Internet is a network of networks that allows the decentralized interconnection of computers through a set of protocols called TCP / IP. It had its origins in 1969, when an agency of the Defense Department of the USA began to look for alternatives to an eventual atomic war that could cut people off.

Three years later the first public demonstration of the system devised was carried out, thanks to California and one of Utah managed to establish a connection known as ARPANET (Advanced Research Projects Agency Network).

Computer network

The Internet is often defined as a network of networks.

Differences between the Internet and the World Wide Web

Contrary to what is usually thought, Internet and the world Wide Web they are not synonymous. The WWW is an information system developed in 1989 for Tim Berners Lee Y Robert Cailliau. This service allows access to information that is linked through the protocol HTTP (HyperText Transfer Protocol).

Other services and protocols available in the network of networks are remote access to computers known as Telnet, the file transfer system FTP, the email (POP Y SMTP), file sharing P2P and online conversations or chats.

A revolution on a global scale

The development of Internet has far exceeded any forecast and constituted a true revolution on the society modern. The system became a mainstay of communications, entertainment and commerce in every corner of the planet.

Statistics indicate that, in 2006, the Internet users (known as netizens) exceeded 1100 million people. This figure was expected to double in the following decade, driven by the overcrowding of high-speed accesses. velocity (broadband), but the results exceeded expectations: by 2020, the number of Internet users exceeds 4.54 billion, almost 60 percent of the world’s population and more than double what had been anticipated.

Globalization

The Internet makes it possible for millions of people to communicate instantly.

Among the reasons why the Internet has reached such a degree of massification is the creation of smartphones, which today we simply call mobile phones because they are already the norm, but which at the time represented a revolution at a technological and social level. While the first mobile phones simply allowed us to make calls and send text messages of a reduced length, little by little companies were adding functionalities that expanded them to become small computers, with spectacular screens and sound quality impossible for their size .

The growth of the Internet

At first, the Internet was overwhelming for people outside the world of computing, and so it attracted the almost exclusive interest of computer lovers. technology. Like all changes, it did not happen overnight, but it was thanks to the early adopters of this tool to communicate remotely that the Internet was promoted little by little, showing more and more attractive features for skeptics.

The chat It was undoubtedly one of its fundamental pillars, to the point that many of today’s users approached the Internet exclusively to take advantage of it. While chat rooms are not as popular today, they were hugely successful in the 1990s. It should be noted that the possibilities they offer are not entirely comparable with those of current instant messaging systems since they allow you to meet people spontaneously while sorted by location, interests, ages and more categories.

In short, we can say that the Internet began as a curiosity for those who wanted to expand the possibilities of their computers but in a matter of a few years it became the most used tool in everyday life to perform or complement almost all our activities, from communications to work, through entertainment.
