ITPEC FE Morning April 2022 Question 70
ITPEC FE Morning April 2022 — Question 70 of 80
IoT systems follow a four-stage data flow: collection → transmission → analysis → utilization.
Each stage maps to a specific type of tool:
- •Data collection (A): Temperature sensor — physical sensors gather raw data from equipment
- •Data transmission (B): Wireless communication — networks carry data to processing systems
- •Data analysis (C): Abnormal value judgment tool — software detects anomalies in data
- •Data utilization (D): Display for work instructions — results are acted upon by workers
Why not others:
- (a) Abnormal value judgment is analysis, not collection — it requires data to already exist
- (b) Display for work instructions is the final output stage (utilization), not collection
- (d) Wireless communication transmits data — it comes after collection, not during it
Key rule: IoT pipeline = Sense → Send → Analyze → Act. Match each device to its stage.
