Discrete handshaking is typically used for distances ______.

• A. 50-100 feet
• B. 100-200 feet
• C. More than 200 feet
• D. Less than 50 feet

Answer: (D)

Discrete handshaking relies on simple on/off signals to coordinate data transfer, so it’s most reliable over short runs where noise, timing variations, and signal reflections are minimal. As distance increases, these factors can cause handshake signals to be misread or delayed, breaking synchronization. To maintain reliability, this method is kept for very short distances, typically less than 50 feet. For longer spans, more robust signaling or communication protocols are used to handle noise and timing more effectively.
