Gateway

A gateway is a network device or software application that serves as an intermediary or bridge between two or more different networks, enabling them to communicate and exchange data. Gateways play a crucial role in facilitating communication between networks with different protocols, architectures, or technologies, ensuring that data can flow smoothly and securely from one network to another. It includes characteristics like Protocol transmission, Interconnection, Security, Data routing, Network management, integration, Cloud connectivity and application layer services. Gateways are used in a wide range of networking scenarios, including in homes and businesses to connect to the internet, in industrial settings to link different machines and sensors, and in the IoT to facilitate communication between devices and cloud platforms. They are essential for ensuring that data can flow seamlessly between diverse networks, regardless of their underlying technologies or configurations.
