What is the primary function of Bluetooth technology?

The primary function of Bluetooth technology is to enable short-distance wireless communication between devices. This functionality allows various devices, such as smartphones, tablets, laptops, and other peripherals, to connect and exchange data without the need for physical cables or complex setups. Bluetooth operates typically within a range of about 10 meters (33 feet), making it ideal for situations where devices need to communicate in close proximity. This technology is widely used for tasks such as connecting headphones, transferring files between devices, syncing information, and enabling functionalities like wireless printing and gaming.

Other options, while related to technology and communication, do not accurately represent Bluetooth's primary purpose. For instance, encryption of financial transactions falls under security protocols rather than the specific capabilities of Bluetooth itself. High-speed internet access is associated with technologies like Wi-Fi and cellular networks that provide broader and faster connectivity over larger distances. Long-distance data transmission, meanwhile, is handled by other technologies designed for that scope, such as cellular networks or satellite communication, rather than Bluetooth, which is specifically designed for short-range applications.
