Explanation
Gateways are an essential component of an IoT architecture, providing the connection between user devices and the network. Gateways act as a bridge between the device layer and the cloud layer, enabling the remote monitoring and control of user devices. Gateways also provide security features such as data encryption and authentication, which helps protect user data. Additionally, gateways provide additional features, such as data aggregation and protocol conversion, which can help increase the efficiency of the overall IoT architecture.
