Data Structure

Logical data structure uses physical data structure to implement itself.

Physical Data Structure​

  • How data is actually stored in memory(RAM, disk).
  • Deals with the real-world representation.
  • Involves memory management, allocation, data storage.
  • Impact performance and access speed.
  • Examples: Array, Linked List.

Logical Data Structure​

  • How data is conceptually organized and how operation performed on it.
  • It define relationships, hierarchy.
  • Examples: Stack, Queue.
