What is the Internet of Things (IoT)?

The Internet of Things (IoT) refers to a network of interconnected physical devices that communicate with each other and with centralized systems through the internet. These devices can range from household items, such as smart thermostats and refrigerators, to more complex systems like industrial machines. The key aspect of IoT is the ability for these devices to collect and exchange data without human intervention, enhancing automation and providing users with valuable insights and control over their environments.

IoT enables improved efficiency, convenience, and functionality through connectivity. For instance, smart sensors in a home can adjust heating or lighting based on occupancy, while health monitoring devices can track patients' vital signs and send alerts to medical professionals in real-time. This concept is increasingly important in various sectors, including healthcare, agriculture, smart cities, and industrial automation, indicating its broad utility and transformational potential.

The other options describe different concepts: software for data management pertains to data processing and organization, cloud storage is about saving files online for accessibility from various devices, and a streaming service focuses on delivering media content over the internet. Each serves specific purposes but does not encapsulate the essence of the interconnected network described by the Internet of Things.
