Carrier sense multiple access with collision detection (CSMA/CD) is a Media Access Control method in which:
- a carrier sensing scheme is used.
- a transmitting data station that detects another signal while transmitting a frame, stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame.
CSMA/CD is a modification of pure carrier sense multiple access (CSMA). CSMA/CD is used to improve CSMA performance by terminating transmission as soon as a collision is detected, thus shortening the time required before a retry can be attempted.

Famous quotes containing the words carrier, sense, multiple, access and/or collision:
“Because language is the carrier of ideas, it is easy to believe that it should be very little else than such a carrier.”
—Louise Bogan (1897–1970)
“The dignity of the artist lies in his duty of keeping awake the sense of wonder in the world. In this long vigil he often has to vary his methods of stimulation; but in this long vigil he is also himself striving against a continual tendency to sleep.”
—Gilbert Keith Chesterton (1874–1936)
“... the generation of the 20’s was truly secular in that it still knew its theology and its varieties of religious experience. We are post-secular, inventing new faiths, without any sense of organizing truths. The truths we accept are so multiple that honesty becomes little more than a strategy by which you manage your tendencies toward duplicity.”
—Ann Douglas (b. 1942)
“Whilst the rights of all as persons are equal, in virtue of their access to reason, their rights in property are very unequal. One man owns his clothes, and another owns a country.”
—Ralph Waldo Emerson (1803–1882)
“I know my fate. One day my name will be tied to the memory of something monstrous—a crisis without equal on earth, the most profound collision of conscience, a decision invoked against everything that had previously been believed, demanded, sanctified. I am no man, I am dynamite!”
—Friedrich Nietzsche (1844–1900)
