Linked list, single linked list, double linked list, queue, set, sequential storage structure, chain storage structure, which is the data structure and which is the storage structure?

  c++, question

How do they distinguish who is the storage structure and who is the data structure?
Thank you

Data structure is an abstract data management method. Linked list, queue and set are all data structures. The corresponding storage method in actual physical memory is called storage structure. For example, the implementation of linked list is usually reflected as a chained storage structure in memory, while the implementation of queue may be reflected as a sequential storage structure in memory.
