Same question on ITPEC: Nov 2021 Q100
Which of the following is the most appropriate as a use case of IoT?
Explanation
Remotely monitoring electricity generation facilities over the Internet — physical equipment sending its status over the network, an IoT use case.
IoT (Internet of Things) gives physical objects, here generators, turbines or solar panels, sensors and a network connection. Their operating data is collected over the Internet and analysed, so operators can manage performance, notice faults early and plan maintenance and repair without being on site.
Answer (d)
Why not others:
- •(a) — making one's profile public to expand one's network is an SNS; it connects people, not things
- •(b) — showing advertisements for similar products after a search is recommendation or targeted advertising on an online store, based on browsing data
- •(c) — recording lectures in advance and distributing them online is e-learning or video on demand
Key rule: An application is IoT when sensors on physical objects send data over a network so that the objects can be monitored or controlled.
