Answer: Ring topology handles packet collisions through token passing, allowing only one node to transmit at a time, makes sure the data integrity with error-detection mechanisms like checksums or CRC.
In the ring topology, the packet collisions are mainly handled through the process, which is called as token passing.
Token Passing
A token is actually passed sequentially around the ring from each node to node Only the node with the token can actually send the data, which makes sure that no collision occurs as only one node has the privilege to transmit the data at a time.
Data Integrity
Every node checks the data which it receives to make sure that it matches the proper format and doesn’t have any corrupted data during the transmission. If any errors are being occurred, then the data is retransmitted or corrected using the error checking methods
Token Rotation
When the node ends transmitting the data, it then passes the token to the next node in the ring. This continues data transmission without any conflicts.
Collision Prevention
As only one nod has token at any given time. There are no collisions between the data packets transmission.
Error Detection
Along with the token passing, the error detection techniques like checksums or cyclic redundancy check are used to detect and correct any data errors in the transmission.
