Q
  1. The host listens to the LAN media to determine whether it is in use.
  2. If the LAN media is not being used, the host transmits its communication.
  3. While transmitting, the host listens for collisions (in other words, two or more hosts transmitting simultaneously).
  4. If a collision is detected, the host transmits a jam signal.
  5. If a jam signal is received, all hosts stop transmitting. Each host waits a random period of time and then starts over at step 1.
