What is one of the key benefits of the Internet of Things?

Increased connectivity between physical devices is one of the key benefits of the Internet of Things (IoT). IoT enables a network of interconnected devices to communicate and share data, creating a more cohesive and efficient ecosystem. This connectivity allows devices to work together in ways that enhance automation, improve efficiency, and enable smarter decision-making processes. For instance, smart home devices can interact with one another to optimize energy consumption and improve user convenience, while industrial IoT applications can streamline operations by connecting machinery and tracking performance in real-time.

While the other options touch on relevant aspects of technology, they do not capture the core essence of IoT as effectively. Security risks, manual data entry, and privacy concerns are significant issues associated with IoT, but they do not reflect its primary advantage, which lies in the ability to interconnect a variety of devices for better functionality and information exchange.
