error on Wiktionary

TLDR: An error in computing refers to an issue that arises when a system or program encounters unexpected or incorrect conditions, leading to failure in execution or incorrect results. Errors can occur due to bugs in software, hardware malfunctions, or user input that the system cannot process. Identifying and resolving errors is critical to maintaining the reliability and security of systems.

https://en.wikipedia.org/wiki/Error

Errors are categorized into various types, including syntax errors, runtime errors, and logical errors. For example, a syntax error might result from improper use of a programming language's grammar, while runtime errors like null pointer exceptions occur during execution when unexpected conditions arise. Proper error-handling mechanisms, such as try-catch blocks in Java or Python, are essential to mitigate the impact of these errors.

Secure error handling is a key component of application security. Misconfigured or verbose error messages can expose sensitive system details, such as stack traces, class names, or database paths, which attackers could exploit. Implementing generic error messages for users while logging detailed issues internally aligns with OWASP Top Ten's principles and enhances overall system robustness.

Snippet from Wikipedia: Error

An error (from the Latin errāre, meaning 'to wander') is an inaccurate or incorrect action, thought, or judgement.

In statistics, "error" refers to the difference between the value which has been computed and the correct value. An error could result in failure or in a deviation from the intended performance or behavior.
