Which of the following networks operates on top of the Internet?

The world wide web operates on top of the Internet by utilizing the underlying infrastructure to transmit data using the Hypertext Transfer Protocol (HTTP) and the Transmission Control Protocol (TCP). It consists of a vast number of interlinked hypertext documents, accessible via web browsers and made available through servers connected to the Internet. This relationship allows users to navigate from one page to another through hyperlinks, providing a seamless experience on a global scale.

While local area networks (LANs), intranets, and private networks may utilize the Internet for connectivity, they are generally considered separate systems that often serve more localized or specific purposes. Local area networks are typically confined to a small geographic area, such as a building or campus, while intranets are private networks designed to facilitate communication and information sharing within an organization. Private networks, in general, offer restricted access and may include both local and wide area networks that do not connect directly to the public Internet. Thus, the answer specifically identifies the world wide web as the network that explicitly operates over the Internet itself, utilizing its global structure to connect content and users.
