CSMA/CD

Carrier Sense Multiple Access/Collision Detect. An now-obsolete trafficking protocol used in Ethernet networks, which allowed workstation devices to sense whether the network is free before they transmit data. CSMA/CD was used in shared media Ethernet variants (10BASE5, 10BASE2). Modern Ethernet networks no longer utilize CSMA/CD, but it is still supported for backwards compatibility.

Lengths of the copper segments within the same collision domain (if not given, 100 meters per segment must be assumed); and
This approach bogged down communication, as users shared the same collision domain and, hence, vied for the same bandwidth.
It functions by abstracting security policies away from hardware terms, such as ever-changing IP addresses, collision domains, or other topological requirements.
lt;p>Devin Akin, CTO at Wi-Fi training and certification company CWNP, recommends appropriately spacing out APs on the same channel to create multiple collision domains so that the aggregate system bandwidth shared by users remains abundant.
Since both ends of the link can be configured to full duplex, worrying about the collision domains is not necessary, and 10/100 media converters are not needed, unless network administrators see the possibility of downgrading the link speed to 10 Mbps.
