Is V.21 faster than V.17?

Is V.21 faster than V.17?

• A. Yes
• B. No
• C. Only in specific situations
• D. It varies by manufacturer

Answer: (B)

V.21 is actually a slower protocol compared to V.17. V.21, which operates at a baud rate of 300 bps, is primarily designed for simple data transmission and can be used for applications like faxing and low-speed data communication. In contrast, V.17 operates at a baud rate of up to 14,400 bps, providing much faster data transmission suitable for modern fax machines and other data-intensive applications. The primary function of V.17 is to facilitate high-speed fax transmission, supporting a range of features that enhance the overall efficiency and quality of the communication process. Therefore, when comparing the two, V.17 is indeed faster than V.21, making it the more efficient choice for transmitting data quickly.
