The History of the
Internet
1962
Paul Baran, of the RAND Corporation (a
government agency), was commissioned by
the U.S. Air Force to do a study on how it
could maintain its command and control
over its missiles and bombers, after a
nuclear attack.
1968
The physical network was constructed in
1969, linking the University of California at
Los Angeles, SRI (in Stanford), University of
California at Santa Barbara, and University
of Utah.
1972


The first e-mail program was created by
Ray Tomlinson of BBN allowing
communications between hosts running on
the same network.
1973
Development began on the protocol later
to be called TCP/IP, which allowed
different computer networks to
interconnect and communicate with each
other.
1974
First Use of term Internet by Vint
Cerf and Bob Kahn in paper on
Transmission Control Protocol.
1976
Dr. Robert M. Metcalfe develops
Ethernet, which allowed coaxial cable
to move data extremely fast. This
network linked the United States with
Europe.
1979
USENET (the decentralized news group
network) was created by Steve Bellovin, a
graduate student at University of North
Carolina, and programmers Tom Truscott
and Jim Ellis.
1983
On January 1st, every machine connected to
ARPANET had to use TCP/IP. TCP/IP
became the core Internet protocol and
replaced NCP entirely. This made it much
easier for people to access other servers,
because they no longer had to remember
numbers.
1984
Upgrade to CSNET was
contracted to MCI. New circuits
would be T1 lines,1.5 Mbps
which is twenty-five times faster
than the old 56 Kbps lines.
1985
The National Science Foundation
began deploying its new T1 lines,
which would be finished by 1988.
1988
Soon after the completion of the T1
NSFNET backbone, traffic increased so
quickly that plans immediately began
on upgrading the network again.
1991
CSNET (which consisted of 56Kbps
lines) was discontinued having fulfilled
its important early role in the provision
of academic networking service.
1992
Internet Society is chartered. World-Wide Web
released by CERN. NSFNET backbone
upgraded to T3 (44.736Mbps)
1993
InterNIC created by NSF to provide specific
Internet services: directory and database
services (by AT&T), registration services
(by Network Solutions Inc.), and
information services (by General
Atomics/CERFnet).
1994
No major changes were made to the physical
network. Hundreds of thousands of new hosts were
added to the INTERNET during this time period.
Pizza Hut offers pizza ordering on its Web page.
First Virtual, the first cyberbank, opens.
1996
Currently the Internet Society, is trying to figure out
new TCP/IP to be able to have billions of addresses,
rather than the limited system of today. The
problem that has arisen is that it is not known how
both the old and the new addressing systems will
be able to work at the same time during a
transition period.
2004
Internet speed record broken. Researchers
successfully sent data using a 10Gigabit
Ethernet link between the University of
Tokyo and the CERN research center in
Geneva, Switzerland. The T110 delivered
sustained 7.57… that's enough speed to
transfer a full-length DVD anywhere in the
world in less than five seconds.
2005
During 2005 it's estimated that the onebillionth user went online. Netcraft survey
reports there are more than 74 million web
sites online, while in 1993 only 130 web
sites existed online.
2006
German and Japanese scientists
collaborated to shatter the world record
for data transmission speed. By
transmitting a data signal at 2.56
terabits per second over a 160-kilometer
link (equivalent to 2,560,000,000,000
bits per second or the contents of 60
DVDs) the researchers bettered the old
record of 1.28 terabits per second held
by a Japanese group. By comparison,
the fastest high-speed links currently
carry data at a maximum 40 Gbit/s, or
around 50 times slower.

Listserves…
The listserv I chose is the
chatboard on Teachers.net.
The list serve also offers,
classifieds, lessons, jobs,
mailrings, projects, live
chats and advertising, all
directed towards teachers.
The forums have a
wide variety of topics
dealing with
language, subject
area, grade levels,
etc.
How I will use this Listserv…
1.

4.
To get ideas for lesson planning
To contact other special ed. teachers
regarding goal writing
To seek the advice of more experienced
“mentor” teachers
Simply to have another perspective on
teaching!
Blogs…
The blog I choose is The
Endless Faculty Room.
This blog offers, “A
place for educators to
discuss issues, offer
ideas, thoughts, and
opinions; share
resources, lesson
plans, best practices,
and occasionally let
off steam.” It also
encourages a good
time and constructive
comments and
suggestions.
How I will use this Blog…

Reduce stress by venting a little
steam
Listen to other educators that are
having some of the same problems
as me
Realize that the same problems are
shared by others
Personal enjoyment!
POWER Library…


The POWER Library is
offered as a service of
Pennsylvania's public
libraries, school libraries
and the State Library.
The POWER library allows
you to access thousands of
full text periodical articles,
newspapers, a major
encyclopedia, plus
photographs, pictures,
charts, maps, reference
materials for young people
and more. You will find
materials of interest in
most subject areas for all
age groups from young
children to adults.
How I will use POWER Library…
I will use the POWER Library
to assist students in locating
materials for their Junior and
Senior Projects. The site
offers online reference
materials that can be
accessed online. Also,
students can have access to
books and other reference
materials from schools and
libraries across Pennsylvania.
The online encyclopedias
are particularly nice to
have access to right in
the classroom!
Newsgroups…
The newsgroup that I chose to
use is The Math Forum at Drexel.
This newsgroup is composed of
teachers, mathematicians,
researchers, students, and
parents using the power of the
Web to learn math and improve
math education.
They offer offer a wealth of
problems and puzzles; online
mentoring; research; team
problem solving; collaborations;
and professional development.
Students have fun and learn a
lot. Educators share ideas and
acquire new skills.
