Connectivity in computing spans three related terms: the Internet, networks, and the World Wide Web. The Internet is the global system of interconnected networks that uses shared protocols to move data between devices worldwide. Networks are the various groupings of devices—local area networks, wide area networks, and others—that connect devices together and to the Internet, enabling sharing and communication. The World Wide Web is a vast collection of documents and resources accessed through the Internet using web protocols; it's a service built on top of the Internet that makes information easy to access via hyperlinks and browsers. Together, these three describe the full spectrum of how computers connect and interact. The set that includes all three is the best match because it covers the underlying infrastructure, the connection of devices, and the main service used to access information online. The Internet alone misses the local networks, the World Wide Web alone misses the underlying transport, and local area networks by themselves don’t address the global Internet or the Web.
