What's different between gateway and router

Postby chicagotech » Thu Sep 07, 2017 3:44 pm

Both gateway and router are used to regulate network traffic between two or more separate networks. The main different between gateway and router are gateways regulate traffic between two dissimilar networks, while routers regulate traffic between similar networks. The easiest way to illustrate this point is through an example. Routers can be used to segment traffic on corporate networks. This feature is useful on really big networks when you need to reduce the amount of traffic flowing across the network. You can use a router to divide the network into segments and thus allow only traffic that’s specifically intended for a different segment to flow across the router.

A gateway, on the other hand, joins dissimilar systems. Although a gateway can be used to reduce network traffic, it’s more often used to make communication possible in dissimilar environments.
