Ethernet 10BASE-T Overview
The VIP 4E port adapter provides up to four IEEE 802.3 Ethernet
The term Ethernet is commonly used for all carrier sense multiple access/collision detection (CSMA/CD)
Stations on a CSMA/CD LAN can access the network at any time. Before sending data, the station listens to the network to see of it is already in use. If it is, the station waits until the network is not in use, then transmits. A collision occurs when two stations listen for network traffic, hear none, and transmit simultaneously. When this happens, both transmissions are damaged, and the stations must retransmit. The stations detect the collision and use backoff algorithms to determine when they should retransmit.
