Which of the following is not a communication media
Correct answer: D. Modem
- A. Twisted pair
- B. UTP (Unshielded Twisted Pair)
- C. Microwave
- D. Modem
Explanation
A modem (modulator-demodulator) is a device that converts digital signals from a computer into analog signals that can be transmitted over a physical medium, such as a telephone line or cable. It also converts incoming analog signals back into digital signals that the computer can understand While modems are essential components in communication systems, they are not considered a communication media themselves. They modulate and demodulate signals to enable data transmission through existing communication media such as coaxial cables or telephone lines
