This article will explain in detail the differences between routers and light cats. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. Physical structure

Cats generally have two interfaces, a telephone line and a network cable, which can be used by a computer to surf the Internet.

Routers usually have several interfaces, blue interfaces to the home network cable, and other yellow interfaces to several computers at the same time, so that multiple computers can surf the Internet at the same time.

two。 The layers of the OSI model are different.

As shown in the following figure, the OSI model has seven layers, and the cat only converts analog signals to 0,1 digital signals, and does not involve finding paths, so it is in the first physical layer. The router is located in the third network layer to provide routing algorithms and to achieve the function of packet forwarding.

For example, our ping Baidu server, in the middle of a lot of routers, the router stores a routing control table, recording the next step of the data to be sent to that router.
