What are the advantages of switched Ethernet over traditional Ethernet?

No need to change the network hardware; can be converted between high-speed and low-speed networks.

1, switched Ethernet does not need to change the network hardware; switched Ethernet can be converted between high-speed and low-speed networks, to achieve cooperation between different networks.

2. Traditional Ethernet requires changes to the network hardware; traditional Ethernet can not be converted between high-speed and low-speed networks to achieve synergy between different networks.
