Difference between Star and Ring Topology

Prerequisite – Network Topologies
Star Topology:
In Star topology, the nodes are connected to the central hub or router in which the information is travel from central hub or router to all the nodes. There are n links in Star topology, if there are n nodes. The nodes are connected to each other completely via dedicated link in which the information is travel from nodes to nodes.A new cable is added to the central hub to add a new node in star topology.





Ring Topology:
In Ring topology, every node is connected to it’s left and right side nodes in which the information is travel from nodes to nodes in ring manner in one direction.There are also n links in ring topology like star topology, if there are n nodes present. In ring topology, to add a new node the entire connection must be broken down.







Difference between Star and Ring Topology:

S.NO Star topology Ring Topology
1. In star topology, the nodes are connected to the central hub or router. In ring topology, every node is connected to it’s left and right side nodes.
2. In star topology, only hub is failure point. In ring topology, every nodes are failure point.
3. The cost of star topology is high. The cost of ring topology is low.
4. In star topology, the information is travel from central hub or router to all the nodes. In ring topology, the information is travel from nodes to nodes in ring manner in one direction.
5. The cables are required in star topology more than the ring topology. The cables are required in ring topology less than the star topology.
6. There are n links in Star topology, if there are n nodes. There are also n links in ring topology, if there are n nodes present.
7. A new cable is added to the central hub to add a new node. Whereas to add a new node in ring topology, the connection must be broken.
