With this invention, I think my blog today ... First 
Although one might think that the Internet is something that has emerged in recent times, not so: 
Internet and has been with us a few decades. The early Internet
us back to the years 60. In the Cold War, the U.S. military create a system solely with the objective that in the unlikely event of a Russian attack, they could have access to military information from anywhere in the country. This network was established in 1969 and was called ARPANET.
ARPANET continued to grow and open to the world, and anyone with academic or research purposes could access the network. Military functions dissociated themselves from ARPANET and MILNET went to a new network created by the United States. The NSF (National Science Foundation) creates its own computer network called NSFNET, which later absorbed ARPANET, creating a large network with purposes científicos y académicos. El desarrollo de las redes fue abismal, y se 
crean nuevas redes de libre acceso que más tarde se unen a NSFNET, formando el embrión de lo que hoy conocemos como INTERNET. Ésta es una gran red internacional de ordenadores, una red de redes, que permite compartir recursos, es decir establecer una comunicación inmediata con cualquier parte del mundo para obtener información sobre algún tema que nos interesa.
Actualmente es casi imposible calcular los sitios web que existen y los servidores a los que tenemos acceso. Internet se ha desarrollado en esta última década mucho, y en parte es debido a los fines comerciales de las empresas. Internet ya no es la red de investigación military or what it was created, now the Internet is primarily a business, and this has been what has driven its development.
Email also known as e-mail, is a technological resource that allows us to communicate from anywhere in the world through Internet. In 1971 Ray Tomlinson, an engineer at Bolt Beranek and Newman firm hired by the U.S. government to build the Arpanet (the precursor to Internet), had the idea of \u200b\u200bcreating a system to send and receive messages across the network . Tomlinson had written a program for developers of Arpanet messages were left on shared computers (15 in the whole national network). Playing with other protocol to transfer files between machines scattered throughout the network, noted that together could be used to access all mailboxes. The text of the first message sent by e-mail was something like "QWERTYUIOP (random keystrokes on the keyboard because of evidence) by its inventor and sent through a program called SNDMSG he wrote.
