keyboard input

["Elias Kopsiaftis" <yemista@xxxxxxxxx>]

How does linux handle keyboard input? I dont mean how the interrupt works, I mean where does it store the keystrokes?
Is there some global buffer that it just puts them in until someone reads from it? I did some I/O programming in school,
and thats how we did it, but we used the UART and never touched the keyboard interrupt.
