In what situations would a computer be more appropriate than a person?

because if you need an answer and a human doesent know the answer the comper may have it.

Answer

If a task has to be performed the same way repeatedly a computer is better than a human, like the manufacture of car parts or electronic circuit boards. There are dangerous environments that a human cannot work in where a computer will work perfectly well. Long distance space missions lasting several years for instance are best done, presently, by computer.
