Question

Arrange the following steps in sequence to transmit a message over the internet.
(A) The message is displayed on a web page
(B) Packets are reassembled at the destination
(C) The message is disassembled as packets
(D) Packets are transmitted over the network
Choose the correct answer from the options given below:

• A. (A), (B), (C), (D)
• B. (A), (C), (B), (D)
• C. (B), (A), (D), (C)
• D. (C), (D), (B), (A)

Hint:

Break into packets, send, reassemble, display: C, D, B, A.

Answer 1

The Correct Option is D

Step 1: Idea:
We find the first step and the last step, then check the middle.

Step 2: Find the first step.
Packets must be made before anything else happens. So (C) is first.

Step 3: Find the last step.
The user sees the message only after it is complete. So (A) is last.

Step 4: Order the middle steps.
Packets travel first, (D), and are then put together, (B). The full order is C, D, B, A, which is only in option 4.

Step 5: Test every option against the result.
Option 1: It puts display first, which is impossible, so it fails.
Option 2: It also puts display first, so it fails.
Option 3: It puts reassembly first, when no packets exist yet, so it fails.
Option 4: It follows break, send, rebuild, show, so it fits.

Step 6: Conclusion.
Option 4 is correct. \[ \boxed{(C),(D),(B),(A)} \]
