Linked List Vs. Arrays

Both Linked list and Arrays are linear data structure used to store data. The major difference between array and linked list lies in the structure of the array and linked list and how data is stored in both of them.

Basis of Difference	Linked List	Arrays
Basic Definition	Linked list is a collection of similar type of data connected with links/pointers.	Array is a collection of elements having same data type.
Memory structure	Each node of a linked list is not stored in contiguous manner in memory.	Array elements are stored in contiguous manner in memory.
Size	The size of the linked list is of variable length. It is not fixed.	The size of array is fixed and specified at the time of declaration.
Memory Required	It requires more memory because of the pointer part of the node.	It requires less memory as compared to linked list.
Accessing of Elements	The elements of the linked list can be accessed sequentially. To access any element of the linked list, traversing of list is required.	The elements of the array can be accessed randomly or directly with index position
Insertion and Deletion Operation	In linked list, the insertion and deletion takes less time because it does not require shifting of elements, only pointers are manipulated for insertion and deletion operation.	In arrays, the insertion and deletion takes more time as shifting of elements is required.
