CSMA or CD: The management of collision in the network can also be done with the implementation of Protocol – Carrier Sense Multiple Access or Collision Detection. This is a type of contention protocol which would define as to how to respond when the detection of collision is done.
Even when the two devices attempt to simultaneously transfer the packages simultaneously. Th Ethernet permits each of the devices to send messages at any point in time without waiting for the network permission. So once the collision is detected, each of the devices that transmit packet delays the random amount of time before the packet is retransmitted. In case if another collision occurs, the device would wait twice as long before the retransmission is tried upon.
