Also known as: CSMA/CD

Quick Summary

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network access method used in broadcast networks to manage channel allocation and prevent simultaneous transmissions that could lead to data collisions. In CSMA/CD, a node first listens to the channel to ensure it's not busy before transmitting. If a collision does occur, meaning two nodes transmit at the same time, the nodes detect this and stop transmitting immediately, then wait a random amount of time before attempting to send again. This method is a key feature of wired Ethernet.1
