What are network topologies? Explain Ring, Bus and Star topology.A network topology describes the layout of a network. It describes how different nodes and elements are connected to each other. Different types of topology:
1. Ring:-
a. All nodes connected with another in a loop.
b. Each device is connected to one or more another device on either side.
2. Bus
a. All nodes connected to a central and a common cable called as a back bone.
b. In bus topology, the server is at one end and the clients are connected at different positions across the network.
c. Easy to manage and install.
d. If the backbone fails, the entire communication fails.
3. Star
a. All nodes connected to a central hub.
b. The communication between the nodes is through the hub.
c. Relative requires more cables as compared to BUS. However if any node fails, it wont affect the entire LAN.
