the story of the internet

the story of the internet

A single person did not create the Internet that we know and use today. Below is a listing of different people who have helped contribute to and develop the Internet.

The idea

The initial idea of the Internet is credited to Leonard Kleinrock after he published his first paper entitled "Information Flow in Large Communication Nets" on May 31, 1961.
In 1962, J.C.R. Licklider became the first Director of IPTO and gave his vision of a galactic network. Also, with ideas from Licklider and Kleinrock, Robert Taylor helped create the idea of the network that later became ARPANET.

Initial creation

The Internet as we know it today first started being developed in the late 1960's in California in the United States.
In the summer of 1968, the Network Working Group (NWG) held its first meeting, chaired by Elmer Shapiro, at the Stanford Research Institute (SRI). Other attendees included Steve CarrSteve CrockerJeff 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 created the Interface Message Processor (IMP) specifications. Bolt Beranek and Newman, Inc. (BBN) was later awarded the contract to design and build the IMP subnetwork.

General public learns about Internet

The UCLA (University of California, Los Angeles) put out a press release introducing the public to the Internet on July 3, 1969.

First network equipment

On September 2, 1969, the first data moves from the UCLA host to the switch. The picture to the right is Leonard Kleinrock next to the IMP.

The first 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. The connection not only enabled the first transmission to be made, but is also considered 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.
The Internet in 1969

E-mail is developed

Ray Tomlinson sends the first network e-mail in 1971. It's the first messaging system to send messages across a network to other users.

TCP is developed

Vint CerfVinton Cerf and Robert Kahn design TCP during 1973 and later publish it with the help of Yogen Dalal and Carl Sunshinein December of 1974 in RFC 675. Most people consider these two people the inventors of the Internet.

First commercial network

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

Ethernet is conceived

Bob Metcalfe develops the idea of Ethernet in 1973.

The Modem is introduced

Dennis Hayes and Dale Heatherington released the 80-103A Modem in 1977. TheModem and their subsequent modems become a popular choice for home users to connect to the Internet and get online.

TCP/IP is created

In 1978, TCP splits into TCP/IP, driven by Danny CohenDavid Reed, and John Shochto support real-time traffic. The creation of TCP/IP help create UDP and is later standardized into ARPANET on January 1, 1983. Today TCP/IP is still the primary protocolused on the Internet.

DNS is introduced

Paul Mockapetris and Jon Postel introduce DNS in 1984, which also introduces the domain name system. The first Internet domain name, symbolics.com, is registered on March 15, 1985 by Symbolics, a Massachusetts computer company.

First commercial dial-up ISP

The first commercial Internet Service Provider (ISP) in the US, known as "The World", is introduced in 1989. The World was the first ISP to be used on what we now consider to be the Internet.

HTML

Tim Berners-LeeIn 1990, Tim Berners-Lee develops HTML, which made a huge contribution to how we navigate and view the Internet today.

WWW

Tim Berners-Lee introduces WWW to the public on August 6,1991. The World Wide Web (WWW) is what most people today consider the "Internet" or a series of sites and pages that are connected with links. The Internet had hundreds of people who helped develop the standards and technologies used today, but without the WWW, the Internet would not be as popular as it is today.

First graphical Internet browser

NCSA Mosaic 1.0Mosaic is the first widely used graphical World Wide Web browser developed and first released on April 22, 1993 by the NCSA with the help of Marc Andreessen and Eric Bina. A big competitor to Mosaic was Netscape, which was released a year later. Today, most of the Internet browsers we use today, e.g. Internet Explorer, Chrome, Firefox, etc., got their inspiration from the Mosaic browser.

Java and JavaScript

Originally known as oakJava is a programming language developed by James Gosling and others at Sun Microsystems. It was first introduced to the public in 1995 and today is widely used to create Internet applications and other software programs.
JavaScript was developed by Brendan Eich in 1995 and originally known as LiveScript. It was first introduced to the public with Netscape Navigator 2.0 and was renamed to JavaScript with the release of Netscape Navigator 2.0B3. JavaScript is aninterpreted client-side scripting language that allows a web designer the ability to insert code into their web page.

Related Questions

That is a great overview, but who are the key inventors of the Internet?
If you had to isolate the key inventors of the Internet, it would have to be two people:Vinton Cerf and Robert Kahn. The WWW, which is different from the Internet, but what most people think of as the "Internet", was invented later by Tim Berners-Lee.

Facebook and Netflix reset passwords after data breaches




With vast swathes of data being sold on the dark web in recent weeks following high-profile 
breaches, many sites are encouraging users to change their passwords, even if they weren't directly affected.


