In recent class presentations, I learned a lot about the involvement of technology, especially Bluetooth. I use Bluetooth every day, whether that be connecting to my headphones, car, speaker, or using Airdrop. I never gave much thought to how Bluetooth works and why it is called Bluetooth. The presentation was very insightful and informative.
The name "Bluetooth" dates back to the viking king "King Harald". He was known for uniting Denmark and Norway. King Harald got the nickname Bluetooth because he had a rotting dark blue tooth. During a meeting, three industrial leaders Intel, Ericsson, and Nokia were discussing how they wanted to invent a short range, connection technology that could connect different products. In the meeting, Jim Kardach suggested the story of King Harald because he liked the story as well and they both wanted to unite something. Bluetooth was supposed to be a temporary name. The inventors had other names like RadioWave or PAN, but those weren't as popular as Bluetooth. The name spread throughout the world.
Bluetooth is used by communicating through 79 different frequencies through low-powered radio waves on a frequency band around 2.4GHZ. This means that when two devices are paired through Bluetooth, they randomly pick up one of the 79 different frequency waves to make some sort of connection. Once the devices are connected, they bounce to different frequencies at a fast pace. When the devices are too far apart, the connection gets disconnected which is the only downside. The benefits of having Bluetooth are photos, videos, data, and other things can be easily transferred with devices without having to send via message or email. Larger files can be moved, it is wireless, consumes little energy, and has less interference.
Overall the presentation was presented well. I learned so much about the technology I use every day. It is important to understand what we are using in our daily lives.
