Applications of Linked List

Linked Lists are fundamental data structures with a wide range of applications in computer science and real-world software systems.

Key Applications

• Image Viewer Navigation: Access previous and next images efficiently using linked nodes.
• Browser History Navigation: Back and forward browsing is managed using doubly linked lists.
• Music Players: Organize songs in playlists allowing next and previous track navigation.
• Task Scheduling: Operating systems use linked lists to manage process scheduling.
• Polynomial Manipulation: Store polynomial terms as nodes for efficient mathematical operations.
• Undo/Redo Functionality: Applications implement undo/redo stacks using linked lists.
• Graph Adjacency Lists: Represent graphs efficiently with adjacency lists using linked lists.
• File Systems: Directories and files organized as linked structures.
• Memory Management: Linked lists manage free/used memory blocks dynamically.

Real-World Examples

• Microsoft Word / Google Docs undo and redo features
• Web browser navigation history
• Media player playlist management
• Operating system task management and process scheduling
• Social networks like Facebook representing friend connections

These applications leverage the flexibility and dynamic nature of linked lists to efficiently manage and organize data.
