Answer Posted / anil
CSMA/CD is a media access control mechanism used in Ethernet
to recover from frame collision. The following steps are
followed to recover from a collision.
Step 1: Before an Ethernet device sends a frame on the
Ethernet cable, it listens to find if another device is
already transmitting a frame (Carrier Sense).
Step 2: Once the device finds that other devices are not
transmitting any frame, it starts transmitting the frame. If
two devices detect that the Ethernet cable is free at the
same time, then both will start transmitting the frames
(Multiple Access). This will result in collision.
Step 3: The Ethernet devices while transmitting the frames,
also listen for the collision. (Collision Detect).
Step 4: If they detect a collision, both the devices stop
sending the frame (back off).
Step 5: They retry the transmission after a logarithmic
time-out period. This process is repeated till the frame is
transmitted successfully, for a maximum of 16 times. The
frame is discarded after the 16th retry.

The physical layer service is a non-confirmed service. Assume that some bits of data are lost during transmission over physical media, which layer will detect the loss and take some remedial measures. Explain any one method clearly depicting how this operation is performed.
