The document provides a history of the internet, beginning with its origins in the 1950s with the development of computers. It describes how the US Department of Defense funded research in the 1960s to create a network (ARPANET) that would continue functioning even if parts were damaged, laying the foundation for today's internet. Key developments include the creation of TCP/IP in the 1970s and 1980s to standardize network communication and the introduction of the World Wide Web in the 1990s, which led internet usage to grow tremendously, reaching over 3 billion users globally by 2014.

OF
INTERNET

2. Definition of Internet
 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.

3. History of internet
 It all begins with development of computer in 1950’s.
 The internet grew out of an experiment in 1960’s by the U.S. Department Of
Defense. The DoD wanted to create a computer network that would
continue to function in the event of disaster, such as nuclear war.If part of the
network was damage or destroyed, the rest of the system still had to work.
That network was APANET(advanced research project agency) which linked
U.S. scientific & academic researchers. It was the forerunner of today’s
internet.

4.  1968-DARPA(Defance Advanced Research Projects Agency) contracts with
BBN(Bolt, Beranek & Newman) to create ARPANET.
 1974-TCP specification by Vint Cerf
 1984-on jannuary1, the internet with its 1000 hosted convert en masse to using
TCP/IP for its messaging.
 1984-Domain Name Server (DNS) introduce.
 1986-NSFNET created a high speed backbone(56Kbps) to interconnect
supercomputer centers.
 1992- WWW released by CERN(a physics research institute in Switzerland) no.
of hosts breaks 1,000,000.
 1995- .com sites exceed

5. Robert Kahn is an
American Internet
pioneer, engineer &
computer scientist , who
along with Vinton Cerf
invented
TCP(Transmission
Control Protocol ) &
Internet Protocol which
are heart of internet

6. Growth of Internet
 Internet usage has seen tremendous growth. From 2000 to
2009, the number of Internet users globally rose from 394
million to 1.858 billion. By 2010, 22 percent of the world's
population had access to computers with 1
billion Google searches every day, 300 million Internet users
reading blogs, and 2 billion videos viewed daily
on YouTube. In 2014 the world's Internet users surpassed 3
billion or 43.6 percent of world population, but two-thirds of
the users came from richest countries, with 78.0 percent of
Europe countries population using the Internet, followed by
57.4 percent of the Americas.

8. The uses of the Internet
 Send (upload) or receive (down load) files between computers.
 Participate in discussion groups, such as mailing lists and
newsgroups.
 Surfing the web.
