All computers are connected, so you can access the information on the villain's desktop computer, even if it's turned off. Powerful computers beep whenever keys are pressed or the screen changes. They also slow down the output on the screen so that it doesn't go any faster than the audience can read it. All computer panels have thousands of volts and flash pots just underneath the surface. Malfunctions are indicated by a bright flash, a puff of smoke, a shower of sparks, and an explosion that forces you backward.
People typing away on a computer always turn it off without saving the data.
A hacker can get into the most sensitive computer in the world before intermission and guess the secret password in two tries. Complex calculations and loading of huge amounts of data will be accomplished in under three seconds. In the movies, modems transmit data at two gigabytes per second. If you display a file on the screen and someone deletes the file, it also disappears from the screen. If a disk has got encrypted files, you are automatically asked for a password when you try to access it.
