The Internet of Things (IoT) is defined as?

• A. A network of physical objects embedded with sensors, software, and other technologies that enable them to collect and exchange data.
• B. A social media platform for sharing weather data.
• C. A cloud storage service for library media.
• D. A library management system using RFID only.

Answer: (A)

The main idea here is a network of physical objects that are built with sensors, software, and other technologies so they can collect data and talk to each other or to central systems over the internet. This connectivity and data exchange among everyday objects is what makes the Internet of Things possible. Think of devices like smart thermostats, wearable fitness trackers, or sensors on library shelves that monitor temperature, humidity, and stock levels, all sending data to apps or cloud services for monitoring, analysis, and sometimes automated actions.

That’s what sets it apart from the other descriptions. A social media platform for sharing weather data isn’t about connected objects exchanging data; it’s about people sharing information on a platform. A cloud storage service for library media focuses on storing files, not on devices collecting and communicating data from the real world. A library management system using RFID only describes tagging and managing items, but without the broader, interconnected network of devices that continuously collect and exchange data across systems.
