Which one of the following statements is FALSE?

Correct answer: "HTTP describes the structure of web pages" is FALSE.

• "HTTP runs over TCP" — This is correct. HTTP is an application-layer protocol that typically uses TCP (e.g., ports 80 and 443). Note: HTTP/3 is an exception and runs over QUIC (which uses UDP).

• "HTTP describes the structure of web pages" — This is false. The structure and semantics of web pages are defined by HTML (and styled with CSS). HTTP's role is to transfer those resources between client and server.

• "HTTP allows information to be stored in a URL" — Effectively true: URLs can contain path segments and query parameters (for example, ?key=value) that carry information to the server, and HTTP requests use those URLs to request resources.

• "HTTP can be used to test the validity of a hypertext link" — True. Sending an HTTP HEAD or GET request and checking the response status code (e.g., 200 vs. 404) lets you verify whether a link points to a valid resource.
