Which of the following is a key feature of Bluetooth?

• A. Long-distance communication
• B. Secure connections through pairing
• C. Complex installation requirements
• D. High data transfer rates

Answer: (B)

A key feature of Bluetooth technology is its ability to establish secure connections through a process known as pairing. When two Bluetooth devices connect, they go through a pairing process where they exchange security keys to authenticate and encrypt the communication between them. This ensures that the data transmitted between the devices is secure and that unauthorized access is prevented. Bluetooth operates over a short-range, typically up to 100 meters for some devices, rather than facilitating long-distance communication. Additionally, Bluetooth devices are designed to be user-friendly, often requiring minimal installation procedures, making it straightforward for users to connect them without complex setup requirements. While Bluetooth can achieve respectable data transfer rates, they are not considered high when compared to other wireless technologies like Wi-Fi. Thus, the security through pairing stands as a defining characteristic of Bluetooth technology.
