‘Turing machine’ serves as

A Turing machine is a theoretical computing machine proposed by Alan Turing in 1936 that serves as an ideal model for mathematical calculation. It is a fundamental concept in computer science that defines the limits of what can be computed using an abstract mathematical model of a device that manipulates symbols on a strip of tape. While modern computing involves advanced automation and machines that can 'think' through feedback systems [3], the Turing machine remains the foundational blueprint for the logical structure of all digital computers. It is not related to physical instruments for identifying explosives [1], forest fire prediction models which utilize machine learning and neural networks [4], or instruments for measuring physical constants. Instead, it provides the theoretical framework for understanding algorithms and computational complexity.
