What is an HTTP Response?

• A. A script that runs on a server to generate HTML.
• B. A numbered response from a web server indicating the status of an HTTP request.
• C. A type of password hashing algorithm.
• D. A markup language for formatting emails.

Answer: (B)

An HTTP Response is the message a web server sends back after it receives an HTTP request, indicating what happened with the request and usually providing the requested data. It starts with a status code, a number that shows the outcome (for example, 200 means OK, 404 means Not Found), followed by headers with metadata (like content-type and content-length) and often a body containing the actual content (HTML, JSON, an image, etc.). The key idea is that the numeric status communicates the result of the request, while the rest of the response delivers any data the client needs. The other options describe things that aren’t the response: a script that generates HTML is server-side code, a password hashing algorithm is a security method, and a markup language for emails is unrelated to HTTP responses.
