What happens to stations when a collision is detected after transmission?

They stop transmitting data immediately and send a jamming signal (correct)

They switch to a different transmission frequency

They continue transmitting data at a slower rate

They abort the transmission process and shut down

What algorithm is used by stations to wait before re-transmitting after a collision?

Linear backoff algorithm

Random delay algorithm

Binary exponential backoff algorithm (correct)

Fixed delay algorithm
