Question

Where does data analysis occur in Edge Computing?

• A. In a centralized data centre
• B. On the public cloud
• C. On the device, locally and in real time
• D. On the Internet

Hint:

In Edge Computing, processing happens at the “edge” of the network (on-device or via local gateway) to achieve near-zero latency, whereas Cloud Computing processes data on centralized, remote server farms.

Answer 1

The Correct Option is C

Step 1: Understanding Edge Computing:
Edge computing is a distributed computing paradigm that brings computation and data storage closer to the physical location where the data is gathered, rather than relying solely on a central server thousands of miles away.

Step 2: Identifying the Benefits of Processing at the “Edge”:
By processing data locally on local edge nodes (such as IoT gateways, local smart devices, or computers):
• Latency is minimized: No round-trip transit delay to cloud data centers.
• Bandwidth is saved: Only processed, critical metadata needs to be sent to the cloud, rather than massive raw data streams.
• Offline availability: The system continues functioning even with intermittent internet access.

Step 3: Verification of Options:
Centralized data centers (A) and Public clouds (B) represent classical centralized architectures, which are the polar opposites of edge computing. Processing “on the Internet” (D) is vague and does not localize the execution to the device. Thus, (C) is the precise definition.
