Adatabsztrakciók refer to the process of hiding the complex implementation details of data structures and providing a simpler, more abstract interface to interact with them. This concept is fundamental in computer science and programming, allowing developers to focus on what a data structure does rather than how it does it. By abstracting away the underlying mechanisms, users can manipulate data without needing to understand the intricate algorithms or memory management involved.

Key to data abstraction is the separation of the interface from the implementation. The interface defines the operations that can be performed on the data, such as adding an element, removing an element, or retrieving a specific value. The implementation, on the other hand, details how these operations are actually carried out within the chosen data structure. This separation promotes modularity and allows for changes in the implementation without affecting the code that uses the abstract data type, as long as the interface remains consistent.

Common examples of abstract data types include lists, stacks, queues, trees, and graphs. While a programmer might use a "list" abstract data type, the underlying implementation could be a linked list, an array, or some other structure. The choice of implementation can affect performance, but the user of the list abstract data type interacts with it in the same way regardless of its internal workings. This principle is crucial for building robust, maintainable, and scalable software systems.
