The Abstract Model
Captions available
The idea
An abstract model is a computational model for thinking rather than running — a tool for devising algorithms, analyzing efficiency, and proving what algorithms can and cannot do.
In practice
The Random Access Machine, the Turing machine, and the Lambda calculus each carry proofs, not products.
Where people slip
Ignoring hardware detail is the feature.
