Three Kinds of Models
Captions available
The idea
Computational models come in three working kinds: hardware models built for machines, programming models built for humans writing code, and abstract models built for reasoning about algorithms.
In practice
A curriculum meets all three — circuits in one course, coding in another, proofs in a third.
Where people slip
Each kind answers to a different customer.
