Which statement describes the difference between normal devices and IoT devices?

• A. Connected devices communicate between devices
• B. IoT includes people, things, and software systems
• C. Both A and B
• D. Neither

Answer: (C)

The key idea is that IoT devices are part of an interconnected ecosystem, not just standalone gadgets. One statement highlights that connected devices communicate with one another, which is a core feature of IoT—data flows between devices and often to software platforms. The other statement emphasizes that IoT includes people, things, and software systems, showing that the ecosystem isn’t limited to devices alone but includes human users and software that manage or respond to data. Together, these ideas describe the difference: IoT devices are designed to connect, share data, and work within a broader system that includes people and software. That’s why selecting both aspects best captures what sets IoT apart from normal devices.
