Detailed explanation-1: -Gateway. Gateway is a network device used to connect two or more dissimilar networks. In networking parlance, networks that use different protocols are dissimilar networks. A gateway usually is a computer with multiple NICs connected to different networks.

Detailed explanation-2: -A gateway mainly works on IP(Internet Protocol) Addresses for dissimilar network communication. It has control over both collisions(inside a network) as well as broadcast(outside the networks) domain. It can also encapsulate and decapsulate the data packets when they send and receive the data packets respectively.

Detailed explanation-3: -Device used to connect dissimilar networks is known as routers, switch, bridge, repeater etc. These are known as network devices and are used to connect different types of networks. 1)Routers:-A router is a device like a switch and is mainly a network layer device and are used to connect LANs and WANs together .

Detailed explanation-4: -Routers are general-purpose devices that interconnect two or more heterogeneous networks. They are usually dedicated to special-purpose computers, with separate input and output network interfaces for each connected network.
