Difference Between Ring Topology and Star Toplogy

There are number of topologies in computer networking, star topology, ring topology, bus topology and mesh topology.

Difference Ring Topology & Star Topology

In star topology multiple nodes can only do their communication by using a central hub whereas in ring topology there is a direct communication link between two nodes, No central technology use that transfer their data.

Ring Topology

  • Cable forms closed ring or loop with all computers and devices arranged along ring.
  • Data Travels from device to device around entire ring, in one direction.
  • Primarily is used for LAN's but also is used in WAN's.
Ring Topology Advantages:
  • Data is quickly transferred.
  • The transmission of data is relatively simple as packages travel in one direction only. 
Ring Topology Disadvantages:
  • Data packets must pass through every computer between the sender and recipient therefore, this makes it slower.
  • If any of the nodes fail then the ring is broken and data cannot be transmitted successfully.
  •  It is difficult to troubleshoot the ring.

Star Topology

A type of topology where CPU's are connected via medium called hub. A topic which you need to read on Star Topology.
  • All devices connect to a central device, called hub.
  • All data transferred from one computer to another passes through hub. 
Star Topology Advantages:
  • Easy to install and wire.
  • Security can be implement in the hub/switch.
  • Easy to detect faults and to remove parts.
Star Topology Disadvantages:
  • Requires more cable length than a linear topology.
  • If the hub or concentrator fails, nodes attached are disabled.
  • More expensive than linear bus topologies because of the cost of the concentrator.
