and effective communication



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.
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
The Pentagon Advanced Research Projects Agency (ARPA), created the first computer network, ARPAnet. During the first stage, the network had four computers connected
11 additional nodes were added.
40 computers were connected to the network. A group of specialists interested to communicate various types of computers established the Inter Networking Working Group
The document for Protocol Packet Network Internet Working was written; explaining how to resolve communications problems among different types of computers.
Protocol ideas began to be applied in a limited form
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.
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.



Ray Tomlinson sent the first email message
The pioneer network: ARPAnet that originated the internet stopped working
Tim Berners Lee (currently the director of World Wide Web Consortium), creates the World Wide Web, using three new resources: HTML (Hypertext Markup Language), HTTP (Hypertext Transfer Protocol) and a client program, called Web Browser
Mosaic (Web Browser), was created. It gained popularity very rapidly, but soon Netscape arises and becomes one of the most used internet programs at its peak.
