Unlike star or mesh topology, a bus topology is a multi-point connection between the nodes or devices on the network. A long cable works as backbone of the network. All the different nodes in the network connects at different points on the main cable. A connection point in the main cable for a node or device is the nearest point for the node.
Star topology is one of the four basic topologies of network communication. In star topology, all network devices connects to a controller or hub. This controller or hub enables communication among the network devices. Devices does not connect directly to each other as in Mesh topology.
