Our criteria By what criteria would we determine what was a primitive Internet? We will examine the various verifiable events according to the following criteria Was it a connection between networks? Did it involve computers? Did it involve humans communicating with each other?
The Victorian Internet The concept of data communication — transmitting data between two different places through an electromagnetic medium such as radio or an electric wire — pre-dates the introduction of the first computers.
Such communication systems were typically limited to point to point communication between two end devices. Telegraph systems and telex machines can be considered early precursors of this kind of communication.
The Telegraph in the late 19th century was the first fully digital communication system. Fundamental theoretical work in data transmission and information theory was developed by Claude ShannonHarry Nyquistand Ralph Hartley in the early 20th century.
Early computers had a central processing unit and remote terminals.
As the technology evolved, new systems were devised to allow communication over longer distances for terminals or with higher speed for interconnection of local devices that were necessary for the mainframe computer model. These technologies made it possible to exchange data such as files between remote computers.
However, the point-to-point communication model was limited, as it did not allow for direct communication between any two arbitrary systems; a physical link was necessary.
The technology was also considered unsafe for strategic and military use because there were no alternative paths for the communication in case of an enemy attack.
Development of wide area networking With limited exceptions, the earliest computers were connected directly to terminals used by individual users, typically in the same building or site. Such networks became known as local area networks LANs.
Networking beyond this scope, known as wide area networks WANsemerged during the s and became established during the s. For each of these three terminals, I had three different sets of user commands. So if I was talking online with someone at S. If you have these three terminals, there ought to be one terminal that goes anywhere you want to go where you have interactive computing.
That idea is the ARPAnet. Licklider later returned to lead the IPTO in for two years. Packet switching The issue of connecting separate physical networks to form one logical network was the first of many problems.
Early networks used message switched systems that required rigid routing structures prone to single point of failure. Kleinrock subsequently developed the mathematical theory behind the performance of this technology building on his earlier work on queueing theory.
It provides better bandwidth utilization and response times than the traditional circuit-switching technology used for telephony, particularly on resource-limited interconnection links.
Its current best-selling products are the Microsoft Windows operating system, Microsoft Office suite of productivity software, Xbox, a line of entertainment of games, music and . Since the Internet has tremendously impacted culture and commerce, including the rise of near instant communication by email, instant messaging, telephony (Voice over Internet Protocol or VoIP), two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. Increasing . Since the mids, the Internet has had a revolutionary impact on culture, commerce, and technology, including the rise of near-instant communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social .
NPL network Following discussions with J. Licklider, Donald Davies became interested in data communications for computer networks. The following year, he described the use of an "Interface computer" to act as a router. We typed the O, and we asked, "Do you see the O.
Yet a revolution had begun" Stamp of Azerbaijan, Bythe number of hosts had grown towith a new host being added approximately every twenty days.
These early years were documented in the film Computer Networks: The Heralds of Resource Sharing. For various political reasons, European developers were concerned with developing the X. Over the next several years in addition to host to host interactive connections the network was enhanced to support terminal to host connections, host to host batch connections remote job submission, remote printing, batch file transferinteractive file transfer, gateways to the Tymnet and Telenet public data networksX.
First demonstrated init was developed to explore alternatives to the early ARPANET design and to support network research generally.
It was the first network to make the hosts responsible for reliable delivery of data, rather than the network itself, using unreliable datagrams and associated end-to-end protocol mechanisms. Clarkein which he describes a future of ubiquitous networked personal computers.
While using packet switchingX.Delphi was the first national commercial online service to offer Internet access to its subscribers. It opened up an email connection in July and full Internet service in November All pretenses of limitations on commercial use disappeared in May when the National Science Foundation ended its sponsorship of the Internet .

But, not all of us know about many interesting facts about the internet and its usage. Here, we bring to you a list of 29 most interesting internet . Development of the Internet and the World Wide Web The recent growth of the Internet and the World Wide Web makes it appear that the world is witnessing the arrival of a completely new technology.
The first workable prototype of the Internet came in the late s with the creation of ARPANET, or the Advanced Research Projects Agency Network. Beginnings of the Commercial Internet From the late s on, the importance of the connectivity provided by the NSF and its educational alliances cannot be overstated.
There was no commercial viability or the Internet at this time, but it continued to grow at an incredible rate.
