Final answer:
CSMA/CD and CSMA/CA are both protocols used in computer networks. CSMA/CD is used in Ethernet networks and handles collisions, while CSMA/CA is used in wireless networks and avoids collisions.
Step-by-step explanation:
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) and CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) are both protocols used in computer networks.
CSMA/CD is used in Ethernet networks and is designed to handle collisions when multiple devices are trying to transmit data simultaneously. It uses a method of detecting collisions and retransmitting the data.
CSMA/CA, on the other hand, is used in wireless networks and is focused on avoiding collisions. It uses a method of requesting to transmit data, known as the Request to Send (RTS) and Clear to Send (CTS) mechanism, to ensure that devices take turns transmitting data to avoid collisions.
