Which statement best defines the Internet of Things?

• A. Cloud-based virtual machines
• B. Physical Devices that collect and share data
• C. High-speed networks between servers
• D. Artificial intelligence in devices

Answer: (B)

Physical devices with sensors and connectivity that collect data from the real world and share it over a network are the essence of the Internet of Things. These devices—from smart home gadgets to industrial sensors—turn everyday objects into data-enabled systems, providing real-time measurements and, often, the ability to be controlled remotely. This makes automation and data-driven decisions possible. The other ideas describe computing infrastructure, networking between servers, or embedded intelligence, but they don’t define IoT itself. IoT is defined by the objects that sense the world and communicate that data.
