Carrier sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by transmitting only when the channel is sensed to be "idle".
It is particularly important for wireless networks, where the collision detection of the alternative CSMA/CD method is not possible for technical reasons.
CSMA/CA is a protocol that operates in the Data Link Layer (Layer 2) of the OSI model.

Famous quotes containing the words carrier, sense, multiple, access, collision and/or avoidance:
“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)
“Comedy deflates the sense precisely so that the underlying lubricity and malice may bubble to the surface.”
—Paul Goodman (1911–1972)
“There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period.”
—Auguste Rodin (1849–1917)
“Lesbian existence comprises both the breaking of a taboo and the rejection of a compulsory way of life. It is also a direct or indirect attack on the male right of access to women.”
—Adrienne Rich (b. 1929)
“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)
“The American Dream, the idea of the happy ending, is an avoidance of responsibility and commitment.”
—Jill Robinson (b. 1936)
