issue with the cable the whole network will be failed.

    • The length of the cable is limited.

• In Bus Topology passing the message from one place to another place takes more time.

    • In Bus Topology data is transmitted only in one direction.

Conclusion

Even though Bus Topologies are getting obsolete due to different network topologies, they are still the cheapest way to create a local area network that can connect multiple computers at once. Network nodes attaching through NIC ports using one central cable makes it easy for every computer on the bus to send and receive data. 

Due to collisions, however, massive amounts of data can be lost within seconds. The collision may also cause disruptions in the flow of traffic which makes it slow down sometimes. Nevertheless, this technology is still very much used today because it's reliable and accessible for most purposes regarding networking across LANs.
