What is MILNET? - Definition from Techopedia
ARPANET: Experimental computer network founded by the Advanced Research Projects Its initial purpose was to link computers at Pentagon-funded research . In , ARPANET was divided into two parts, MILNET, to be used by military . In computer networking, MILNET (Military Network) was the name given to the part of the ARPANET internetwork designated for unclassified United States Department of Defense traffic. MILNET was physically separated from the ARPANET in Special pages · Permanent link · Page information · Wikidata item · Cite this.

By the s, a system called SAGE Semi-Automatic Ground Environment had already been built and was using computers to track incoming enemy aircraft and to coordinate military response.
According to Naughton, his brief two-year stint at the organization seeded everything that was to follow. But many of those involved said that the agency was far from being a restrictive militaristic environment and that it gave them free rein to try out radical ideas.
As a result, ARPA was the birthplace not only of computer networks and the Internet but also of computer graphicsparallel processing, computer flight simulation, and other key achievements.
He could watch as computers at all three remote facilities came alive with activity, connecting local users. Time-shared computers allowed people to exchange messages and share files. Through the computers, people could learn about each other. Interactive communities formed around the machines. Taylor also decided that it made no sense to require three teletype machines just to communicate with three incompatible computer systems.
It would be much more efficient if the three were merged into one, with a single computer-language protocol that could allow any terminal to communicate with any other terminal. There, plans were announced for building a computer network that would link 16 ARPA-sponsored universities and research centers across the United States.
According to Charles M. Herzfeld, the former director of ARPA, Taylor and his colleagues wanted to see if they could link computers and researchers together. It began with a thunderclap: It was the first inkling the public ever had about the potential of networked digital computing, and it attracted other researchers to the cause.
A packet of data ARPANET arose from a desire to share information over great distances without the need for dedicated phone connections between each computer on a network. Baran was instructed to come up with a plan for a computer communications network that could survive nuclear attack and continue functioning.
To illustrate in more recent terms: They do not all follow the same route and do not even need to travel in proper sequential order. It had been designed to manage communication host-to-host within the same network. To build a true open reliable and dynamic network of networks what was needed was a new general protocol.
The IP is a critical part of our daily Internet experience: The foundations for a worldwide network were laid, and the doors were wide open for anyone to join in. By then there were already 57 nodes in the network. The larger it grew, the more difficult it was to determine who was actually using it. The DCA began to worry. The mix of fast growth rate and lack of control could potentially become a serious issue for national security. The DCA, trying to control the situation, issued a series of warnings against any unauthorised access and use of the network.
By the early s, the network was essentially an open access area for both authorised and non-authorised users. This situation was made worse by the drastic drop in computer prices. With the potential number of machines capable of connecting to the network increasing constantly, the concern over its vulnerability rose to new heights.
The hit film, War Gamesabout a young computer whiz who manages to connect to the super computer at NORAD and almost start World Word III from his bedroom, perfectly captured the mood of the militaries towards the network.
But it was also being picked up by a growing number of other communities and networks. By then, the network - no longer the private enclave of computer scientists or militaries - had become the Internet, a new galaxy of communication ready to be fully explored and populated. Still, numbers can sometimes be deceptive, as well as frustratingly confusing for the non-expert reader.
What hides beneath their dry technicality is a simple fact: For a growing number of users, a mere minute of life on the Internet is to be part, simultaneously, of an endless stream of shared experiences that include, among other things, watching overhours of video, being exposed to 10 million adverts, playing nearly 32, hours of music and sending and receiving over million emails. Albeit at different levels of participation, the lives of almost half of the world population are increasingly shaped by this expanding communication galaxy.
How the Internet was born: from the ARPANET to the Internet
We use the global network almost for everything. But there is much more than this. The expansion of the Internet is deeply entangled with the sphere of politics. The more people embrace this new age of communicative abundancethe more it affects the way in which we exercise our political will in this world.
