Abstraction in programming is the process of generalizing concrete details, such as attributes, away from the study of objects and systems to focus attention on details of greater importance). It is one of the most important and essential features of object-oriented programming. Abstraction is used to hide background details or any unnecessary implementation about the data so that users only see the required information. Its main goal is to handle complexity by hiding unnecessary details from the user. Abstraction is a general concept which you can find in the real world as well as in OOP languages.

Here are some key points about abstraction in programming:

• Abstraction is one of the key concepts of object-oriented programming (OOP) languages.
• Abstraction is used to handle complexity by hiding unnecessary details from the user.
• Abstraction is a process by which we design our software entities according to how much detail they internally (privately) expose to other entities.
• Abstraction is a fundamental concept in computer science and software engineering, especially within the object-oriented programming paradigm).
• Abstraction can be implemented with classes. Classes have private and public identifiers to limit the scope of any variable or a function.
• Abstraction can be used to separate usage from working representations of data within programs).
• Abstraction is a general concept which you can find in the real world as well as in OOP languages.

In summary, abstraction is a process of generalizing concrete details to focus on details of greater importance. It is a fundamental concept in computer science and software engineering, especially within the object-oriented programming paradigm. Abstraction is used to handle complexity by hiding unnecessary details from the user.
