ITPEC FE Morning April 2019 Question 71

A computer that works alone without accessing any server — a standalone machine exchanges no data over a network, so it is not IoT.

IoT gives things such as machines, vehicles and meters sensors and a communication function, connects them to the Internet, and collects and uses their data remotely. Option (a) deliberately cuts the computer off from the network and does all the work locally, which is the opposite of that idea.

Answer (a)

Why not others:

• •(b) — construction equipment with built-in sensors reporting its operating status and worn parts to the maker over the Internet is industrial IoT (remote monitoring)
• •(c) — collecting car positions in real time and sharing jam information between vehicles and roadside units is IoT in traffic (connected cars)
• •(d) — an electricity meter that reports usage to the power company by itself is a smart meter, a standard IoT example

Key rule: IoT needs both a sensing or controlled thing and a network connection over which its data is collected; take away the connection and it is just an embedded device.
