Which IoT component preprocesses the data generated by sensors before sending it to the cloud, reducing the amount of data forwarded?

• A. Edge
• B. Mobile
• C. Gateway
• D. Cloud Platform

Answer: (C)

Preprocessing data at the boundary between sensors and the cloud is a job for a gateway. The gateway sits between local devices and cloud services, collecting raw sensor readings and applying filtering, aggregation, and compression to reduce the amount of data that needs to be sent forward. This lowers bandwidth usage, reduces latency, and makes cloud ingestion more efficient. Edge devices can perform similar local processing, but the gateway’s role is specifically to bridge local networks with cloud platforms and to trim data before it leaves the local site. A cloud platform handles data after it arrives, and a mobile device isn’t typically responsible for this boundary preprocessing.
