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.
The 100/100 Bridge is the industry's first product which allows users to bridge two 100 Mbps segments and extend their Fast Ethernet network beyond the collision domain limitation of 205 meters.
The NuHub, which offers 8 100Base-TX ports, can also be connected to another 100Base-TX switch to provide a maximum of 16 100Base-T ports on the same collision domain at a very cost-effective price-per-port.
This represents a total of 358 ports and the largest Fast Ethernet collision domain on the market.
It also is easily combined with Asante's other Fast Ethernet hub, the AsanteFAST 100 TX Hub, for a total of 30 AsanteFAST hubs possible in a single Fast Ethernet collision domain -- the largest on the market.
Delivering a range of features and functionality that provide companies with an easy migration path to 100BASE-TX networking and speeds 10 times faster than standard 10BASE-T Ethernet, the AsanteFAST 100 Hub offers support for multiple computer platforms, NWay(tm) Auto-Negotiation, easy installation, and stackability to 118 ports -- the largest Fast Ethernet collision domain on the market.
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.
