Internet emerges at the end of the sixties in the USA. In its infancy had a scientific use only in the nineties and their use is widespread.

The emergence of the Internet has made a great revolution in the world of technology. It has become a tool for work, leisure and entertainment, ultimately, a way of life.

Origins

The Internet was born after several investigations carried out by a group of scientists and non-governmental agency ARPA (Advanced Research Projects Agency) during the Cold War.

The main objective of the research was to get a connection among several computers. With it, researchers could share resources from different parts of the country.

The biggest drawback was that there was every researcher should have a computer in his home and a terminal to be able to communicate over a network, which is expensive.

The solution to the problem was to remove the terminal and use computers as a server. It is connected in a network and were located at strategic points.

Evolution

One of the group's ARPA researchers created a communicaion network called ARPANET consisting of a system of interconnected networks.

This network has grown rapidly to become absorbed by the NSF (National Science Foundation). Since then creates a new computer network for scientific purposes and academics called NSFNET.

NSFNET became a large network with a large number of servers (100,000), thanks to its merger with ARPANET appears the word internet (International Network) and with it the opening of the network to non-scientific purposes.

In 1993, due to the appearance of browser World Wide Web (WWW) and the boom in personal computers in the home, the Internet began to be known worldwide and to be used for all kinds of purposes.

In 2000, held the so-called bubble effect, also known as the Internet boom. Thousands of companies, after knowing the great potential of the network, began investing large sums of money.

With this investment bubble began to swell up in 2001, after realizing that the results did not match the high investment, the bubble burst, leading to the bankruptcy of many Internet companies.

In Spain

The key date from the Internet in Spain is 1995 and that is when InfoVía born, better known as the Spanish Internet. This year is also the boom of suppliers, as a plus offering Internet services to users. The latter accounted for 0.3% of the total global Internet users.

The main reason for this low number of users was the price of the connection, as was done via a modem and paid for the use of the phone and connection. Another cause was the cost of computers, which are considered as luxury items.

In 1999 appeared on the market new companies offering Internet services when he is not charged the connection. Since then, the number of users has increased dramatically.

Currently, there is a type of DSL connection where it is not paid by either the connection or for the time they use the line. This connection has a fixed cost of use, and provides unlimited more speed.

The emergence of ADSL and the decline in the price of computers has brought the number of regular users has increased to 7 million or so.
