I believe that many people will use Bluetooth every day, used to connect wireless headphones to listen to songs or transmit data, so do you know why it is called "Bluetooth"?
You only know that Huanglongjiang is full of Bluetooth, but do you know that you have used Bluetooth for so many years, why is it called Bluetooth?
Around the 10th century A.D., there was a Danish king in Northern Europe who unified Scandinavia, which was harassed by the Vikings at the time.
It is said that the king was nicknamed "buletooth" because of his blue teeth.
Time came to 1996, at this time, Intel, Nokia and other companies had their own set of short-range wireless communication technology, but due to the incompatibility of each protocol, not only was it inconvenient for consumers to use, but their products were not sold well.
So they decided to work together to develop a common set of transport protocols that would be mutually beneficial.
When it came time to name the protocol, the engineers of the two companies happened to be chatting together about European history, and then they were surprised to find that the unification protocol they were doing now was not what the Danish "Bluetooth" king used to do.
So they hit it off, and the Buletooth Bluetooth was born.
Seeing this, it is estimated that some netizens will joke that if our domestic mobile phones unify the charging agreement, will it be called "Qin Shi Huang Agreement" or "First Emperor/Ying Zheng Agreement".
However, I personally think it is more appropriate to call it "Zulong Agreement", after all, people use nicknames, not direct names.
Well, the above is the origin of the Bluetooth name, do you understand? Hurry up and collect or forward it to your relatives and friends~
