The internet started out as a venture undertaken by the United States Department of Defence called the ARPANET or the Advanced Research Projects Agency Network. It was invented for sharing data between a number of nodes spaced over larger distances.

With the introduction of packet radio, connecting a mobile terminal to a pc network grew to become feasible. However, time-sharing techniques have been then still too massive, unwieldy, and costly to be cellular or even to exist exterior a local weather-controlled computing environment. A sturdy motivation thus existed to connect the packet radio community to ARPANET so as to permit cellular customers with simple terminals to access the time-sharing techniques for which they had authorization. Similarly, the packet satellite community was utilized by DARPA to link the United States with satellite tv for pc terminals serving the United Kingdom, Norway, Germany, and Italy. These terminals, nevertheless, had to be connected to different networks in European international locations to be able to reach the tip customers.
