Random stuff in computers.

[Deleted]

hi

this may not be completely wow related, but it's definitely something about computers. I've always been wondering how a computer can make randoms stuff happend, like /roll and all that. I have been searching for a while on google, but i can't find something that explains it so i understand it.

Anyone mind helping me understand it?

thanks

REAL Random stuff cant be done with a computer...

Randomness in computers is based on stuff that 'looks' random, for example time (BIOS keeps time with millisecond precision) or "how many times user has clicked mouse during last 5 minutes". Neither of those are really random, but when enough of pseudo-random variables like that are multiplied together, odds at hitting exact same number many times will be smaller than winning lottery.
