    The 
Internet is the global system of interconnected 
computer networks that use the 
Internet protocol suite (TCP/IP) to link billions of devices 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, 
newsgroups, 
voice over IP telephony, and 
peer-to-peer networks for 
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 via computer networks.
[1] The primary precursor network, the 
ARPANET,  initially served as a backbone for interconnection of regional academic  and military networks in the 1980s. The funding of the 
National Science Foundation Network  as a new backbone in the 1980s, as well as private funding for other  commercial extensions, led to worldwide participation in the development  of new networking technologies, and the merger of many networks.
