The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, 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 inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network called the ARPANET started working in 1969.
The concept was expanded in 1982 by Vint Cerf and Bob Kahn with their paper "A Protocol for Packet Network Intercommunication". It was designed as an experimental military project under the auspices of DARPA (Defense Advanced Research Projects Agency) with Barbara Liskov as one its early developers.
The advanced research projects agency first connected four major computers at universities in southern California–UCLA, Stanford Research Institute (now SRI International), UCSB, and the University of Utah–in September 1969.
