Which statement best describes Bluetooth?

• A. Bluetooth is a wired networking standard
• B. Bluetooth operates over long distances
• C. Bluetooth is a wireless communication standard
• D. Bluetooth uses fibre optic cables

Answer: (C)

Bluetooth is a wireless communication standard used to connect devices over short distances. It uses radio waves instead of cables, making it suitable for creating small personal area networks like headphones connecting to phones or speakers to laptops. It operates in the 2.4 GHz spectrum and is designed for low power consumption, which fits close-range, everyday connections. It isn’t meant for long-distance links, so it wouldn’t be described as a system for long-range communication. It also doesn’t rely on fibre optic cables, which carry data as light in glass or plastic fibers. So the strongest description is that Bluetooth is a wireless communication standard.
