Internet of Things (IoT) Practice Exam 2026 – Comprehensive Prep Resource

The role of a gateway in IoT primarily revolves around connecting various devices to the cloud, making it essential for seamless communication in an IoT ecosystem. Gateways serve as intermediaries between local devices and cloud resources, ensuring that data from different devices can be aggregated, translated, and transmitted to the cloud for further processing or analysis. This connectivity is crucial as it enables devices with different protocols or standards to communicate effectively.

Additionally, gateways often perform functions such as protocol translation, data filtering, and sometimes even real-time processing, enhancing the efficiency and performance of IoT networks. By facilitating this connection and enabling devices to send their data to cloud applications or services, gateways are pivotal for the functionality of IoT systems. Their ability to bridge the gap between the edge devices and cloud infrastructure underlines their importance in the overall architecture of IoT solutions.
