The document explains that the internet is a vast network of interconnected computers used for rapid data exchange globally. It outlines key components such as electronic mail, social networking services, e-commerce, and the World Wide Web, describing how these elements facilitate communication and commerce. Tim Berners-Lee is credited with inventing the World Wide Web, which is built upon the Domain Name System.
