Which of the following statements is correct about the Internet of Things (IoT), which can create a smart environment by having an interconnected network of hardware devices, sensors, connectivity and required software?
AEvery IoT device or item must be connected using UTP cables
BIoT environments cannot be monitored and controlled remotely
CInternet connectivity is not essential for an IoT setup to function ✓ Correct
DModern smart mobile phones cannot be connected to an IoT setup
Correct answer: (C) Internet connectivity is not essential for an IoT setup to function
Explanation
An IoT setup can work over local links such as Bluetooth or a home network, so internet connectivity is not essential for it to function.
The claim that every IoT device must use UTP cables is wrong, since many connect wirelessly.
The claim that IoT cannot be monitored or controlled remotely is wrong, as remote control is a core feature.
The claim that smart mobile phones cannot join an IoT setup is wrong, since phones often act as controllers.
The internet mainly extends IoT reach beyond the local area rather than being strictly required.
IoT links sensors, devices and software so they can share data and act on it.
