Data Structures are fundamental concept of computer science, way to organize, manage, and store data efficiently so that it can be accessed and modified. They are critical for designing efficient algorithms and help manage data effectively. 

Advantages:-

           # Efficiency: Proper data structures can greatly enhance the speed and performance of computer programs, especially in handling large volumes of                           data.

           # Data Management: They allow for easier management of data in complex computing tasks and algorithms..

Dis-advantages:-

           # Complexity: Implementing and understanding certain data structures can be complex, require deep knowledge of algorithms and memory management.

           # Performance Trade-offs: While one data structures might offer excellent performance for certain operations (like insertion and deletion in                         linked lists). it might perform poorly for others (like random access in linked lists).
