_____ is a set of rules for transferring files such as text, graphics, images, sounds, and other multimedia files on the World Wide Web.

• A. Hypertext Transfer Protocol (HTTP)
• B. File Transfer Protocol (FTP)
• C. Simple Mail Transfer Protocol (SMTP)
• D. Post Office Protocol (POP3)

Answer: (A)

HTTP governs how a web client (like a browser) requests and a web server sends web resources—text, graphics, images, sounds, and other multimedia—across the World Wide Web. It defines the format of requests and responses, how resources are identified with URLs, and the rules for transferring the data, including status codes that indicate success or errors. This protocol is built for the web’s needs, enabling reliable transfer of diverse content as users browse.

FTP, while also a file-transfer protocol, is meant for moving files between servers or machines rather than serving web resources to a browser. SMTP and POP3 handle email transmission and retrieval, not web resource delivery.
