FUNDAMENTALS OF COMPUTER

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: -Network gateways are tasked with linking networks by performing translation between different protocols and data formats at the network boundary. Companies may deploy gateways to connect the corporate LAN to the public Internet or to link different internal networks, such as IT and OT networks.

Detailed explanation-3: -A gateway is a connecting device (node) that can connect two networks that employ different transmission protocols. A piece of hardware responsible for accepting, analyzing, and transmitting data packets to other networks. Transmit traffic from one network to another.

Detailed explanation-4: -A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
