easy📝 Factual Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Identify physical layer tasks
The physical layer converts digital bits into electrical, optical, or radio signals to send over the medium.Step 2: Exclude unrelated functions
Compression, IP addressing, and session management belong to higher layers, not the physical layer.Final Answer:
It converts bits into signals for transmission -> Option DQuick Check:
Physical layer = bit-to-signal conversion [OK]
Quick Trick: Physical layer changes bits to signals, not data compression [OK]
Common Mistakes:
MISTAKES- Confusing physical layer with data link or network layers
- Thinking physical layer compresses or manages IP
- Mixing session management with physical layer
