Q. The residual error rate is the
✅ Correct Answer: (D)
Probability that one or more errors will be undetected when an error detection scheme is used
Explanation:
Residual error rate refers to the likelihood that errors remain undetected after applying an error detection method.
- It measures how effective an error detection mechanism is in catching errors; ideally, this rate should be very low.
Other options describe different concepts:
- (A) describes the probability of detecting errors (not residual).
- (B) is unrelated to error rates.
- (C) is a measure of bit error rate over time, not residual error rate.
