The Internet is a global network connecting millions of computers and over 100 countries. No single entity owns or controls the entire Internet. The World Wide Web is a system of interlinked hypertext documents accessed via the Internet using a web browser. URLs contain a protocol identifier and resource name to specify the location of a resource. IP addresses and domain names are used to identify and route messages to computers on the Internet. While the Internet provides a wealth of information and opportunities for connection, it also enables risks like misinformation, addiction, privacy concerns, and criminal behavior.
