4. Apa di Internet? Web definitions for Internet The Internet (also known simply as the Net) is the worldwide, publicly accessible system of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP). It consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail , online chat , and the interlinked Web pages and other documents of the World Wide Web . Contrary to some common usage, the Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks , linked by copper wires, fiber-optic cables, wireless connections etc.; the Web is a collection of interconnected documents , linked by hyperlinks and URLs , and is accessible using the Internet. The Internet also provides many other services including e-mail , file sharing
