ITPEC FE Subject A October 2025 Question 53

Topic: Business IndustryAlso asked in October 2018 and April 2022

Basic elements and examples of devices and services when the IoT is used in a factory’s equipment maintenance tasks are compiled as shown below. When a) through d) correspond to one of A through D, which of the following corresponds to A?

Basic elementExample of device and service
Data collectionA
Data transmissionB
Data analysisC
Data utilizationD

Explanation

Temperature sensor for equipment — data collection is the stage where a device measures the equipment and produces raw data.

An IoT system works in four stages, and each option fits exactly one:

Basic elementExample
Data collection (A)Temperature sensor for equipment
Data transmission (B)Wireless communication within the factory
Data analysis (C)Abnormal value judgment tool
Data utilization (D)Display for work instructions

Answer (c)

Why not others:

  • •(a) — judging whether a value is abnormal works on data already collected: that is C, analysis
  • •(b) — showing instructions to workers acts on the result of the analysis: that is D, utilization
  • •(d) — wireless communication carries data from the sensors to where it is analysed: that is B, transmission

Key rule: Place an IoT component by what it does to the data: sensors collect, networks transmit, software analyses, and displays or actuators use the result.
