CSMA/CD: Carrier Sense Multi-Access/Collision Detection

Carrier Sense Multi-Access (CSMA) is a network access method used on shared network topologies such as Ethernet for a node to verify the absence of other traffic before transmitting on a shared physical medium. Collision Detection (CSMA/CD) is one of the methods often used in Ethernet to avoid possible collision, in which when a collision occurs, and both devices stop transmission, wait for a random amount of time, then retransmit.
