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 DifferenceLinked ListArrays
Basic DefinitionLinked list is a collection of similar type of data connected with links/pointers.Array is a collection of elements having same data type.
Memory structureEach node of a linked list is not stored in contiguous manner in memory.Array elements are stored in contiguous manner in memory.
SizeThe 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 RequiredIt requires more memory because of the pointer part of the node.It requires less memory as compared to linked list.
Accessing of ElementsThe 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 OperationIn 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.
