CSMA - Carrier Sense Multiple Access

CSMA is a technique used by devices which utilize a shared medium for communication. These devices, often termed nodes, will listen to the medium to try and detect the presence of a carrier signal. A carrier signal being present indicates to the listening device that another node is currently using the medium, therefore the listening node will not attempt to transmit.
