Why Gateway and Router are not one ?

1 Answer

Answer :

Routing is the process of sending data from one network to another. The device used for routing is called a router. This device is used to connect different networks. It works on three types of networks : LAN, MAN, and WAN . Gateways, on the other hand, are used to connect different types of networks. Router devices do not facilitate protocol translation , but they do facilitate gateways. It works on protocol translation when connected to different networks. So router and gateway are not one.
