The document discusses the CSMA/CD access method used in Ethernet networks, noting that increased computers on a LAN lead to higher collision risks and potential retransmission delays. It highlights that Ethernet is best suited for low traffic networks. Additionally, it summarizes various standard Ethernet cable implementations.

1. 1
Access Method - CSMA/CD
• Carrier Sense Multiple Access / Collision Detection,More computers on the
LAN, higher chance of collisions,Retransmission may result in collision
again and cause further delay
As the result, the network becomes standstill,Hence, Ethernet is suitable for
low traffic networks
Check the line
If no packet,
OK to transmit
