What are IoT Operating Systems?

IoT operating systems (OS) are specialized software platforms designed to run on Internet of Things (IoT) devices, providing the necessary functionality for resource management, communication, and real-time processing. These operating systems are optimized for low power consumption, small memory footprints, and efficient processing, allowing IoT devices to operate in environments with limited resources. IoT operating systems typically offer features like device control, sensor management, connectivity protocols, and security to ensure that IoT devices perform reliably and securely. They are used in a variety of IoT applications, such as smart home devices, wearables, industrial machinery, and automotive systems.
