A gateway is a network node that serves as an entry and exit point for a network connecting two networks with different sets of protocols, as well as converting one protocol into the other.
Difference between gateway and router
|A device that acts as a gate and connects two networks having different sets of protocols.||A networking device that manages and forwards data packets to computer networks.|
|The main principle of a gateway is to convert one protocol to the other.||The main principle of the router is to route traffic from one network to another with the best route.|
|A gateway acts as a connection between two dissimilar networks.||A router transports data packets over similar networks.|
|A gateway does not support dynamic routing.||A router supports dynamic routing.|
|A gateway can operate until layer 5 of the OSI model.||A router can operate only on layer 3 and layer 4 of the OSI model.|
