During the Cold War, the United States needed a way to network computers to send information. In the 1950's, no one had personal computers. All the computers were massive computers contained in entire rooms. The U.S. neeeded a way to connect these. So, the military created ARPANET. Several other networks grew from there.
In the 1980's, NASA developed the IP address system, which helped lead to what we now consider to be the internet. The internet as we know it really took off between 1989 and 1993, which helped prove that the United States was more innovative than the fledgling Soviet Union.
1. How is this related to either the military or NASA?
2. How would the world be different if this hadn't been invented?
