WWW uses ____ protocol.

The correct answer is option 'E' (None of these).

Explanation:

World Wide Web (WWW) is a system of interlinked hypertext documents that are accessed through the Internet. It is commonly referred to as the Web. When we access a website, we use a web browser (such as Google Chrome, Mozilla Firefox, or Internet Explorer) to communicate with the server where the website is hosted. This communication between the web browser and the server is facilitated by various protocols.

Protocols are a set of rules and procedures that govern the transmission of data over a network. Different protocols are used for different purposes. While the options provided in the question are commonly used protocols, none of them specifically represent the protocol used by the World Wide Web.

The protocol used by the World Wide Web is called Hypertext Transfer Protocol (HTTP).

HTTP (Hypertext Transfer Protocol) is an application protocol that allows for the transfer of hypertext, which includes links, images, and other media, over the Internet. It defines how messages are formatted and transmitted, as well as the actions that web servers and browsers should take in response to various commands.

HTTP operates on top of another protocol called the Transmission Control Protocol (TCP). TCP ensures reliable and ordered delivery of data packets over the Internet.

Key Points:
- The World Wide Web (WWW) is a system of interlinked hypertext documents accessed through the Internet.
- Various protocols are used for communication between web browsers and servers.
- The protocol specifically used by the World Wide Web is Hypertext Transfer Protocol (HTTP).
- HTTP operates on top of the Transmission Control Protocol (TCP) for reliable data transmission.
- The options provided in the question (FTP, SMTP, Telnet) are not the protocols used by the World Wide Web.

Therefore, the correct answer is option 'E' (None of these).
