While the Internet’s origins can be traced to the ARPANET of the late 1960s, that was a single, closed network. Internetworking made its formal debut in 1976, when SRI established the first connection between two dissimilar networks. SRI connected the wired ARPANET with SRI’s wireless packet radio network, the world’s first mobile digital radio network. Then in 1977, the first connection was made across three dissimilar networks. This connection is considered to be the first true Internet connection. SRI played a major role in this critical milestone in the development of the modern Internet and wireless networking, both of which have had an immeasurable impact on how the world learns, works, shares and plays. 1970s COMMUNICATION FIRSTS INTERNET SEMINAL INNOVATIONS SOFTWARE Related innovations ARPANET Domain names and the Network Information Center OUR WORK Case studies Publications Timeline of innovation Areas of expertise Blog INSTITUTE Leadership Press room and media inquiries Compliance Privacy Policy CAREERS Job listings CONTACT SRI Ventures Our locations Headquarters 333 Ravenswood Ave Menlo Park, CA 94025 USA +1 (650) 859-2000 SUBSCRIBE TO OUR NEWSLETTER 日本支社 PRIVACY POLICY COOKIES DMCA ©2021 SRI INTERNATIONAL
