What is the most efficient method of data transmission over telephone lines?
Correct answer: A. Serial Transmission
- A. Serial Transmission
- B. Parallel Transmission
- C. Digital Transmission
- D. Hybrid Transmission
Explanation
The correct answer is (a) Serial Transmission. Telephone lines have limitations in bandwidth and are prone to noise interference. Serial transmission is more efficient in this context because it sends data one bit at a time, reducing the impact of noise and making better use of the limited bandwidth. It also requires fewer wires compared to parallel transmission, making it a more practical solution for telephone lines.
