following instructions and computers

For the past few weeks we have done activities that involved us to figure out or create instructions.i have learned that when human get instructions and they don't  understand they will figure it out. If a computer gets instructions and it doesn't understand it will crash and shut down.if there is an error a human will figure it out and fix the error but if the computer see an error it doesn't know what to do or how to fix it cause it was not programmed to fix error that may occur.
