easy📝 Conceptual Q11 of 15
Node.js - Cluster Module
Why does clustering improve performance in Node.js applications?
AIt converts data into text format for easier reading.
BIt deletes unnecessary data to save memory.
CIt creates multiple worker processes to distribute load across CPU cores.
DIt sorts data alphabetically to find items faster.
Step-by-Step Solution
Solution:

  1. Step 1: Understand clustering purpose

    Clustering in Node.js creates multiple worker processes to utilize multiple CPU cores.

  2. Step 2: Link to performance

    By distributing load across workers, it enables parallel request handling, reducing time and improving throughput.

  3. Final Answer:

    It creates multiple worker processes to distribute load across CPU cores. -> Option C

  4. Quick Check:

    Clustering creates workers = better performance [OK]
Quick Trick: Clustering forks workers to use multiple cores [OK]
Common Mistakes:
  • Thinking clustering deletes data
  • Confusing clustering with sorting
  • Assuming clustering changes data format
