A gateway is a device or software system that connects two different networks, systems, or communication environments and allows them to exchange information. It acts as an entry and exit point, receiving data from one side and forwarding it to another. A gateway can also translate between different communication methods or protocols when connected systems cannot communicate directly.
Gateways are widely used in computer networks, cloud services, Internet of Things devices, and enterprise systems. For example, a gateway can connect a local network to the internet or allow sensors using different communication technologies to exchange data with a central platform. By managing communication between separate environments, gateways help control data flow, improve compatibility, and provide an organized connection between otherwise independent systems.
