Network Topologies
Network Topologies The structure of a network including physical arrangement of devices is known as network topology. Consider the following types of topologies:\ 1. Bus topology 2. Star topology 3. Tree topology 4. Point-to-Point 5. Mesh 6. Ring 7. Hybrid Bus Topology: The type of network topology in which all of the nodes of the network are connected to a common transmission medium which has exactly two endpoints all data that is transmitted between nodes in the network is transmitted over this common transmission medium and is able to be received by all nodes in the network simultaneously. Consider the following figure- Advantages of bus topology: Short Cable Length. Easy to expand. Simple Architecture. Disadvantages: Fault diagnosis is difficult. Star Topology: In a star topology, each network host is connected to a central hub with a point-to-point connection. All of the nodes on the ne
