Question

Which one of the following is a physical data structure ?

• A. Array
• B. Linked lists
• C. Stacks
• D. Tables

Answer 1

Linked List, Stack, and Tables are Abstract Data Type (ADT). They can can be accessed through some well-defined operations such as PUSH and POP in the case of Stack.

Whereas an array is a primitive data type that we can access and modified with low-level code such as memory offset or index. Hence array is a physical data structure.
