CSMA/CD

CSMA/CD (Carrier Sense Multiple Access/Collision Detection) is a media access control method used in early Ethernet technology with shared Bus Topology. It ensures that stations do not transmit data simultaneously, avoiding collisions. When multiple stations attempt to send data, CSMA/CD helps detect and manage collisions to ensure successful data transmission. Although it is no longer commonly used in modern Ethernet networks with full-duplex communication, CSMA/CD is still supported. This protocol was essential for effective data transfer in older Ethernet systems.
