Question

Computer cannot perform anything on its own..thus any error in output is not a technicological error..comment?

Answer 1

We are not sure what exactly you mean saying "Computer cannot perform anything on its own", but this is both right and wrong.

1) On the one hand, all operations going in the computer are going in its processor, memory and supplementary elements, these processes and programs are run outside of programmer's head, so the computer performs something on its own. Some external fluctuations such as electromagnetic fields or heat or computers' elements imperfections can influence the work of the computer and this will be a technological error.

2) On the other hand, imagine someone is a teacher teaching her or his students incorrect things or a teacher gives unclear instructions. Then the errors will happen because of the teacher, not the students. Speaking about computers in the context of this illustration we can say that sometimes failures occur in the code or a program and the only one whom we can blame is the programmer.

Keeping these two sings in mind we see that not any error is a technological error.
