👉 The term "uncomputable" is often used in mathematical and computational science to describe a function or algorithm that cannot be computed by any computer, Turing machine, or other computing device. This can happen because of limitations in hardware performance, the nature of computation itself (such as the difficulty of finding an exact solution), or the complexity of the problem at hand. In mathematics, uncomputable functions are often used to describe non-deterministic and uncertain situations where a function cannot be computed with certainty
