Question

Arrange the following steps in working of a dynamic web page:
A. HTTP response
B. An Application program handles HTTP requests
C. The program executes and produces HTML output
D. HTTP request

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

Hint:

Every web interaction begins with a client "Request" (D) and ends with a server "Response" (A).
This simple paradigm immediately narrows down the options to those ending with A.

Answer 1

The Correct Option is D

•

Step 1: Understanding the Question:
The question asks us to order the steps detailing how a web server processes and renders a dynamic web page to a client in response to their action.

•

Step 2: Key Formula or Approach:
Dynamic web page creation follows a standard client-server request-response lifecycle:
1. Client initiates the interaction by sending a request.
2. Server handles the request and runs server-side scripts or database queries.
3. The server program generates a raw HTML document dynamically.
4. The server packs this HTML and transmits it back as a response.

Step 3: Detailed Explanation:
Let us arrange the given steps chronologically:
- First step (D - HTTP request): The client browser requests a page by sending an HTTP request across the internet to the server.
- Second step (B - An Application program handles HTTP requests): The web server receives the request and forwards it to an application program (like Python, PHP, or Java) to process the logical request.
- Third step (C - The program executes and produces HTML output): The application program executes business logic, fetches database records if required, and generates the resulting HTML markup.
- Fourth step (A - HTTP response): The web server wraps this dynamic HTML inside an HTTP response and sends it back to the client's browser.
Thus, the correct logical order is D $\rightarrow$ B $\rightarrow$ C $\rightarrow$ A.
This corresponds to option (D).

Step 4: Final Answer:
The correct order is given by option (D).
