Computability

Computability refers to whether a problem or task can be solved or performed using a well-defined procedure or algorithm. In essence, it asks if there is a step-by-step method that a computer can follow to arrive at an answer within finite time. Some problems are computable—meaning a solution exists and can be found systematically—while others are not, often due to inherent complexity or limitations of algorithms. Understanding computability helps distinguish tasks that are solvable with computers from those that are fundamentally impossible to solve algorithmically.
