Which of the following is a key advantage of using Bluetooth technology?

The key advantage of using Bluetooth technology is its short-range connectivity with low power consumption. Bluetooth is designed for wireless communication between devices within a limited range, typically around 30 feet, making it ideal for applications such as connecting headphones to smartphones or linking various smart home devices. This short-range capability enhances security and minimizes the risk of unauthorized access to personal devices.

Moreover, Bluetooth's low power consumption allows devices to operate efficiently for longer periods without draining their batteries quickly, which is particularly beneficial for portable devices like wearables and Bluetooth accessories. This combination of short-range connectivity and efficient energy use distinguishes Bluetooth as a widely adopted technology for seamless personal area networking.

The other options present characteristics that are not inherent advantages of Bluetooth. For instance, while Bluetooth does offer some degree of compatibility, it is not universally compatible with all electronic devices, especially if they lack Bluetooth capabilities. Additionally, Bluetooth does not provide high bandwidth suitable for large data transfers; it is optimized for lower data rates, making it less suitable for heavy data tasks compared to other technologies. Lastly, while Bluetooth has some level of resistance to electronic interference, it is primarily designed for short-distance communication, making it a less critical feature compared to its low power consumption.
