$12\mathrm{.}1\mathrm{.}3$ CSMA$/$CD

The CSMA method does not specify the procedure following a collision. Carrier sense multiple access with collision detection $($CSMA$/$CD$)$ augments the algorithm to handle the collision.

In this method, a station monitors the medium after it sends a frame to see if the transmission was successful.

If so$,$ the station is finished.

If$,$ however, there is a collision, the frame is sent again.
