Internet of Things (IoT) Practice Exam

Bluetooth technology is mainly used for?

1. Small devices with low bandwidth and small batteries

2. Small devices with high bandwidth and small batteries

3. Small devices with low bandwidth and large batteries

4. Large devices with low bandwidth and small batteries

The correct answer is: Small devices with low bandwidth and small batteries

Bluetooth technology is primarily designed for short-range communication between small, low-power devices. This makes it particularly suitable for applications where energy efficiency is important, as these devices often rely on small batteries to function over extended periods without frequent recharging or replacement. The context of low bandwidth is also significant; Bluetooth typically supports lower data rates, which is adequate for functions such as connecting wireless headsets, fitness trackers, and other IoT devices that don't require high-speed data transmission. The focus on small size and low energy consumption aligns perfectly with the objectives of Bluetooth technology. This combination of features makes Bluetooth ideal for peripherals and devices that need to communicate wirelessly while maintaining a long battery life. Moreover, its robustness in environments with potential interference further solidifies its place as the go-to technology for connecting small devices in everyday applications.
