Which definition best describes the Internet of Things (IoT)?

• A. A cloud storage service
• B. Interconnected network of home and industrial devices that collect data and communicate over the internet
• C. A type of database
• D. A wireless protocol for smartphones

Answer: (B)

At heart, the Internet of Things is about physical devices that are equipped with sensors, software, and connectivity to collect data and talk to each other over the internet. It isn’t just one device or a place to store data; it’s a network of many devices—like smart thermostats, wearables, or industrial sensors—that can be monitored, controlled, or automated remotely. This interconnected data exchange across diverse devices is what enables automation, remote monitoring, and smarter decisions in both homes and industries. The other options describe a storage service, a database, or a single wireless protocol, which don’t capture the idea of a broad network of devices communicating and sharing data.
