This is How The Internet Was Invented (Animated Video)

How The Internet Was Invented The Internet has proved to be one of the most
useful technologies invented in the present day. It is a vast carrier of a wide range of information,
resources and services like multimedia data, emails, file transfer and sharing, e-commerce,
online chat, gaming and so on. The Internet has made life so easy and comfortable
that no one needs to travel miles just to get needed information as was done in the
olden days. Relevant information, products or services
can now be gotten through the Internet at a reliable and faster rate. HOW IT CAME TO BE
The term Internet was first adopted in the first letter published on Transmission Control
Protocol (TCP) in December 1974. The term Internet is an abbreviation for Internetworking. inter meaning “between”, and “net”
was short for “network”. An Internet is any network using TCP/IP. The invention of the Internet was a project
carried out by different pioneering scientists, programmers and engineers, therefore, its
invention cannot be attributed only to one person because each of these people developed
features and ideas and they merged these ideas together to create what the Internet is today. The Internet passed through various stages
of development before it became what it is today. Many scientists had already anticipated the
existence of worldwide networks of information. To start with, Nikolai Tesla toyed with the
idea of a world wireless system in the early 1900s. The first practical semantic for the Internet
did not arrive until the early 1960s when MIT’s JCR, Licklider popularized the idea
of the InterGalactic network of computers in August 1962. Discussing his “Inter Galactic Network”
concept, Licklider envisioned a globally interconnected set of computers through which everyone could
quickly access data and programs from any site. This concept was very much like the Internet
of today. Licklider became the first head of the computer
research program at DARPA (The Defense Advanced Research Projects Agency) in October 1962. While at DARPA he convinced his successors,
Ivan Sutherland, Bob Taylor, and MIT researcher Lawrence G. Roberts, of the importance of
this networking concept. Leonard Kleinrock at MIT published the first
paper on packet switching theory in July 1961 and the first book on the subject in 1964. Kleinrock convinced Roberts of the theoretical
feasibility of communications using packets rather than circuits, which was a major step
along the path towards computer networking. Another key step was to make the computers
“talk” together. To explore this, in 1965 while working with
Thomas Merrill, Roberts connected the TX-2 computer to the Q-32 in California with a
low-speed dial-up telephone line creating the first (however small) wide-area computer
network ever built. The result of this experiment was the realization
that the time-shared computers could work well together, running programs and retrieving
data as necessary on the remote machine, but that the circuit switched telephone system
was totally inadequate for the job. Kleinrock’s conviction of the need for packet
switching was confirmed. The ARPANET (Advanced Research Projects Agency
Network) was funded by the U.S Department of defense. It was a contract awarded by the US Department
of Defense directed by Robert Taylor and managed by Lawrence Roberts in 1960. One of the features of ARPANET was that it
used Packet Switching to allow multiple computers to communicate on a single network. Another major evolution was the development
of the packet switching but before it was introduced, there was an issue of connecting
separate physical networks to one logical network. The early network used message switch systems. It required a rigid routing structure prone
to a single point of failure. In the 1960s, the Research and Development
Corporation (RAND) produced a study of a survivable network for the U.S military in the event
of nuclear war, information that needed to be transmitted across Baran network would
be divided into what he called the message blocks. Donald Davies volunteered to help in this
and he was the first to put into practice a Local Area Network based on the packet switching. The idea and concept of Wide Area Network
originated in a computer laboratory in the UK. The packet switching network was a rapid network
design that divided messages into arbitrary packets. Following the design of the Packet Switch,
Donald Davies became interested in data communication for computer networks. The Packet Switching network was first demonstrated
by Donald Davies at the National Physics Laboratory in the UK. The laboratory later became a test bed for
other UK researchers for almost two decades. Davies’ concept of packet switch would later
be adopted and applied for the Wide Area Network by Larry Roberts. In 1965, Davies designed and proposed a national
data network based on Packet Switching. He made a proposal the following year that
would make him use an interface computer to act as a router. It was not taken up nationally until 1967
when the pilot experiment brought in the feasibility to Packet Switched network and by 1969, he
built the mask switched network to meet the needs of the multidisciplinary laboratory. In late 1966 Roberts went to DARPA to develop
the computer network concept and quickly put together his plan for the ARPANET based on
the packet network. In 1969, the first message was sent over the
ARPANET from Leonard Kleinrock’s laboratory at the University of California, Los Angeles
to the second network node at the Stanford research institute. ARPANET, as it was known, was soon combined
with technology like email. The email was developed in 1971 by Ray Tomlinson
and was so useful that by 1973 it made up three-quarters of the traffic on the network. By this time, there were 40 individual networks
connected to ARPANET. The first connection across the Atlantic Ocean
also happened in 1973, when University College London was connected. Around this time, other networks similar to
ARPANET were being created in other countries. A system was developed to connect these networks
together: The technology to develop a better Internet
continued to grow in the 1970s after Robert Taylor, a scientist developed the TCP and
IP (Internet Protocol). The TCP and IP set standards for how data
could be transmitted between multiple networks. By 1976, 12 computers and 75 terminal devices
were attached to the Packet Switch network. The network was replaced by ARPANET. The ARPANET later adopted the TCP and IP on
January 1, 1983. After this, researchers began to assemble
the “network of networks” that would become the modern Internet today. A portion of ARPANET was broken off as a separate
network in 1984 by the US military. They called it the MILNET that is the Military
Network. The MILNET became an unclassified network
as it was for the military only In the same period the NIPRNET (Non-classified
Internet Protocol), a private network used to exchange non-classified data that needed
strict control over its dissemination was government owned and restricted to non-commercial
use. The Internet began to take shape gradually
as it became recognizable in 1990. In 1990 the first publicly available ISP (Internet
service provider) started and Internet access became a possibility to the general public. The Web which was invented by Tim Berners-Lee
helped to popularize the Internet among the public by linking hypertext document into
an information system accessible from any node on the network. This step served as a crucial one in developing
the vast trove of information that most of us today can access on a daily basis. In 1993, the Web browsers came into play such
as the Mosaic and the website for the government of the United States. The Hotmail was launched as the first Web-based
email service. The Internet today has a revolutionary impact
on culture, commerce, and technology. The Internet represents one of the most successful
examples of the benefits of sustained investment and commitment to the development of information
and infrastructure. Thank God for the Internet, you wouldn’t
