A bus topology is a type of network configuration where all the devices or nodes in the network are connected to a single, central cable known as the bus, backbone or trunk. This common shared path serves as the medium for data transmission and communication amongst the nodes.

How Bus Topology Works

In a bus topology, every node has a unique address that identifies it on the network. When a node wants to communicate with another node in the network, it broadcasts a message containing the destination node’s address as well as its own address. All the nodes connected to the bus receive the message, but only the intended recipient with the matching address responds.

Advantages of Bus Topology

Disadvantages of Bus Topology

Bus topology can be an effective solution for small networks with minimal devices. However, as network size and complexity increase, other topologies such as star, ring, or mesh may be more suitable for maintaining efficiency and reliability.
