An array and a linked list are both linear data structures, but they have several key differences:

1. Memory Allocation: In an array, memory is allocated during compile time, making it static. On the other hand, in a linked list, memory is allocated during runtime, making it dynamic.

2. Memory Usage: An array uses less memory because it does not require any extra storage for pointers as in the case of a linked list. However, in an array, the size is fixed and a large portion of memory may be wasted if the array is not fully utilized.

3. Insertion and Deletion: In a linked list, insertion and deletion of nodes are easier as it requires only the change of the address present in the next pointer of a node. But in an array, shifting of elements is required during the insertion and deletion of an element.

4. Random Access: Arrays allow random access of elements as it has direct access to any element in the array. This is not possible in linked lists.

5. Performance: Accessing an element in an array is faster, while elements in a linked list have to be accessed sequentially from the first node.

6. Flexibility: A linked list is more flexible as the memory can be allocated as and when needed. This is not the case with arrays.

In summary, the choice between an array and a linked list depends on the requirements and constraints of the problem you are trying to solve.
