Which protocol manages transactions between a web server and a client computer when visiting a web page?

The correct answer is HTTP, which stands for Hypertext Transfer Protocol. This protocol is specifically designed for transferring documents, particularly web pages, from a web server to a client, typically a browser. When a client requests a web page, it does so using HTTP, which handles the request and response process that allows the user to retrieve and view content on the internet.

HTTP defines how messages are formatted and transmitted, and it also specifies how web servers and browsers should respond to various commands. Its primary role is to transmit hypertext, which is structured text that uses hyperlinks to secondary text, enabling users to navigate through the vast resources available on the web.

While TCP (Transmission Control Protocol) is critical for establishing reliable connections and ensuring the parts of the data packets reach their destination without errors or loss, it is not specifically responsible for web transactions. Similarly, IP (Internet Protocol) is related to addressing and routing packets of data but does not manage the content of those packets. FTP (File Transfer Protocol), on the other hand, is designed for transferring files rather than handling web pages, making it unsuitable for managing web transactions.
