Bluetooth is the name of a wireless communication technology(wireless) that interconnects and allows the transmission of data between computers, cell phones, digital cameras and other devices through radio waves.
It was created in 1994 by the Swedish company Ericsson, which wanted a low-cost technology that would allow communications between cell phones and accessories without the need for cables.
A very important application of bluetooth is wireless communication between cell phones and headphones. Those who are driving a vehicle have the advantage of not having to use their hands to answer the cell phone or having headphones connected by wires.
Cars that have this technology work with hands-free systems. The driver turns on the Bluetooth on the cell phone and when there is a call, the speakerphone system is activated.
The use of Bluetooth technology is also applied to keyboards, mice and printers, which work without the need for cables connected to the computer.
Origin of Bluetooth name
The Bluetooth name is reportedly chosen in honor of the King of Denmark and Norway Harald Blåtand (Bluetooth is a version English for the original Scandinavian name) which during his reign (in the 10th century) managed to unify tribes of countries Scandinavians. The analogy is a reference to technology that also unites communication protocols into a universal standard.
