To err, to stray, to mis take (take in error). The prefix "mis" added to verbs means wrong (mistake, mismanage, mislay)
Machines do not err. Nor do machines get things right. When we say a machine performs correctly, it means it performed to our expectations. When we say a machine produced an error, we mean that it did something we did not expect or plan for.
Computers, being machines, do not err. A typical computer follows a process laid out via programming. A computer cannot get things right. It is the programmer who gets things right and then programs the computer functions in an expected and desired way. When a program produces an unexpected or anomalous outcome, we call these bugs*. [after the first bug presumably. A moth that got into the hardware.] But what is actually happening is either a program made a mistake either of data entry or conceptually about how a program was or was not going to function, and when an un-anticipated condition occurs in the program, the program operates in a way the programmer did not conceive.
When we think of human beings making mistakes, we mean that they did something, but not what was desired or expected. the person (or animal) can change their behavior or thought process to produce a different outcome. But mistakes in human beings are not computational programming errors. There is no program running a person.
When learning a new skill, a person may try doing both the right action and the wrong action to get a sense of how they are different. Learning to swim, or learning to dance require body adjustments. In that process you can try different body motions to see what effects these motions have. If one of the motions is considered an error, you can still do it.
A computer cannot do an error. A computer cannot intentionally make an error or avoid an error. A computer executes a program, a computation.
Organisms do not run programs. Organisms, from insects to human beings, do engage in repetitive behavior, but repetitive behavior is not a program or a computation, or a mechanism. When we see a creature repeat a behavior over and over without producing an outcome the creatures "wishes" to obtain, we would say that creature is unable to adapt to it's situation, or that a person or creature is unable or incapable of perform an action. We do not say there is a programming flaw in the creature.
The idea of errors and mistakes require an expression of value and an expression of meaning. Often with errors, the meaning is implicit and it is only the value component of an action or experience that we measure. Meaning is intrinsic create value representations. For example 2+2 = five is an error of addition. We refer to the fact that 5 is the wrong value. What is hidden is the meaning of addition. In computation, the meaning is inherent in the programmer's representation making, and the computer only deals with values.
Here is a more glaring example: We do not value automobile tires in the same way we value entertaining television. The values for tires and tv. have very different meanings. We would say they are "apples and oranges" because the values exist in different contexts and the contexts have different meanings. Just as apples and oranges are not the same kinds of fruit, tires and television are not the same kinds of materials. But in your brain, or in a computer system, tires and television occupy or are made of, the exact same things.
Televisions programs and tires are made of neural and chemical pathways and signals in your brain. And in a computer AI, they are made of binary data and processor functions. How do you, with you brain, distinguish tires from tv? How does a computer AI go about distinguishing them? We say they are contextually different, but that means what? What is context?
If you mistake a tire for a television character what has happened? (What about the Michelin Man?) If a computer mistakes tv for tires we see it as a failure of programming or a failure of the algorithms it has been programmed with. but if a human errs in some major way we see it as a failure in the brain... or perhaps demonic possession.

We call perceptual errors, errors only because they do not comport with out own perceptions. But our perceptions are correct in what context? We do not see our own limitations and hence do not call our ordinary behavior erroneous merely because we do not have a robust, "superior", alternative to compare it too.
It is also possible to err in one context, and have the error be meaningful in another context. Do I need to explain that? Often, doing the "wrong" thing, looking at problems in the "wrong" way, produces changes and insights that otherwise would be ignored. The history of art and advancement of visual art since the 1800s is an example of art done "the wrong way". Physics and mathematics have long traditions of evolutions and transformations based on thinking the wrong things, or doing things the wrong way.
In nearly every human field, wrong is a matter of perspective. Because wrong, or erroneous actions open up different possibilities and outcomes. Wrong and erroneous actions can open up unexpected outcomes and this leads to new insights and developments. Errors depend critically on meaning. The history of war if full of tactical victories and strategic failures.
