Bluetooth is a wireless communication technology that allows devices to connect and exchange data over short distances. It works by using radio waves to establish a secure and low-power connection between two or more Bluetooth-enabled devices, such as smartphones, laptops, headphones, or speakers. Bluetooth technology is widely used for wireless audio streaming, file transfer (AirDrop), and device control. For example, you can use Bluetooth to connect your smartphone to a wireless speaker and play music, or connect your mobile phone to a hands-free car kit. Bluetooth is a convenient and versatile technology that eliminates the need for wires or cables, and it has become a standard feature in many modern devices.
