INTERNET HISTORY

In 1994 RACSA inaugurated the commercial Internet service, to expand the technological and information possibilities between companies, facilitate access and allow the rapid exchange of updated information.

Ten years ago, a new challenge was started, which consisted of expanding the service to the personal and residential sector.

Since its inception to date, the growth of the Internet service in Costa Rica has experienced a constant growth of more than 10% per year, facilitating immediate reach and penetration to the market for information and service providers towards potential clients. All, in a very dynamic and cost efficient way.

At RACSA we continuously develop projects associated to the Internet allowing customers to have value-added services according to the needs of the country’s productive sectors, as well as the interest of the residential sector. This is because we want to be the technological bridge between content providers and their customers.

Late 50's
At the height of the Cold War between the United States of America and the Soviet Union, the US Department of Defense began to worry about what could happen to their national communication system if nuclear war broke out.
1962
A US government researcher, Paul Baran, proposed a communications system using computers connected in a decentralized network, so that if one or several important nodes were destroyed, the others could communicate with each other, without any inconvenience
1969
The Pentagon Advanced Research Projects Agency (ARPA), created the first computer network, ARPAnet. During the first stage, the network had four computers connected
1971
11 additional nodes were added.
1972
40 computers were connected to the network. A group of specialists interested to communicate various types of computers established the Inter Networking Working Group
1974
The document for Protocol Packet Network Internet Working was written; explaining how to resolve communications problems among different types of computers.
1978
Protocol ideas began to be applied in a limited form
1982
All of the ideas were finally applied thoroughly, it was called Transmition Control Protocol – Internet Protocol (TCP-IP). As of this year the word internet began to be used.
1987
La National Science Foundation (NSF) creates NSFnet, a high efficiency network capable to connect 7 networks with 5 super computer centers, to provide access to the researchers located in different parts of the US territory. With this new network they were able to increase data transfer speed from 56 kbps to 1.5 Mbps.
