All systems are connected to a common, shared media (Multiple Access). A system wishing to transmit listens to the media to determine if it is free for transmission (Carrier Sense). 2. If the media is available, the end system transmits its frame. 3. If another system transmits at the same time, there is a collision (Collision Detection). In this case, both systems wait a random period of time before attempting another transmission. We say the media is half-duplex because it is shared and when two end systems are communicating, only one system can transmit at a time.
