Carrier Sense Multiple Access With Collision Avoidance or CSMA/CA is a Access Method or(protocol, or a rule ) which use in Eternet Networks. In CSMA/CA access method before A host sent informations on the wire, it will "sense" as well as to see if the wire is free of signals. If the wire is free, it will try to "avoid" a collision by sending a piece of "dummy" data on the wire first to see weather it collides with other data if it is not collide, the host in affect assumes "If my dummy data did not collide, than the real data will not collide," and it submits the real data on the wire. --Mr.K0ll3r 14:57, 19 April 2015 (UTC)Mr.K0ll3r
