Computer Networks - OSI and TCP/IP Models
A network uses a layered model where Layer 2 handles framing and Layer 3 handles addressing. What happens if Layer 2 is changed but Layer 3 remains the same?

medium📝 Analysis Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Recall independence of layers
Layer 2 and Layer 3 perform different tasks and communicate via defined interfaces.Step 2: Analyze effect of changing Layer 2
Changing framing in Layer 2 does not affect addressing in Layer 3 if interfaces remain consistent.Final Answer:
Addressing still works because layers are independent -> Option CQuick Check:
Layer independence = Function continues [OK]
Quick Trick: Change one layer, others keep working if interfaces stable [OK]
Common Mistakes:
MISTAKES- Believing layers must change together
- Thinking Layer 3 depends directly on Layer 2 internals
