Application of Ethernet
Ethernet switches are most commonly used, and they are cheaper and more complete. Therefore, the application field is very extensive, and they can be seen on large and small local area networks. Ethernet switches usually have several to several tens of ports, essentially a multi-port bridge. In addition, its port rate can be different, work methods can also be different, such as can provide 10M, 100M bandwidth, provide half-duplex, full-duplex, adaptive work methods.
1. Each port of an Ethernet switch is directly connected to the host and generally works in full-duplex mode.
2. The switch can connect many pairs of ports at the same time, so that each pair of hosts communicating with each other can transmit data without conflict like the exclusive communication media.
3. The bandwidth of the shared transmission media. For a common 10 Mb/s shared Ethernet network, if there are N users in total, the average bandwidth occupied by each user is only one-Nth of the total bandwidth (10 Mb/s).
