INTERNET the word everyone is familiar about the internet was not always the same as we see it today. In Earlier days an individual presented a thought of data that transfer in large amount through any medium that person was “Mr. Leonard Kleinrock” and the paper he wrote was titled as “Information Flows in Large Communication Nets” this Paper was published on May 31 1961.

If you are thinking that there is only one person behind the idea or creation of internet than I must have to tell you that my friend you are wrong because there is a chain of person and contribution of each individual to some extend due to which we are seeing the internet as it is today.

Let have a look on the series of invention and processes that completed to make the structure of internet as we see it today.

Initial Thoughts:

As I have already mentioned above that Mr. Leonard Kleinrock wrote a paper and shared his thoughts on “Information Flow in Large Communication Nets”. This paper was published for public on 31 May, 1961. In 1962, Mr. J.C.R. Licklider became the first director of IPTO (Information Processing Technology Office). As a quick intro of IPTO is that it is an agency that work under DARPA (Defense Advance Research Project Agency) the IPTO was responsible for heading its effort and helped invest in technologies and research.

So Mr. Licklider supported the idea of Mr. Kleinrock and gave his thoughts a great vision and as a effect of which ARPANET came into existence.


Internet which we use today was initially developed in the 1960’s in California United States.

A company called NWG (Network Working Group) organized a meeting at SRI (Stanford Research Institute) chaired by Elmer Shapiro and attended by Steve Carr, Steve Crocker, Jeff Rulifson and Ron Stoughton. This group discussed regarding issues and solutions for getting hosts to communicate with each other in the meeting.

In December 1968 a Research Paper was published by Mr. Elmer Shapiro “A Study of Computer Network Design Parameters”. Based on this Research Paper and all the earlier work done by Thomas Marill and Paul Baran. Barry Wessler and Lawrence Roberts invented the idea of IMP (Interface Message Processor) later than BBN (Bolt Beranek and Newman, Inc.) was awarded the contract to design and establish the IMP subnet work.

First Part of the Internet:

August 29, 1969 a memorable day in the history of internet was because after all the theories the first practical equipment a switch and the first piece network called IMP was made and send to UCLA (University of California, Los Angeles).

2 September 1969 a remarkable day because world’s first data movement was recorded from the UCLA host.

First Ever Message Send Through IMP:

At 10:30 pm on 29 October 1969 world’s first internet message was sent from Professor Leonard Kleinrock’s laboratory at UCLA to a computer that was setup at SRI and that connection between the two computers proves to be the backbone of first internet.

The first distributed message between these two computers was an attempt by Charley S. Kline to log in in to the computer placed at the other hand in SRI. However the first attempt to login was unsuccessful because the computer that was placed at SRI crashed but shortly after the crash the hurdle was solved and the second attempt was made successful.

Electronic Mail and Transmission Control Protocol:

After the success of IMP in 1969 Ray Tomlison in 1971 successfully sends the first network E-mail and shortly after this in 1973 Vinton Cerf and Robert Kahn designed TCP (Transmission control protocol) and most people todays thinks them as the inventor of Internet. Coming back to the topic lets have a quick intro of what TCP is and what it does. Basically, TCP is a set of rules which is called protocols in computer science terminology the TCP decides how the information which is been sent from one computer to another should be packed in packages and as well as how to make it reach to its destination.

Arpanet and Ethernet:

Now coming into 1970’s two main events took place which were:

  1. In 1974 the first ever commercial version of Arpanet also known as Telenet is introduced and it is considered as the first ISP (Internet Service Provider).

2. In 1973 Bob Metcalf develops the idea of Ethernet.

Introduction to Modems:

As the topic clearly states let guide you to the intro of what this part does. Since Modem is a huge topic to cover so let make it short and to understand about modem all you need to know is Modems are basically a hardware device or equipment that works to connect your computers, laptops or routers to a broadband network so that you can surf anything you want on internet. So in 1977 Mr. Dennis Hayes introduced and released the 80-103A Modem and that where the concept of modem comes from.

Splits of TCP into TCP/IP and UDP:

As I have told you earlier before what is TCP now in 1978 some individuals proposed the idea to split TCP into TCP/IP in which just some minor rules / protocols were changed and an alternative of TCP also came into existences known as UDP (User Datagram Protocol) now what is alternative does ?

This alternative UDP works more faster than TCP/IP because UDP does not convert every transmission into packets which allows the data to move faster than TCP/IP and in 1983 it was standardized to ARPANET but TCP/IP is still used as the primary protocol on internet today.

Introduction to DNS:

Domain Name System (DNS) is basically a service in which companies or individual register there domain on the internet so that people can surf through their websites. The idea of DNS was proposed and designed by Paul Mockapetris and Jon Postel in 1984 and the first domain name was officially registered on March 15 1985 by a Massachusetts Computer company.

Commercial Dial-ups:

The World was introduced as the first commercial ISP (Internet Service Provider) in US in 1989 which we consider as internet today.

Hypertext Markup Language:

Html (Hypertext Markup Language) is a coding language that was introduced by Mr. Tim-Berners in 1990 which provide to be a huge contribution to the internet so far the html works for how we navigate and see the internet today.

The first-ever website created on the internet was “” and it was also developed by Tim-Berners at CERN and it was available for people on August 6, 1991.

World-Wide Web:

Then later on in 1991 Tim-Berners introduce the world with www (World-Wide Web) and this www is what people think is “Internet” but there are hundreds of people who sets the standards and technologies of internet that we use today but if www was not invented than I doubt the internet wouldn’t be that popular that it is today.

Graphical Internet Browser:

The world’s first graphical user interface was created in 1933 by NCSA and was named as “Mosaic”. After Mosaic the big competitor for NCSA was Netscape which was released just a year after Mosaic released. The internet browsers that we use today (internet explorer, goggle chrome, Firefox and Safari) got their inspiration from Mosaic and Netscape.


Java Script previously known as Live Script was originally known as oak. Java is a programming language that was developed by James Gosling and employees of SUN Microsystems in lately 1995. Java is the programming language that is still widely used to create internet applications and other software’s.

This Programming language Java was created in 1995 by Mr. Brendan Eich and was first released with Netscape 2.0. Basically Javascript is the programming language that allows the designer to insert code on their web pages.

Now as you have already read the complete history of internet you can know that efforts of how many individual their researches, proposal, invention and published paper make the internet that we see and use today. But the efforts are not stopped it’s still continuing and there is lot and lot more to come in the coming days.
