Software Robustness Explained

The question asks for the term describing software's ability to handle unexpected problems.

Robustness is the quality attribute that defines the extent to which software can withstand errors, invalid inputs, or stressful environmental conditions and continue to function correctly or fail gracefully.

Understanding Key Software Qualities

Let's clarify the terms:

• Accuracy: Refers to how closely the software's output matches the true or expected values. It doesn't directly address handling unexpected issues.
• Reliability: Measures the probability of failure-free operation for a specified period. While related, it focuses on the likelihood of failure, not the *manner* of handling problems.
• Correctness: Means the software behaves exactly as specified in the requirements. Robustness is a facet of correctness, specifically under non-ideal conditions.
• Robustness: Directly addresses the software's resilience and ability to manage unexpected situations, errors, or invalid data without crashing or producing completely incorrect results.

Therefore, the software's tolerance for unexpected problems is termed Robustness.
