Arpanet

The first digital network that utilized packet switching, which is the transmission of data, regardless of content, in manageable chunks called packets. This was a revolutionary technology and ultimately led to the creation of the modern Internet. It was developed in the 1960s by the Defense Advanced Research Projects Agency.

(22.) The proliferation of networks started with NSFNET, a sort of clone of the second generation ARPANET used by NSF researchers, opening up connections to small commercial networks.
From a technical standpoint, the work on Project MAC and other time-sharing systems in the 1960s laid the groundwork for the ARPANet in the 1970s, the NSFNet in the 1980s, and the commercial Internet in the 1990s and beyond.
Posteriormente, la NSF (National Science Fundation) crea su propia red informatica llamada NSFNET, mas tarde absorbe a ARPANET, estableciendo una gran red con propositos cientificos y academicos, se crean nuevas redes de libre acceso que se unen a NSFNET, formando el embrion de lo que hoy conocemos como INTERNET.
The Internet evolved out of the National Science Foundation's NSFNET backbone, which was created in 1986 (and decommissioned in 1997) to provide universities all over the country with access to federally funded supercomputing centers located at five major universities.
