CSMA/CD is a protocol used in Ethernet networks to regulate access to the network medium. Before transmitting data, a device using CSMA/CD first listens to the network to check if it is idle. If the network is busy, the device waits for a random amount of time before attempting to transmit again. If a collision is detected during transmission, the devices involved stop sending data and implement a backoff algorithm to avoid further collisions.

CSMA/CA is a protocol commonly used in wireless networks to avoid collisions. With CSMA/CA,
