In reality, this doesn't happen. This is done in movies to make it look dramatic and exciting. Real computer hacking involves staring at a computer screen for hours of a time, searching a lot on Google, muttering "hmmm" and various expletives to oneself now and then, and stroking one's hacker-beard while occasionally tapping on a few keys.
