The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to communicate with each other. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the web pages that make up the World Wide Web (WWW) and the infrastructure to support email and streaming services.
