  Write the differences between star and bus topology of network? Star Topology Bus Topology In a star topology, Each device has a dedicated point-to-point connection to a central controller, called a hub. The devices are not directly linked to each other. In a bus topology, One long cable acts as a backbone to link all the devices in the network. The controller acts as an exchange. If one device wants to send data to another, it sends the data to the controller which then relays the data to the other connected device. In bus topology, nodes are connected to the bus cable by drop lines and taps. The drop line is a connection running between the device and the main cable. A tap is a connector. In bus topology, signal always travelling along backbone, so some energy transfer into heat, so there should be limited number of nodes in bu...
