The Function Of The Router

The most important function of the router is to realize the transmission of information. In fact, to put it simply, it is like a courier company to send mail. The mail does not arrive at the final destination instantly, but through the sorting of different substations, constantly approaching the final address, so as to realize the delivery process of the mail. Because routers are between different networks, they are not necessarily the final receiving address of the information. So in the router, there is usually a routing table. Depending on the final address of the information transmitted by the transmitting website, look for the next forwarding address, which network should be. Therefore, we call this process the addressing process. The router addressing process is similar. The final address is matched in the routing table, and the next forwarding address is determined by the algorithm. This address may be intermediate or final arrival.
