<ul><li>Data structures are the building blocks of efficient software in programming.</li><li>1. Array: Fast access via index, fixed-size (in most languages), used for ordered collections.</li><li>2. Linked List: Dynamic size, inefficient random access, used for frequent insertions/deletions.</li><li>3. Stack: LIFO structure, useful for backtracking and managing function calls.</li><li>4. Queue: FIFO structure, used in scheduling and task management.</li><li>5. Hash Table: Optimized for quick lookups, used for dictionaries and caching.</li><li>6. Binary Tree: Hierarchical structure, used for organizing data and search algorithms.</li></ul>
