Question

Arrange these protocols in the order of TCP/IP stack from lowest to highest layer: 
A. HTTP 
B. TCP 
C. IP 
D. MAC Address

• A. D, C, B, A
• B. D, C, A, B
• C. C, D, A, B
• D. C, D, B, A

Hint:

Stack: MAC → IP → TCP → HTTP (bottom to top).

Answer 1

The Correct Option is A

Concept: TCP/IP layers (bottom to top):
• Link layer (MAC)
• Internet layer (IP)
• Transport layer (TCP)
• Application layer (HTTP) Step-by-step order: \[ \text{MAC} \rightarrow \text{IP} \rightarrow \text{TCP} \rightarrow \text{HTTP} \] \[ D \rightarrow C \rightarrow B \rightarrow A \] \[ \therefore \text{Correct answer is (A)} \]
