At power companies, the amount of electricity consumed by each household is measured remotely by communicating with electrical meters that are connected to the Internet, instead of measured by meter readings by a person. Which of the following is a term that represents the mechanism where a range of devices are connected to the Internet and utilize information in cases such as this?
Explanation
IoT (Internet of Things) — devices such as electricity meters connected to the Internet so their data can be collected and used.
Smart meters that report each household's consumption over the network are a typical IoT case: physical things with sensors are connected to the Internet, send their data automatically, and the data is analyzed and used, here replacing a person reading the meter.
Answer (b)
Why not others:
- •(a) EDI — standardized exchange of business documents such as orders and invoices between companies
- •(c) ISP — an Internet service provider, a company that provides connections to the Internet
- •(d) RFID — identifies objects by radio tags at short range; it can feed data into an IoT system, but it does not mean connecting devices to the Internet
Key rule: Things connected to the Internet that exchange and use their data are IoT, whatever the device.
