The Internet began in 1957 with the creation of ARPANET by the U.S. Department of Defense to compete against the USSR in technology development. In 1969, the first connection was made between computers at UCLA and SRI, marking the beginning of ARPANET which became the first operational packet switching network and the core of what would become the global Internet. Major developments included the introduction of TCP/IP in 1977 allowing for seamless transmission, the creation of the World Wide Web in 1990 at CERN, and the launch of popular websites and apps in the 1990s-2000s which drove widespread commercial and public use of the Internet.

1. INTERNET AND ITS HISTORY
BY- PANKAJ SINGH CHANDEL

2. DEFINATION:-
 Internet is the global system of interconnected computer networks
that use the standard Internet protocol suite(often called TCP/IP)
 Internet is a network of networks that consists of millions of private,
public, academics, business, and government networks that are
linked by a broad array of electronics, wireless and optical
networking technologies.

3. DIFFERENT ERA OF INTERNET
 1957:-
• The USSR launches the first satellite, SPUTNIK. To compete against the
USSR's success at launching the first satellite, the United States Department of
Defense creates the Advanced Research Projects Agency (ARPA). ARPA is responsible
for the development of new technology for use by the military.
