Are you confused if I need a switch or router for the wireless network? Don't worry, here we tell you the 5 difference between switch and router.
Easy-to-understand comparison: Switches vs Routers
The router can automatically assign IP to your LAN, virtual dialing, like a traffic policeman, directing your computer where to go, you don't have to worry about it. The switch is only used to distribute network data.
The router is at the network layer, the router is addressed according to the IP address, the router can handle the TCP/IP protocol, and the switch cannot.
The switch is at the relay layer and the switch is addressed based on the MAC address.
A router can assign an IP to a number of hosts, and these hosts only show one IP to the outside. The switch can connect many hosts, each of which has its own IP.
The router provides the service of the firewall, which is not available to the switch.
Hubs and switches are all port extensions, which are to expand the access point of the LAN (usually Ethernet), which allows the LAN to connect to more computers. Routers are used to connect between networks, that is, to connect to different networks.
For example, the router is equivalent to the post office, the letter is delivered to the recipient address, and its task is completed. But the letter has arrived at your dormitory, and this address is not exclusive to you alone, so the uncle Wang is also responsible for giving the letter to you, he will not care about the address of the recipient, only the name of the recipient Then make an inside call and ask you to get the letter.
If you don't have a post office, you can't send letters to beautiful girls around the world, and you can't receive letters from beautiful girls outside the building. However, because of the existence of the uncle Wang, you can still communicate with him through the good friends of the same dormitory.
The system consisting of all post offices is the "wide area network", and your dormitory building is the "local area network". The construction of the local area network does not require a router.
