Joke-1 : Have you ever noticed how computers in movies differ from real ones?

Here goes:

* Word processors never display a cursor.
* You never have to use the spacebar when typing long sentences.
* All monitors display 2 inch high letters.
* High-tech computers, such as those used by NASA, the CIA, or some such governmental institution, have easy-to-understand graphical interfaces.
* Those that don't will have incredibly powerful text-based command shells that can correctly understand and execute commands typed in plain English.
* Corollary: You can gain access to any information you want by simply typing "ACCESS ALL OF THE SECRET FILES" on any keyboard.
* Likewise, you can infect a computer with a destructive virus by simply typing "UPLOAD VIRUS."
* Powerful computers beep whenever you press a key or whenever the screen changes. Some computers also slow down the output on the screen so that it doesn't go faster than you can read. The *really* advanced ones also emulate the sound of a dot-matrix printer as the characters come across the screen.
* People typing away on a computer will 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.
* If you display a file on the screen and someone deletes the file, it also
disappears from the screen.
* Whenever a character looks at a VDU, the image is so bright that it projects
itself onto his/her face.
