Computer Networks - Physical and Data Link Layer
If a physical layer device sends the bit sequence 1010 as electrical signals, what is the main output at the receiving end?
If a physical layer device sends the bit sequence 1010 as electrical signals, what is the main output at the receiving end?
medium📝 Analysis Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Trace physical layer transmission
The physical layer sends raw bits as signals; the receiver recovers the same bit sequence.Step 2: Understand data interpretation
Interpreting the bits into messages or compressing/encrypting happens at higher layers, not physical.Final Answer:
The exact bit sequence 1010 -> Option DQuick Check:
Physical layer output = raw bits [OK]
Quick Trick: Physical layer output is raw bits, not messages [OK]
Common Mistakes:
MISTAKES- Expecting physical layer to decode messages
- Confusing compression or encryption with physical layer output
- Assuming physical layer changes bit content
