What does HTTP stand for?

The correct answer is commonly known to stand for "Hypertext Transfer Protocol." This is the foundation of data communication on the World Wide Web. The protocol outlines how messages are formatted and transmitted, and how web servers and browsers should respond to various commands.

Each component of the term adds meaning: "Hypertext" refers to the way in which documents are linked together (for example, through hyperlinks), "Transfer" indicates the action of moving data, and "Protocol" signifies a set of rules guiding interactions between web clients and servers.

This understanding is critical in web development, as it informs how developers structure their web applications and the fundamental operations of data retrieval and presentation on the Internet.

Other choices do not accurately describe the protocol in question, as they either misstate the terminology or combine terms incorrectly.
