[LI] /dev/random & /dev/urandom - d..uh what is it?????

["Pankaj Mathur" <matsulsan@xxxxxxxxxxx>]

hi all,
just now came across two things called /dev/random & /dev/urandom. Out of 
curiosity I did cat for both of them and my screen was filled with all 
garbled stuff. What are these anyway and what possible use it has on an OS?
bye
