Do computers make mistakes?

Question

Or is everything human error? Either programing or user interaction?

Answer 1

I'm a computer scientist, so I deal with computers everyday. No, computers don't make mistakes. They _can't_ make mistakes. Why is this? A mistake is when someone does something they didn't intend to do. A computer can't _intend_ anything, it's just a physical commodity that manipulates an input by a predetermined algorithm to achieve an output - to put it bluntly it has no consciousness, no free will, no intelligence. A computer is a tool - it can only do what it's been programmed to do. Any intelligence or complexity "contained" in the computer is contingent upon the programmer or user who put it there in the first place.

So any "mistake" involving a computer is always on the part of the programmer or user, because the outcome was not what the _programmer_ or _user_ intended. The computer couldn't care less either way. Even if the computer had a hardware problem and gave the wrong answer, it wouldn't be technically correct to call what the computer had done a "mistake" - "error" would be a more appropriate term.

Answer 2

No. Computers do not make mistakes. In layman's terms, computers do exactly what they are instructed to do, repeatedly. If they don't "understand" how to do something, they return an "error". These "errors" are not mistakes, but messages returned to the user or programmer signifying that the computer doesn't understand the instruction, or something happened that the comptuer wasn't programmed to handle.

The next time your bank tells you "it was a computer error," you can bet your problem was caused by a person, and may have even been intentional.

Computers don't make mistakes. People make mistakes -- data entry, software development, database queries, etc.

Bryan that is such a broad question, can you be more specific? General as your question is, let me answer it as follows: Mistakes made by computers are generally classifed into three categories: 1) Mistakes made by incorrect data input. 2) Mistakes in the code for an unexpected event. 3) Errors resulting from harware devices.

Answer 4

No, computers do as they are told and only that. The errors are glitches in the program. If the MS calculator did not carry the 1, most people will think that the computer screwed up. No. The programmer forgot to include that step in the equation.

Answer 5

computer is straight forward, garbage in garbage out (GIGO), when u have bad data then u'll have bad result

most of da mistakes are coming from human error, logical error or rubbish data. but sometimes there'll be exception error that cannot handle by computer as well

Answer 6

It is seldom the processors fault, but they can make random errors. A discharge can flip a switch from on to off. It would be akin to throwing a coin a million times and instead of a head or tail you would have one land on its edge.

Answer 7

No, because we're the ones writing the programs all they do is process what we tell them so basically we make the mistakes but blame it on the pc to not feel stupid.

Answer 8

Yes there call: computer errors in which a computer can't compute

Answer 9

Of course.

Answer 10

not it is the person who is using it that makes the mistakes
