Show answer & explanation
Correct answer: C
Concept
An IoT system is defined by connected physical objects that sense, exchange, and act on data.
Connectivity may be local—such as Bluetooth, Zigbee, or a private LAN—and an Internet link is required only for services that communicate beyond that local system.
Application
An IoT setup can therefore perform local sensing, automation, and control without Internet access. Internet connectivity becomes necessary only when the design requires cloud services or remote access.
Contrast
UTP is one wired transmission medium; IoT devices may also use wireless or other wired links.
Remote monitoring and control are common IoT capabilities when a suitable network path is available.
Smartphones can serve as interfaces, gateways, or connected devices in an IoT setup.
Result
Thus, the correct statement is: Internet connectivity is not essential for an IoT setup to function.
