For what purpose is Bluetooth technology primarily used?

Bluetooth technology is primarily used for transmitting data over short distances, typically within a range of about 30 feet (9 meters). This wireless communication standard enables various devices, such as smartphones, headsets, speakers, and computers, to connect and communicate without the need for physical cables. The low power consumption and ease of use make Bluetooth ideal for applications where short-range connectivity is sufficient, such as streaming audio, transferring files, or connecting peripherals like keyboards and mice.

While other options address different aspects of technology or network functions, they do not align with Bluetooth's main purpose. For instance, Bluetooth is not designed for long-range connections, boosting Wi-Fi signals, or specifically encrypting data transmissions, although it can incorporate security features for data transmission. Thus, the focus on short-distance data transmission accurately reflects the primary function of Bluetooth technology.
