Different levels of work	OSI Layer 1 Physical Layer	Layer 2 of OSI. The link layer switch uses the physical address or MAC address to determine the destination address for data forwarding.	Layer 3 of OSI, the network-layer router determines the data forwarding address using the idnumber (IP address) of different networks. The router can make more intelligent forwarding decisions.
Work Mode	Broadcast mode. You can just drop it to every port.	Unicast does not affect other ports.
Bandwidth	Shared bandwidth (10/4)	Shared bandwidth (10*4)
	Half duplex.	Full Duplex
		Smart hub, automatic addressing, switching, and processing
		Only conflicting domains can be separated, and broadcast domains cannot be separated.	Split broadcast domains
