Gateway

A gateway is a networking device that connects two or more networks, allowing data to flow between them. It acts as an interface between different communication protocols, facilitating communication between devices on disparate networks. Gateways play a crucial role in routing data, managing network traffic, and enforcing security policies in complex network environments.

Think of a Gateway as a digital bridge. Just as a bridge connects two separate landmasses, a gateway links different networks together, enabling data to flow between them.
