In liknked list insertion and deletion can be done anywhere in the structure, since the previous and next elements in the structures are linked to each other.

Whereas in arrays, there is no link between the elements in the structure, therefore insertion and deletion cannot be performed anywhere in the structure. It can only be performed at the end of the structure.

1. The allocation of array elements in memory is contiguous. Each element in a Linked list can be placed anywhere in the memory.

2. Once defined, array size cannot be modified. In a linked list size can be modified dynamically.

3. Array is random access structure. Meaning, we can directly access the nth element by its index value. Linked list is sequential access data structure. In order to access nth element, we need to traverse all the nodes from starting till nth element.
