What Is Advantage of Linked List in Data Structure?


Larry Thompson

When it comes to data structures, the linked list is a powerful and versatile choice. It offers several advantages over other data structures like arrays and can be used in a variety of applications. In this article, we will explore the advantages of linked lists and why they are so commonly used.

Dynamic Size

Unlike arrays, linked lists have a dynamic size, which means they can grow or shrink as needed. This flexibility makes linked lists ideal for situations where the size of the data may change over time. For example, in a program that manages a list of tasks, new tasks can be easily added or removed from the linked list without worrying about resizing or shifting elements.

Efficient Insertions and Deletions

One of the key advantages of linked lists is their efficiency in performing insertions and deletions. Unlike arrays, where inserting or deleting an element requires shifting all subsequent elements, linked lists only require updating a few pointers. This makes operations like inserting an element at the beginning or middle of a list much faster compared to arrays.


  • Insertion: Suppose we have a linked list with nodes A -> B -> C. To insert a new node D between B and C, we simply update the pointers: A -> B -> D -> C.
  • Deletion: Similarly, if we want to delete node B from the above example, we update the pointers: A -> D -> C.

Memory Efficiency

In terms of memory usage, linked lists are more efficient than arrays for certain scenarios. While arrays require contiguous memory allocation for all elements, linked lists can utilize scattered memory locations as each node contains a reference to the next node. This means that linked lists can efficiently use available memory without worrying about fragmentation.

Easy Implementation

Implementing a linked list is relatively straightforward. Each node in the list contains a value and a pointer to the next node.

This simplicity makes linked lists a popular choice for beginners learning about data structures. Additionally, various types of linked lists like singly linked lists, doubly linked lists, and circular linked lists can be implemented based on specific requirements.


The advantages offered by linked lists make them an essential tool in data structure design. Their dynamic size, efficient insertions and deletions, memory efficiency, and ease of implementation make them suitable for a wide range of applications. Understanding the advantages of linked lists will help you make informed decisions when choosing the appropriate data structure for your programming needs.
