### Recognizable vs Decidable Mathematics Stack Exchange

If the machine keeps computing forever, we consider that the machine has rejected the string but it does so in an infinite number of steps. Thus, if the machine accepts a string, it must do so in a finite number of steps! A Language of a Turing Machine is simply the set of all strings that are accepted by the Turing Machine.
