Q. Data transmission in Bus Topology ?
Bus Topology:This topology shares a single path or link way among all users. This common single path way is called bus. In this topology, link serves as a high way for all data signals and users connect on to the bus at their node location. In bus configurations, network control isn't centralized to a particular node. Here control is distributed among all nodes connected to the LAN. Data transmission on a bus network is generally in the form of small packets comprising user addresses and data. When one user/node desires to transmit data to another station, it monitors bus to determine if it's currently being used. If no other nodes/users are communicating over the network, monitoring node/user can start to transmit its data. Every node should monitor all transmission on the network and determine which are intended for them.
