Which technology is used for wireless networking?

• A. Bluetooth
• B. Ethernet
• C. USB
• D. Fiber Optics

Answer: (A)

Bluetooth is a wireless technology that enables communication between devices over short distances. It operates in the 2.4 GHz frequency range and is primarily used for connecting peripherals such as headphones, keyboards, mice, and other handheld devices without the need for cables. This makes it ideal for personal area networks and is commonly found in consumer electronics. On the other hand, Ethernet, USB, and fiber optics are all associated with wired connections. Ethernet is a standard for wired networking that uses cables to connect devices in local area networks (LANs). USB (Universal Serial Bus) is a wired interface used primarily for connecting peripherals to computers. Fiber optics refers to the use of light to transmit data through glass or plastic fibers, and while it provides high-speed data transmission, it also requires physical cabling. Hence, Bluetooth is the right answer as it explicitly relates to wireless networking technology.
