Ever since inventions like the telephone and the telegraph, the internet has begun to evolve. Unlike inventions like the airplane and the light bulb, the internet was created as a group effort and wasn’t really created by one person. Instead, it has evolved over time starting with the NPL Network and the Arpanet. Both of these networks used packet switching. Packet switching is when you send a message, you break the message up into individual parts and then send them all. Then when they get to the destination, they automatically reassemble themselves. Then, they tested the Arpanet. The teams set up labs at UCLA and Stanford and tried to type letters to each other. The receiving team received just two letters before the system crashed, but nevertheless, a new era had begun.
Now, let’s fast forwards a bit. Now, the year is 1973. Although there are many little networks, there isn;t a large a large network encompassing a large enough area to be useful. So now, the little networks had to combine to make one big network. After the Arpanet was up and working, people began to realize that this small networks wasn’t big enough. Then in 1981, the NSF took a liking into the Arpanet network. So the government started giving some of it’s money into the Arpanet. The Arpanet would then eventually be renamed into the NSFNET. The NSFNET first had a network speed of 56kbit/s speed. This was too slow and the system would eventually get overloaded. So the system was upgraded to 1.5Mbit/s. Finally, the NSFNET was upgraded to 45MBit/s. The NSFNET had the ability to connect university and college campus networks to a regional network.
In conclusion, during the mid to late 1900s, many new discoveries were made to contribute to the evolution of technology like the Arpanet and the NSFNET. In the next part, we will progress more to the 21st century and how the internet in the 1990s really evolved into the internet that we know today.
