Which of the following is not an example of wireless communication?

Answer: Option C

Wireless Communication: Wireless communication is the transfer of information over a distance without the use of wires or physical conductors. It relies on electromagnetic waves to transmit signals.

Explanation: The question asks which option is NOT an example of wireless communication.

Option A: Wi-Fi: Wi-Fi is a popular wireless networking technology that uses radio waves to connect devices to a network. This is a clear example of wireless communication.

Option B: Mobiles: Mobile phones (cell phones) use radio waves to communicate with cell towers, enabling voice calls and data transmission. This is also a prime example of wireless communication.

Option C: Landline: A landline telephone system uses physical wires (copper cables) to transmit voice signals. This is fundamentally different from wireless communication, as it relies on a physical connection between the phone and the network.

Option D: Wireless Computer Parts: This refers to components like wireless keyboards, mice, and headsets that use radio frequencies or Bluetooth to communicate with a computer. This is wireless communication.

Correct Answer: Therefore, the correct answer is Option C: Landline, as it utilizes wired communication and not wireless technology.
