Answer: In Ring Network, not data collisions occur due to token passing, where only one node transmits at a time, making sure orderly and collision-free data flow.
Due to the below reasons, there are no data collisions on a ring network.
Token Passing
The Ring networks uses the token passing protocol where a special token is passed sequentially from one node to another. Only the node possessing the token can transmit data, making sure that no collisions occur as only one node can send data at a time.
Unidirectional Data Flow
Data in a ring network flows in a unidirectional manner, either clockwise or counterclockwise. This make sure that data packets do not collide as they move along the ring, which follows a structured path.
No Contentions
As only one node has control of the token and can transmit data, there are no contentions or conflicts between nodes trying to send data simultaneously, this prevents the chances of data collisions.
Proper Resource Utilization
Token passing provides proper utilization of network resources by allowing nodes to transmit data in an orderly and controlled manner, this prevents data collisions that can lead to retransmissions and network congestion.
Improved Reliability
The absence of data collisions improve the reliability of communication in a ring network, as data packets can be transmitted smoothly without disruptions that are caused by overlapping transmissions.
