Pointer to next node:- Each node holds the address of the next node. Each node in a linked list is connected to next node using pointer. Dynamic Size:- Memory allocation to linked list elements is done dynamically. So, we can add more and more elements in a linked list easily as compared to arrays.
There is an upper limit on the number of elements in array as the size of array is fixed. Ease of Insertion and Deletion:- Insertion and deletion of an element in a linked list is very easy as compared to arrays and can be done in O 1.
In array insertion of an element needs room for that element and shifting of elements. Extra memory space for pointers:- As each node in a linked list consists of pointers which hold the address of next node, so an extra memory space for a pointer is required with each element of linked list.
Random access not allowed:- Random access of an element in a linked list is not allowed. By practicing how to manipulate linked lists, you can prepare yourself to learn more advanced data structures like graphs and trees.
