What are the functions of bus topology?

Bus topology is a network configuration where all devices share a single communication line or cable, known as the bus. Its primary functions include facilitating data transmission between devices and enabling easy addition or removal of nodes without disrupting the entire network. This topology is cost-effective for small networks due to its minimal cabling requirements. However, it can be less reliable than other topologies, as a failure in the bus can lead to network disruption for all connected devices.
