Certainly! **Data structures** are fundamental building blocks in computer programming. They define how data is organized, stored, and manipulated within a program. Here are some key points: 1. **Definition**: A data structure is a way of arranging data on a computer so that it can be accessed and updated efficiently. It's not only about organizing data but also processing, retrieving, and storing it. 2. **Classification**: - **Linear Data Structures**: Elements are arranged sequentially (e.g., arrays, linked lists, stacks, queues). - **Static Data Structures**: Fixed memory size (e.g., arrays). - **Dynamic Data Structures**: Size can change during runtime (e.g., queues, stacks). - **Non-Linear Data Structures**: Elements aren't placed linearly (e.g., trees, graphs). 3. **Importance**: Understanding data structures is crucial for developing efficient algorithms and solving real-world problems.
