medium📝 Analysis Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Identify physical layer functions
The physical layer transmits raw bits as signals without decoding or interpreting them.Step 2: Recognize decoding is done at higher layers
Decoding and extracting meaning happen at higher layers like the data link or application layer.Final Answer:
The physical layer only transmits bits and does not interpret their meaning -> Option AQuick Check:
Physical layer transmits bits, no decoding [OK]
Quick Trick: Physical layer transmits bits, no decoding [OK]
Common Mistakes:
MISTAKES- Thinking physical layer interprets or decodes data
- Confusing physical layer with data link or network layers
- Assuming physical layer performs encryption or error correction
