medium📝 Analysis Q7 of 15
Step-by-Step Solution
Solution:
Step 1: Review physical layer capabilities
The physical layer transmits raw bits but does not detect or correct errors.Step 2: Identify correct error handling layers
Error detection and correction are handled by data link or higher layers.Final Answer:
Error detection and correction are done by higher layers, not physical -> Option CQuick Check:
Physical layer transmits bits, no error correction [OK]
Quick Trick: Error handling is above physical layer [OK]
Common Mistakes:
MISTAKES- Attributing error correction to physical layer
- Confusing physical layer with data link layer
- Assuming physical layer manages IP or compression