Facebook and Netflix appear to be taking this a step further with reports a number of users are being forced to update their credentials.

According to security researcher Graham Cruelly, Facebook users are being shown a warning message that reads: "Recently, there was a security incident on another website unrelated to Facebook. Facebook was not directly affected by the incident but your Facebook account is at risk because you were using the same password in both places."

It then goes on to say that to secure their account, the user will need to answer security questions and change their password. It also adds: "For your protection, no one can see you on Facebook until you finish."

By comparison, Netflix is emailing members claiming: "We believe that your Netflix account credentials may have been included in a recent release of email addresses and passwords from an older breach at another company. Just to be safe, we’ve reset your password as a precautionary measure."


Neither Facebook, nor Netflix, are saying they have been hacked or suffered data breaches and the other website referred to is likely to be LinkedIn.

In 2012, a rumoured 167 million account details were stolen from LinkedIn. Initially the data was being sold on the dark web for five bitcoin, this amounts to around $2,200 (£1,500). It has since dropped in price and is at around half of this value.


Facebook and Netflix are being cautious because many people - including Facebook's own Mark Zuckerberg it transpired earlier this week - use the same passwords on multiple accounts.

Security blogger Brian Krebs was sent one of the Netflix emails, and he said he believes more sites may follow suit in the coming weeks.

Experts are advising people change their passwords on their accounts, or make each password unique, to protect themselves. They should also enable two-factor authentication where available.

What is the deep web

Deep web hidden web
"Deep web" is distinct from "dark web".(invisible web or hidden web) The "dark web" is the encrypted network that exists between Tor servers and their clients, whereas the "deep web" is simply the content of databases and other web services that for one reason or another cannot be indexed by conventional search engines.
The deep web includes many very common uses such as web mail, online banking but also paid for services with a paywall such as video on demand, and many more.
Computer scientist Mike Bergman is credited with coining the term deep web in 2000 as a search indexing term
The first conflation of the terms "deep web" and "dark web" came about in 2009 when the deep web search terminology was discussed alongside illegal activities taking place on the Freenet darknet.
Since then, the use in the Silk Road's media reporting, many people and media outlets, have taken to using Deep Web synonymously with the dark web or darknet, a comparison Bright Planet rejects as inaccurate and consequently is an ongoing source of confusion. Wired reporters Kim Zetter and Andy Greenberg recommend the terms be used in distinct fashions.

size
It is impossible to measure, and harsh to put estimates on, the size of the deep web because the majority of the information is hidden or locked inside databases. Early estimates suggested that the deep web is 400 to 550 times larger than the surface web. However, since more information and sites are always being added, it can be assumed that the deep web is growing exponentially at a rate that cannot be quantified.
Estimates based on extrapolations from a study done at University of California, Berkeley in 2001 speculate that the deep web consists of about 7.5 petabytes. More accurate estimates are available for the number of resources in the deep web: research of He et al. detected around 300,000 deep web sites in the entire web in 2004,  and, according to Shestakov, around 14,000 deep web sites existed in the Russian part of the Web in 2006. 
Content types 
  1. Contextual Web: pages with content varying for different access contexts (e.g., ranges of client IP addresses or previous navigation sequence).
  2. Dynamic content: dynamic pages which are returned in response to a submitted query or accessed only through a form, especially if open-domain input elements (such as text fields) are used; such fields are hard to navigate without domain knowledge.
  3. Limited access content: sites that limit access to their pages in a technical way (e.g., using the Robots Exclusion Standard or CAPTCHAs, or no-store directive which prohibit search engines from browsing them and creating cached copies)
  4. Non-HTML/text content: textual content encoded in multimedia (image or video) files or specific file formats not handled by search engines.
  5. Private Web: sites that require registration and login (password-protected resources).
  6. Scripted content: pages that are only accessible through links produced by JavaScript as well as content dynamically downloaded from Web servers via Flash or Ajaxsolutions.
  7. Software: certain content is intentionally hidden from the regular Internet, accessible only with special software, such as Tor, I2P, or other darknet software. For example, Tor allows users to access websites using the .onion host suffix anonymously, hiding their IP address.
  8. Unlinked content: pages which are not linked to by other pages, which may prevent web crawling programs from accessing the content. This content is referred to as pages without backlinks (also known as inlinks). Also, search engines do not always detect all backlinks from searched web pages.
  9. Web archives: Web archival services such as the Wayback Machine enable users to see archived versions of web pages across time, including websites which have become inaccessible, and are not indexed by search engines such as Google
