WebTruncating the backoff at 1023 keeps the bound from growing too large. If there is no collision, the sender assumes that the frame was probably successfully delivered. That is, neither CSMA/CD nor ... Exponential backoff algorithms can be used to avoid network collisions. In a point-to-multipoint or multiplexed network, multiple senders communicate over a single shared channel. If two senders attempt to transmit a message at the same time, or "talk over" each other, a collision occurs and the messages are damaged or lost. Each sender can then back off before attempting to retransmit the same message again.
