Is algorithmically computable problem a problem computable by a Turing Machine accordingly to the Church-Turing Thesis?
The Church-Turing Thesis is a foundational principle in the theory of computation and computational complexity. It posits that any function which can be computed by an algorithm can also be computed by a Turing machine. This thesis is not a formal theorem that can be proven; rather, it is a hypothesis about the nature of

Can a turing machine decide and recognise a language and also compute a function?
A Turing machine (TM) is a theoretical computational model that plays a central role in the theory of computation and forms the foundation for understanding the limits of what can be computed. Named after the British mathematician and logician Alan Turing, the Turing machine is an abstract device that manipulates symbols on a strip of

Can a tape be limited to the size of the input (which is equivalent to the head of the turing machine being limited to move beyond the input of the TM tape)?
The question of whether a tape can be limited to the size of the input, which is equivalent to the head of a Turing machine being restricted from moving beyond the input on the tape, delves into the realm of computational models and their constraints. Specifically, this question touches upon the concepts of Linear Bounded
Are all languages Turing recognizable?
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.

What are some examples of operations that can be performed on a Turing machine?
A Turing machine is a theoretical computational model that consists of an infinite tape divided into cells, a read-write head, and a control unit. The control unit is responsible for determining the behavior of the machine, which includes performing various operations on the tape. These operations are essential for carrying out computations and solving problems.
