What is it, what is it for and how does the Arpanet work? – Internet history

Internet is a vast virtual world where we all have a space. It is so popular that we should know its origin by knowing what is it, what is it for and how does the Arpanet work? – Internet history.

The use of the internet goes beyond what we can imagine. Whether for personal or commercial purposes, the network maintains communication throughout the world, which has changed remarkably. You have questions like what the World Wide Web or the Arpanet is and what it is for , here we will tell you a little about these technologies that revolutionized the world.

What is it, what is it for and how does the Arpanet work? – Internet history

The Internet is not a new element. Five decades ago it had a particular origin that went back to the United States military through a project called Arpanet. Next, we will show you details about the real origin of what we now call the “internet”.

What is Arpanet?

Arpanet is the acronym 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 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, they successfully sent the first message to an SDS 940 computer at Stanford University.

What is Arpanet for?

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

How does Arpanet work?

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

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

Internet history

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

Arpa was the first technological step for the creation of the network of networks. This project had a high budget and two hundred specialists who dedicated themselves for more than a decade to achieve its objective: to communicate users through a computer network.

Thanks to the constant work and 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 points connected for the year 1971.

Arpanet in Education

Arpanet 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 to be effective by creating a network of forty points connected and located in different locations. Indeed, more research was developed and new networks emerged. Ten years later, Arpanet made a change from the NCP protocol to TCP / IP and thus the Internet or the International net emerged and later new protocols such as IPv6 would emerge, a new proposal with great advantages. If you want to learn 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” so that you can appreciate the designation of “network of networks.”

What is a network?

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

Now that you know the concept of a network, just imagine a cluster of networks with their own services in all places on earth; this is the internet network .   From the set of own 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 is and what are IP Internet protocols used for ? Certainly, we invite you to inform yourself about it through the previous guide, so that you better understand everything that we discuss in this article.
