Switch is a network device used for electrical signal forwarding. It can provide exclusive electrical signal path for any two network nodes accessing the switch. The most common switch is Ethernet switch. Other common are telephone voice switch, optical fiber switch, etc.

The transmission modes of the switch are full duplex, half duplex, full duplex / half duplex adaptive.

The full duplex of the switch means that the switch can receive data while sending data. The two are carried out synchronously, which is the same as when we call at ordinary times. We can hear each other's voice while talking. Current switches support full duplex. The advantage of full duplex is that the delay is small and the speed is fast.
