Ethnernet bus is a common LAN technology and its main features include:

1, fast speed: Ethernet bus speed is usually in the 10Mbps, 100Mbps, 1Gps and other levels, can meet the needs of most local area networks

2, distance limitation: Ethernet bus transmission distance is restricted, generally no more than 100 meters, and with the increase in transmission rate, the distance limitation will be more strict

3、Broadcast transmission: Ethernet bus adopts broadcast transmission, all nodes can receive the same packet, which needs to be filtered by MAC address.

4、Conflict detection: Ethernet bus using CSMA/CD protocol, can be packet conflicts, and retransmission, thus ensuring reliable data transmission

5, easy to install and maintain: Ethernet bus hardware equipment is relatively simple, easy to install and maintain, but also has a high compatibility and scalability of the teachings
