Internet it is a vast virtual world in which we all have a space. It is so popular that we should know its origin by knowing what it is, what it is used for and how it works Arpanet? - Internet history.

The use of the Internet is beyond what we can imagine. Both for purposes personal than commercial, the network maintains communication around the world, which has changed dramatically. Have questions like what is the World Wide Web or Arpanet and what is it for , here we will tell you a little about these technologies that have revolutionized the world.



What is Arpanet, what is it used for and how does it work? - Internet history

The internet is not a new thing. Five decades ago it had a particular origin that goes back to the United States military through a project called the Arpanet. Next, we will show you the details about the true origin of what we now call «internet».

What is Arpanet?

Arpanet stands for Advanced Research Projects Agency. This project was founded by the United States Department of Defense in 1958. In 1962, the project took a clearer course when John Licklider ha proposed the idea of ​​creating a network to communicate users through their computers.

Subsequently, the University of California developed the first node and, on November 21, 1969, he successfully sent the first message to a Stanford University SDS 940 computer.

What is the purpose of Arpanet?

Arpanet is used to create secure communication between the different research bases of the been through a computer network. Therefore, the purpose of this project is aimed at the administrative and security area.


How does the Arpanet work?

Arpanet works by connecting a network of nodes located in different locations. Initially the connection was made via the NLS system which featured a primary version of the hypertext. A few years later, in 1981, the TCP / IP protocol was born and in this way Arpanet marks its evolution.


This protocol was very important for the evolution of the Internet and the rest of the networks as we know them today, if you want to know what the TCP / IP protocol is and how it works, you can visit the previous guide in which we talked about it more thorough.

History of the Internet

The Internet was born in the military field through the evolution of the Arpanet project. In 1958, the United States Department of Defense tried to achieve direct and secure communication between state agencies. Thus was born the Arpa project.

Arpa was the first technological step for the creation of the network of networks. This project had a large budget and two hundred specialists who had been dedicated for more than a decade to achieving its goal: to communicate users over a computer network.

Thanks to the work and constant research of the Massachusetts Institute of Technology, the Rand Corporation and the National Physics Laboratory, a plan was published to create a computer network called Arpanet, which had a network of twenty-three connected points for the year 1971.

Arpanet in Education

Arpanet has also established itself at the university level by creating a network between the Universities of California and Stanford. Since then, the technological link between education and the state has remained over the years.


In 1972 Arpanet proved itself effective by creating a network of forty connected points and located in different locations. Indeed, more research has been developed and new networks have emerged. Ten years later, Arpanet made a change from the NCP protocol to TCP / IP and thus the Internet or the international network was born and subsequently new protocols such as IPv6 would emerge, a new proposal with great advantages. If you want to know more about this new protocol, we can tell you what the IPv6 protocol is and how it works.



Now that you know the history of the Internet, it is important to clarify the term "Network" in so you can appreciate the designation of 'network of networks'.

What is a network?

A network is a set of computers interconnected to be able to share resources, applications, files of different formats and devices. In every network there must be a server which manages the devices and client or the rest of the computers that make up the network.


Now that you know the concept of a network, imagine a cluster of networks with their own services in all places on earth; this is the internet .   Among its services, e-mail, web pages and file transfer protocols stand out.

Web pages, e-mails and the different Internet protocols are essential, but have you ever wondered what they are and what are the Internet IP protocols? Of course, we invite you to inform yourself through the previous guide, in order to better understand everything we discuss in this article.
