Which one of the following is not a definition of error ?
It refers to a condition that causes a system to fail.
IEEE terminology gives several meanings of 'error': the difference between a computed and a true value, the difference between actual and correct output, and a human mistake that introduces a defect.
A condition that causes a system to fail is the definition of a fault (defect), not of an error.
So the statement about a condition causing failure does not define error.
Hence, It refers to a condition that causes a system to fail.
