CompTIA Network+ (N10-007) — Question 442
Which of the following communication media can carry many voice, data, and video channels simultaneously over multiple frequencies?
Answer options
- A. Broadband
- B. Baseband
- C. Analog modem
- D. CSMA
Correct answer: A
Explanation
Broadband is designed to handle multiple channels of voice, data, and video simultaneously, making it the correct answer. Baseband, on the other hand, transmits data over a single channel and is not suitable for multiple simultaneous transmissions. An Analog modem is a device used for converting digital signals to analog for transmission and does not inherently support multiple channels. CSMA is a network protocol for managing access to a shared communication medium, not a type of transmission medium itself.
