In the year 1957, the Soviet Union launched Sputnik 1 as the world’s first artificial satellite. In response to this event, the United States established the Advanced Research Projects Agency (ARPA) in 1958 to promote advanced technologies for national security under the Department of Defense.
Packet Switching
Packet switching is one of the significant innovations that made the inception of the internet possible.
The concept of “Packet Switching” is about breaking data into small packets that could independently travel across networks and again reassembled at their destination. However, this became the support for the inception of the modern internet.
2. ARPANET: The Advent of Internet (1969)
In 1969, ARPA launched ARPANET, which was the first operational packet switching network. However, it connected 4 major institutions across the United States. It includes:
- University of California- Los Angeles
- Stanford Research Institute- California
- University of California- Santa Barbara
- University of Utah- Utah
The main goal of ARPANET was to allow researchers to share resources and communicate effectively
The first internet message sent
On October 29th, 1969, researchers attempted to send the word “LOGIN” over ARPANET from UCLA to Stanford Research Institute. Unfortunately, the system crashed after transmitting the first two letters. i.e., LO
Despite the system crash and failure to transmit the complete word over ARPANET, yet this marked the “birth of the Internet”.
