Computer comes with exception

Computers are sometimes exceptional.their act make us wonderful.
for example doing some work with computer is your daily job and always you do a routine task.It always seems normal and after many many times it sounds a good way to do this task.but very chancy one time that you are doing this routine job,something go wrong!
yes you try to fire up your intelligence mind and solve this problem.may be it get a long time to solve this problem to you,and may be it will be solved with a lil trick.absolutely it depends on your experience and may be your fortune.

But there is many many occasion that not computer logic exceptional.because many events are based on concepts.concepts always forced by us to computers.some concepts are documented and some not.some are intentional and some not.
I believe the exceptional that i said at beginning of this post is a kind of inadvertent undocumented concepts.They forced to the computer by writing the codes from programmer.The computer never disobeys from programmer in normal mode,because it's logic is based on the obey.
So we must try to be careful about any concept that we are learning to computer!
yes,this is very important.If we want,we can teach computer to disobey us.we can force computers to disobey us,and this may be the last obey of computer from us.They can learn from us to be our malicious foe.
So,be careful about what concept you are learning to your computer...
