CSMA/CD
carrier sense multiple access with collision detection

Collisions are resolved using carrier sense multiple access with collision detection in which the competing packets are discarded and re-sent one at a time.

A scheme known as carrier sense multiple access with collision detection (CSMA/CD) governed the way the computers shared the channel.

A protocol called Carrier sense multiple access with collision detection or CSMA/CD was designed to deal with these problems.

Carrier sense multiple access with collision detection or CSMA/CD is a protocol (or rule) used by computer ethernet networks.

Carrier sense multiple access with collision detection (CSMA/CD) is a Media Access Control method in which:

The process is set in the Ethernet Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.

Collisions - Ethernet uses a process called CSMA/CD (Carrier Sense Multiple Access with Collision Detection) to communicate across the network.

When Ethernet became Fast Ethernet, it continued to use the Carrier Sense Multiple Access With Collision Detection (CSMA/CD) mechanism to manage traffic on the network cable.

IEEE Std 802.3, which defines all Ethernet variants, for historical reasons still bears the title "Carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications".

Examples are the retransmission of frames in carrier sense multiple access with collision avoidance (CSMA/CA) and carrier sense multiple access with collision detection (CSMA/CD) networks, where this algorithm is part of the channel access method used to send data on these network.
