### Are lambda calculus and turing machines computable models that answers the question on what does computable mean?

Lambda calculus and Turing machines are indeed foundational models in theoretical computer science that address the fundamental question of what it means for a function or a problem to be computable. Both models were developed independently in the 1930s—lambda calculus by Alonzo Church and Turing machines by Alan Turing—and they have since been shown to

The question of whether all languages are Turing recognizable is a fundamental one in the field of computational complexity theory and the theory of computation. To answer this question comprehensively, it is crucial to consider the definitions and properties of Turing machines, the classes of languages they recognize, and the distinctions between different types of

### Can a computation of deterministic turing machine be shown on a tree in contrast to computation of a nondeterministic turing machine?

A Turing machine (TM) is a theoretical model of computation that defines an abstract machine capable of simulating any algorithm. Turing machines can be classified into two primary types: deterministic Turing machines (DTMs) and nondeterministic Turing machines (NTMs). Understanding the computational processes of these machines is fundamental to the study of computational complexity theory. A
