Which protocol is primarily used for delivering web pages to a browser?

• A. Hypertext Transfer Protocol
• B. File Transfer Protocol
• C. Simple Mail Transfer Protocol
• D. Post Office Protocol

Answer: (A)

Web pages are delivered to a browser using the HTTP protocol. HTTP defines how a browser asks for a resource (like an HTML file) and how a server responds with that resource plus metadata such as status codes and headers. This request/response exchange happens every time you load or refresh a page, and it’s designed to be stateless, meaning each request is independent of others. In everyday use, most traffic actually travels over HTTPS, which is HTTP secured with encryption, ensuring data privacy and integrity. The basic mechanism—request a resource, receive the content—remains HTTP, just with added security in practice. Other protocols listed serve different purposes: a file transfer protocol moves files between devices, a protocol for sending emails handles mail transmission, and another retrieves email from a server. So, delivering web pages to a browser is the domain of HTTP.
