As I understand, the concept 'computation' started dependent on hardware (like looms for instance).
The Hardware defines (physical cascades) what happens between input and output. I think I saw in a CS class, a mention about universal calculation where software is not limited by hardware?
It's hard to find a succint answer. What makes a universal calculator, universal?
(I'm not a CS major, so forgive my unprofessional terms and wordings) Thank you.
