5. Abstraction
Abstraction is a fundamental concept in computer science. It is the process of creating a simplified model of a complex system by focusing on its essential features and ignoring the details. Abstraction allows us to understand and manage complex systems more easily.
-
Data Abstraction
Data abstraction is the process of hiding the implementation details of a data structure from the user. This allows the user to focus on the logical properties of the data structure without worrying about how it is implemented. For example, a stack can be implemented using an array or a linked list, but the user does not need to know which implementation is being used. Data abstraction is a powerful tool that can make it easier to design and implement complex systems.
-
Procedural Abstraction
Procedural abstraction is the process of hiding the implementation details of a procedure from the user. This allows the user to focus on the functionality of the procedure without worrying about how it is implemented. For example, a function to calculate the factorial of a number can be implemented using a loop or a recursive algorithm, but the user does not need to know which algorithm is being used. Procedural abstraction is a powerful tool that can make it easier to design and implement complex systems.
-
Object-Oriented Abstraction
Object-oriented abstraction is the process of bundling data and procedures together into objects. This allows us to create complex systems by combining smaller, more manageable units. Objects can be reused in different programs, which can save time and effort. Object-oriented abstraction is a powerful tool that can make it easier to design and implement complex systems.
