HISTORY OF THE INTERNET
In 1962, J.C.R. Licklider of Massachusetts Institute of Technology (MIT) proposed
a global network of computers for research and
development in scientific and military fields.

HISTORY OF THE INTERNET
Licklider moved to Defense Advanced Research Project
Agency (DARPA) in late 1962 to head the work to
develop the global network of computers.

HISTORY OF THE INTERNET
Leonard Kleinrock of MIT developed the theory of packet switching, which
was the basis for Internet connections.

HISTORY OF THE INTERNET
Lawrence Roberts of MIT connected a Massachusetts computer with a California
computer in1965 over a dial-up telephone lines,
which showed the feasibility of WAN.

HISTORY OF THE INTERNET
Kleinrock’s packet switching theory was confirmed.
Roberts moved over DARPA in 1966 and developed
ARPANET.

Charley Kline at UCLA sent the first packets on
ARPANET as he tried to connect to Stanford
Research Institute on 29 October 1969.

Email was adapted for ARPANET by Ray Tomlinson in 1972. He picked the @ symbol to link username
and address.

HISTORY OF THE INTERNET
The telnet protocol was published as a Request for Comments (RFC) in 1972 to share developmental work
throughout community.

Student Bob Metcalfe’s dissertation on Packet
Networks.

HISTORY OF THE INTERNET
The Internet matured in the 70s as a result of the TCP/IP Architecture proposed and developed by Bob Kahn and
Vint Cerf at Stanford Research Institute.

HISTORY OF THE INTERNET
The TCP/IP was adopted by Defense Department in
1980 to replace the Network Control Protocol
(NCP) and universally adopted by 1983.

In 1986, the National Science Foundation
funded NSFNet as a cross country 56 Kbps backbone
for the Internet.

its non-commercial government and research
uses.

In 1989, Tim Berners-Lee proposed a new protocol
for information distribution at the Center for European Nuclear Research (CERN) in
Switzerland.

HISTORY OF THE INTERNET
This protocol, which was based on hypertext (a
system embedding links in text to link to other text) became the World Wide
Web in 1991.

Internet was developed at the University of
Minnesota.

HISTORY OF THE INTERNET
The development in 1993 of the graphical browser Mosaic
by Marc Andreessen at the National Center for
Supercomputing Applications (NCSA) gave the protocol its
big boost.

THE INTERNET VS. THE WEB
The Internet is the actual network.
It is made up of wires, cables, satellites, and rules for exchanging information.
![Page 31: COMPED9 Module 2 The Internet and the Web](https://reader030.fdocuments.us/reader030/viewer/2022032514/55d38557bb61eb443f8b46b1/html5/thumbnails/31.jpg)
THE INTERNET VS. THE WEB
Being connected to this network is often described
as being ONLINE.
