🧠 Explanation:

Bluetooth is a wireless technology embedded in electronic devices to exchange data over short distances, typically up to 10 meters. The term “Bluetooth” is a proper noun, naming this specific standard. It allows devices like smartphones, laptops, headphones, and printers to communicate without physical cables.
