How The Internet was Created

Did you ever have one of those burning questions to ask that just pops into head. I’m sure one of those questions was who invented the internet? well … a single person did not create the Internet that we know and use today. Below is a listing of several different people who’ve helped contribute and develop the Internet.

1961-The idea!

The initial idea is credited as being Leonard Kleinrock’s (pictured right)Kleinrock Grayscale after he published his first paper entitled “Information Flow in Large Communication Nets” on May 31, 1961.

In 1962 J.C.R. Licklider becomes the first Director of IPTO and gave his vision of a galactic network. In addition to the ideas from Licklider and Kleinrock, Robert Taylor helped create the idea of the network, which later became ARPANET.

1968-Initial creation

The Internet as we know it today first started being developed in the late 1960’s.

In the summer of 1968, the Network Working Group (NWG) held its first meeting chaired by Elmer Shapiro with the Stanford Research Institute (SRI) with attendees: Steve Carr, Steve Crocker, Jeff Rulifson, and Ron Stoughton. In the meeting the group discussed solving issues related to getting hosts to communicate with each other.

In December 1968, Elmer Shapiro with SRI released a report “A Study of Computer Network Design Parameters.” Based on this work and earlier work done by Paul Baran, Thomas Marill and others; Lawrence Roberts and Barry Wessler helped to create the final version of the Interface Message Processor (IMP) specifications. Bolt Beranek and Newman, Inc. (BBN) was later awarded the contract to design and build the IMP sub network.

Introduction of the Internet to the general public

UCLA puts out a press release introducing the public to the Internet on July 3, 1969.

1969-First network equipment

In the picture to the right, is a picture of Leonard Kleinrock next to the IMP.

The first distributed message and network crash

On Friday October 29, 1969 at 10:30 p.m., the first Internet message was sent from computer science Professor Leonard KleinRock’s laboratory at UCLA, after the second piece of network equipment was installed at SRI. This connection not only enabled the first transmission to be made, but is also considered to be the first Internet backbone.

The first message to be distributed was “LO”, which was an attempt at “LOGIN” by Charley S. Kline to log into the SRI computer from UCLA. However, the message was unable to be completed because the SRI system crashed. Shortly after the crash, the issue was resolved and he was able to log into the computer.

1972-E-mail is developed

Ray TomlinsonRay Tomlinson (pictured right) introduces network e-mail in 1972.  The first messaging system to send messages across a network to other users. The first email Ray Tomlinson sent was a test e-mail. It was not preserved and Tomlinson describes it as insignificant, something like “QWERTYUIOP”. This is commonly misquoted as “The first e-mail was QWERTYUIOP”. Tomlinson later commented that these “test messages were entirely forgettable and I have, therefore, forgotten them.

At first, his email messaging system wasn’t thought to be a big deal. When Tomlinson showed it to his colleague Jerry Burchfiel, he said “Don’t tell anyone! This isn’t what we’re supposed to be working on.

1973-TCP is developed

Vinton Cerf and Robert Kahn (pictured left) design TCP during 1973 and later publish it with the help of Yogen Dalal and Carl Sunshine in December of 1974 in RFC 675.  TCP/IP provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. It has four abstraction layers which are used to sort all Internet protocols according to the scope of networking involved. From lowest to highest.

1974-First commercial network

A commercial version of ARPANET known as Telenet is introduced in 1974 and considered by many to be the first Internet Service Provider (ISP).

1973-Ethernet is conceivedBob Metcalfe

1978-TCP/IP is created

In 1978 TCP splits into TCP/IP driven by Danny Cohen, David Reed, and John Shoch to support real-time traffic. This allows the creation of UDP. TCP/IP is later standardized into ARPANET in 1983 and is still the primary protocol used for the Internet.

1984-DNS is introduced

Paul Mockapetris and Jon Postel introduce DNS in 1984.

1990-HTML

1991-WWW
