Carrier sense multiple access/collision avoidance. CSMA/CA is a protocol that allows each node to sense whether or not a channel is in use before attempting to transmit information. CA is an algorithm by which channel time is reserved to avoid collisions.
(Carrier Sense Multiple Access/Collision Avoidance) - A method of data transfer that is used to prevent data loss in a network.
802.11 WLANs use CSMA/CA to minimize collisions by listening and waiting for a clear channel before transmitting. If the channel is not clear, devices wait for a random timer to expire before listening again. The timer will be reset as many times as necessary. Back

Carrier Sense Multiple Access/Collision Avoidance. The principal media access control strategy used in 802.11 networks to avoid data collisions. It is a "listen before talk" method of minimizing collisions. The network node checks to see if the transmission channel is clear before a data packet is sent. (See collision avoidance, CSMA/CD). close
Carrier Sense Multiple Access with Collision Avoidance. CSMA/CA is only different with CSMA/CD in that CSMA/CA employs collision avoidance scheme instead of collision detection. In CSMA/CA, a node sends intention to transmit message before it really transmits any packet. Also see contention, multiple access, collision and Ethernet.
A method of network access not covered by OSI standards and used in AppleTalk networks.
Carrier Sense Multiple Access Collision Avoidance is a network access method in which each device signals its intent to transmit before it actually does so. This prevents other devices from sending information, thus preventing collisions from occurring between signals from two or more devices. This is the access method used by LocalTalk.
Carrier Sense Multiple Access/Collision Avoidance – A protocol for carrier transmission that prevents collisions before they happen.
Short for Carrier Sense Multiple Access/Collision Avoidance. The access protocol used by 802.11 networks to reduce the number of collisions during transmission of competing data traffic in the network.
Carrier Sense Multiple Access/Collision Avoidance. CSMA/CA is the medium access method used by IEEE 802.11 WLANs.
Carrier sense multiple access/collision avoidance. Access scheme to increase Ethernet performance by having an intelligent hub intervene when a collision is detected and "decide" in a fraction of a nanosecond which message is ahead and will be sent. Generally, the transmitter closest to the hub receives priority transmission because of its proximity to the hub, not necessarily because it transmitted first.
A scheme for controlling network traffic that enables any of multiple nodes to send information over a shared network cable if the cable is free. It avoids collisions by having all nodes signal their intention to transmit before transmitting. If two nodes send intentions to transmit messages at the same time, both nodes wait for random amounts of time before trying again.
