Correct Answer:
B. Cloud processes data on centralized servers; edge processes data near the source.
Explanation:
The correct answer is Cloud processes data on centralized servers; edge processes data near the source. because it accurately reflects the architectural differences in data processing locations.
- Step 1 (Centralized Architecture): Cloud computing relies on massive, geographically centralized data centers to process, store, and manage global consumer data over the internet.
- Step 2 (Decentralized Local Architecture): Edge computing brings computation and storage directly to local hardware nodes or IoT devices, processing data immediately where it is gathered to reduce latency.
- Incorrect Options:
- Cloud computing is older; edge is newer is incorrect because age is an arbitrary timeline detail rather than the core architectural distinction between them.
- Cloud is local; edge is global is incorrect because it reverses reality; cloud resources span global networks while edge environments focus on local proximity.
- Cloud uses cables; edge is entirely wireless is incorrect because both frameworks utilize combinations of fiber optic wiring and wireless communication layers.
