👉 Non-computation is a concept in computer science that refers to an action or operation performed on data that has not been executed. In other words, it is an action or operation that does not occur because no data was produced as a result of the execution of that action or operation. For example, if you were to perform an arithmetic operation on two numbers and get a result, but then you did not execute any code (such as writing to a file), this would be considered non-computation.
