Which term describes the capability of connecting devices to the Internet?

• A. Connectivity
• B. Intelligence
• C. Dynamic Nature
• D. Enormous Scale

Answer: (A)

The main concept here is connectivity—the ability for devices to establish and maintain communication with networks, including the Internet. In IoT, connectivity is what lets sensors and actuators come online, share data, and be controlled remotely. It encompasses the different ways devices can connect (Wi‑Fi, cellular, Bluetooth, LPWAN, etc.) and the reliability of those links. Without connectivity, data can’t flow or commands can’t be delivered, so nothing else in the system can function.

Intelligence is about processing data and making decisions; Dynamic Nature describes how data or states change over time; Enormous Scale refers to the large number of devices involved. These aspects matter, but they depend on connectivity to exist in the first place.
