error

n. a mistake a deviation from what is correct or specified by standard the difference between an observed or calculated value and the theoretical correct value, especially resulting from variations in measurement Computinga failure of software or hardware that produces an incorrect result or a failure in the system Lawa mistake in a court's opinion, judgment, or order

Notes

Error1 includes poor judgment in a decision or the belief that something false is true or the converse. Error2, 3 is generally relative. The degree to which something deviates from a standard or theoretical value is measured in terms of its accuracy. The ability of a system to measure the difference depends on the precision of the system.
