Abstraction is categorized as Data Abstraction and Procedural Abstraction. In data abstraction, the way the data are stored e.g. the structure or arrangement of data is hidden.
Procedural abstraction on the other hand, hides the details on how the function/procedure/method works. You must only know the inputs and the expected outputs, much like a black-box. The two ideas combined serve as one of the important concept in OOP called Encapsulation.
As an example, when you create a class for StudentGrades, the variables and their structure for representing grades is hidden by using the private keyword, you only provide methods to access and manipulate this data.
