Which of the following is not classified as a medium of wireless communication?

• A. Bluetooth
• B. FM/AM Radio
• C. Fiber Optic
• D. 2.4 GHz WiFi

Answer: (C)

Fiber optic is not classified as a medium of wireless communication because it relies on light signals transmitted through glass or plastic fibers to convey information. This method of communication is inherently wired, as it requires physical cables to connect the transmitting and receiving ends. In contrast, the other options, such as Bluetooth, FM/AM Radio, and 2.4 GHz WiFi, are all forms of wireless communication that transmit data through radio waves or electromagnetic signals without the need for physical connections between devices. These technologies enable devices to communicate over various distances and are fundamental to modern wireless networking and communication systems. Thus, fiber optic stands out as the only wired medium in the list provided.
