What is Ring Topology ?

Ring Topology Definition

Here information is transmitted from one computer to a different through a hoop structure. The PC that would like to send some information sends to its immediate neighbor that forwards to its immediate neighbor so on. Finally the info passes through the whole ring and reach the sender that removes the info from ring network. it's typically free from collision. It is slow. If a line break then entire network can fail.

What is Star Topology? 

What is Bus Topology? 

Advantages of Ring topology:

Reduced chances of knowledge collision as each node release a knowledge packet after receiving the token.

Token passing makes ring topology perform better than bus under heavy traffic.

No need of server to regulate connectivity among the nodes.

Equal access to the resources.

Disadvantages of Ring topology:

In Unidirectional Ring, a knowledge packet must undergo all the nodes.

Ex: Let’s say A, B, C, D, and E are a neighborhood of the ring network. the info flow is from A towards B and henceforth. during this condition, if E wants to send a packet to D, the packet must traverse the whole network to succeed in D.

Single point of failure, meaning if a node goes down entire network goes down.
