Related introduction:
The MAC address is a 12-digit hexadecimal number burned into the network card chip by the manufacturer when the network card leaves the factory. It is used for identification. Every network card is the same in the world.
If you have heard of the famous "Network Seven-Layer Model ISO" in the network profession, the physical link network transmission session represents a total of seven layers of applications, forming a complete network framework. MAC works at the second data link layer, and its function is to identify a computer equipped with a network card, that is, a computer working in the network.
Perhaps you know that "IP address is used to identify a host", but in fact, IP address is based on MAC address. On the network, the system cannot recognize the IP address at all. , but through the connection between MAC and IP address, you can find a host you want to access.
When the system is looking for a host in the network, it first uses the IP address to make a broadcast call, and the visited host responds with its own MAC and IP address, so that it knows which machine's IP and MAC are correctly corresponding. Record it in the cache, and it will be possible to access this host directly through the MAC table in the future. The working principle of the switch is exactly like this. The reason why the switch is better than the ordinary HUB is that it can quickly find the host you want to access through the MAC address table.
