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:
“It is the corpse of the bourgeoisie that separates us. With us, it is that class that is the carrier of the chromosome of banality.”
—Jean Baudrillard (b. 1929)
“The confusion is not my invention. We cannot listen to a conversation for five minutes without being aware of the confusion. It is all around us and our only chance now is to let it in. The only chance of renovation is to open our eyes and see the mess. It is not a mess you can make sense of.”
—Samuel Beckett (1906–1989)
“... 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)
“Make thick my blood,
Stop up th’ access and passage to remorse,
That no compunctious visitings of nature
Shake my fell purpose.”
—William Shakespeare (1564–1616)
“When the wind carries a cry which is meaningful to human ears, it is simpler to believe the wind shares with us some part of the emotion of Being than that the mysteries of a hurricane’s rising murmur reduce to no more than the random collision of insensate molecules.”
—Norman Mailer (b. 1923)
