What best defines the Internet of Things (IoT)?

• A. A cloud storage service
• B. A programming language
• C. The connection of a broad array of physical devices to the internet, enabling data collection and management via software
• D. A hardware encryption device

Answer: (C)

IoT is about linking everyday physical objects to the internet so software can collect data from them and manage or control them remotely. This includes sensors and actuators in devices like smart thermostats, wearables, and industrial equipment, all sending information to applications or cloud services and sometimes receiving commands to act. The defining idea is the networked ecosystem of physical devices becoming data sources and control points, not a cloud storage service, a programming language, or a hardware encryption device. Cloud storage is just where data is kept, a programming language is a tool for building software, and a hardware encryption device is a security device, none of which capture the essence of connecting physical things to enable data-driven software interactions.
