Answer:
When two computers transmit at the same time, the result is a collision. When this happens, each computer's ethernet card waits a random amount of time, then tries again. If a collision happens again, it waits a random amount of time again, with the limit increased.

Answer:
So if two computer attempt to transmit at the same time there’ll be a collision and both frames will fail , each computer must then wait a certain time only a tiny fraction of a second the so called back off delay before attempting to transmit the failed frame again
Fiber optic cable uses glass or plastic optic cable fiber as a conduit for light pulse to transmit data. It has allowed Ethernet to travel farther distance at higher speed.
