What do data structures serve as a basis for
Data structures serve as the basis for abstract data types
What do data structures help design
Efficient data structures are key to designing efficient algorithms.
Where do data structures retrieve information from
Data structures can be used to organize the storage and retrieval of information stored in both main memory and secondary memory
