What is a network switch?
A switch is a network device based on MAC that can complete the function of encapsulating and forwarding data packets. The switch can "learn" the MAC address and store it in the internal address table. By establishing a temporary switching path between the originator and the target receiver of the data frame, the data frame can directly reach the destination address from the source address. A Network switch is a switch, and its predecessor is a bridge. The switch uses hardware to complete the tasks of filtering, learning, and forwarding processes by using software for bridges in the past. SWITCH is faster than HUB. This is because HUB does not know where the target address is and sends data to all ports. And there is a routing table in SWITCH, if it knows where the target address is, it will send the data to the designated place, if it doesn't know, it will send it to all ports. Such filtering can help reduce the data transmission volume of the entire...
