The publicly accessible worldwide system of interconnected computer networks.
Data is transmitted by packet switching using a standardised Internet Protocol (IP). The internet is made up of thousands of smaller commercial, academic, domestic, and government networks. It carries various types of 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, fibre-optic cables, etc.; the Web is a collection of interconnected documents, linked by hyperlinks and URLs, and is accessible using the Internet.
