Is it a linear system? Casual system? Please explain why and how.
No it's not a homework question.This sounds like homework. Nevertheless...
Neglecting the fact that computers are enormously complex and flexible systems--will computers do preempting or in the absence of user input?
As for linearity--I think... think... FATAL EXCEPTION #2477: DOES NOT COMPUTE
EDIT: Okay, a philosophical discussion item: what do you consider as computer input...?
Well, you could set an alarm to trigger an action, but that's probably semantics. I think the bigger issue is that you can't apply these simple classifications to a computer on its own, irrespective of the programming.how does causality not apply? A PC can create outputs based on inputs from the future?
