What is a common application of Bluetooth technology?

1. Personal area networking

2. Long-range internet access

3. Streaming HD video

4. Wired data transmission

The correct answer is: Personal area networking

Bluetooth technology is commonly applied in personal area networking, which allows devices to connect and communicate within a short range, typically up to about 30 feet. This application is widely utilized for enabling seamless connections between peripherals and devices, such as connecting a smartphone to wireless headphones, linking a computer to a wireless keyboard or mouse, and transferring files between devices. Personal area networking is characterized by its low power consumption and ease of use, making it ideal for scenarios where convenience and short-distance communication are necessary. The other options do not align with the primary uses of Bluetooth technology. Long-range internet access typically relies on other technologies, such as Wi-Fi or cellular networks. Streaming HD video generally requires higher bandwidth than what Bluetooth can provide; instead, technologies like Wi-Fi or HDMI connections are preferred. Wired data transmission is contrary to the wireless capabilities of Bluetooth and is typically achieved through cables and ports, such as USB. Thus, personal area networking accurately encapsulates the core function of Bluetooth technology in practical applications.
