What does HTTP stand for in web communication?

The correct answer, Hypertext Transfer Protocol, accurately describes the underlying protocol used for data communication on the World Wide Web. This protocol is fundamental for transferring hypertext documents, which are essential components of the web that allow users to navigate from one page to another through hyperlinks. HTTP facilitates the request-response cycle between clients (such as web browsers) and servers, allowing for the retrieval and display of web content.

The other options do not accurately reflect the established terminology within the field of web communication. "Hypertext Transmission Protocol" and "Hypertext Text Transfer Protocol" suggest incorrect terminology; the phrase "text" is redundant in this context because hypertext inherently refers to text with hyperlinks. "High-level Transfer Protocol" fails to capture the specific purpose and function that HTTP serves in web communications, which relates specifically to hypertext rather than a general transfer of data.
