How is "abstraction" defined in computer science?

In computer science, "abstraction" refers to the process of simplifying complex systems by reducing unnecessary details. This allows programmers and designers to focus on higher-level functionalities without getting bogged down by the complexities of implementation. By using abstraction, developers can represent complex ideas or processes in a more understandable way, distilling them down to the essential characteristics that are relevant for a specific task or problem.

For example, when using a programming language, abstraction allows developers to use functions, classes, or libraries without needing to know the intricate details of how they work internally. This enables reuse of code, enhances maintainability, and allows for easier problem-solving.

The other choices present concepts that, while important in their own rights, do not align with the definition of abstraction in computer science. Techniques for binary data storage, methods for creating user interfaces, and processes for memory allocation do not inherently involve the simplification of complexities or the reduction of details, which are the core aspects of abstraction.
