85 C.E. I think that is when it was written, but I’m not 100% sure.
Imformation goes into a computer through wires and comes out through data/gigabites. Or when you print it.
Let's say for example you have a toddler, or a pet. Let's say a cat. If the ctrl+alt+delete wasn't there. It would go straight to entering the password. Now let's say your child or pet likes to press the keys for a while. If they manage to press enter and enter the incorrect password. Eventually it will lock up your computer.
