Computer Networks - Physical and Data Link Layer
Why must the physical layer limit its function to transmitting raw bits without interpreting or processing the data?
Why must the physical layer limit its function to transmitting raw bits without interpreting or processing the data?
hard📝 Conceptual Q10 of 15
Step-by-Step Solution
Solution:
Step 1: Understand physical layer's scope
The physical layer provides a hardware-level interface that transmits raw bits over physical media.Step 2: Recognize separation of concerns
Interpreting, encrypting, or routing data is handled by higher layers to maintain modularity and standardization.Final Answer:
To provide a standardized, hardware-level interface for bit transmission -> Option AQuick Check:
Physical layer focuses on hardware transmission only [OK]
Quick Trick: Physical layer focuses on hardware transmission only [OK]
Common Mistakes:
MISTAKES- Assuming physical layer interprets or modifies data
- Confusing physical layer with network or transport layers
- Believing physical layer handles encryption or routing
