IoT network power usage: which statement is true?

• A. They rely solely on high power energy.
• B. They use either low power energy or high power energy.
• C. They rely solely on low power energy.
• D. They use neither.

Answer: (B)

In IoT, power needs vary a lot depending on the device’s role. Many sensors are designed to sip energy, staying mostly dormant and waking only briefly to sense or transmit, which makes them low-power by design. But other components—such as cameras, edge processors, gateways, or devices with continuous connectivity—require more energy to operate reliably. Because of this range, it’s accurate to say IoT networks use either low power energy or high power energy, depending on the specific device and its tasks. The idea that all devices are solely high power or solely low power doesn’t fit the real variety, and it’s not correct to say energy isn’t used at all.
