A gateway is a node  considered as the entrance point to other networks, so that different networks can communicate with each other. It connects different network follows different protocols and different properties. Gateway can be any software, hardware or combination of both. Gateway can acts as a proxy server or firewall.

A bridge is hardware networking device used to build communication among different computer network (LANs) that follows same protocols. Bridge helps in increasing network capacity by joining multiple networks. Bridge is more intelligent device as it knows which computer is part of which side and so allow those messages to get to the other side

A router is a hardware networking device that connects multiple physical networks that follows different protocols. A router is responsible for receiving, analyzing and moving incoming data packets to another network. A router ensures that packets are travelling the most efficient paths to their destinations based on data properties. A router is best suitable for
