CSMA\CD means that when a Clint want to send a signal if is it free it will send the signal and it happens in other Clint at the same time so the signal will crash and then they will try again later after period of time.
Pesistentent CSMA sense the channel continuously where as non pesistent CSMA resense the channel after a time decided randomly or based on probabilistic work----- Sanjay Bhaumick
CSMA/CD: Carrier Sense Multiple Access / Collision Detection.
How does CSMA minimize fading?
*** In CSMA/CD it detects that a collision take place and resend the frame that was send. On a wirless network losing bandwidth along with time to detect that a collision took place was not acceptable , so CSMA/CA was utilized. ** CSMA/CD can achieve above 70% efficiency under heavy loads compared to CSMA/CA that can only achieve up to 30% efficiency under heavy loads. CSMA/CA network: A network in which the medium access control protocol requires carrier sense and where a station always starts transmission by sending a jam signal; if there is no collision with jam signals from other stations, it begins sending data; otherwise, it stops transmission and then tries again later. CSMA/CD network: A bus network in which the medium access control protocol requires carrier sense and in which exception conditions caused by collision are resolved by retransmission
It signals to the network that its data was damaged in a collision, waits a brief period of time before checking the network for activity, and then retransmits the data.
Devices listen to the media and transmit data only when they cannot detect another signal on the media. All devices on the media can hear all communications When a collision occurs, all devices stop transmitting for a randomly generated period of time.
It signals to the network that its data was damaged in a collision, waits a brief period of time before checking the network for activity, and then retransmits the data.

It is prevent all connected network cards sending at the same time.

This is the Algorithm use by CSMA/CD as a wait period to allow other devices on the network to access the media.
