What Is Linear Data Structure Give Example?

Linear data structure is a type of data structure where elements are organized in a sequential manner. In this article, we will explore what linear data structures are and provide examples to help you understand them better.

What are Linear Data Structures?

In computer science, linear data structures refer to the organization of data elements in a sequential order where each element has a unique predecessor and successor, except for the first and last elements. These structures are characterized by their simplicity and ease of implementation, making them widely used in various applications.

Linear data structures can be traversed sequentially from the beginning to the end or vice versa. The elements are stored consecutively in memory, allowing for efficient access and manipulation of the data.

Examples of Linear Data Structures

1. Arrays

An array is a basic and commonly used linear data structure that stores a fixed-size sequence of elements of the same type.

Elements in an array can be accessed using their indices, which represent their positions within the array. Arrays offer constant-time access to individual elements but have a fixed size determined at compile time.

2. Linked Lists

A linked list is another popular linear data structure that consists of nodes where each node contains a value and a reference (or link) to the next node in the sequence.

Unlike arrays, linked lists can dynamically grow or shrink as needed. They allow efficient insertion and deletion operations but have slower access times compared to arrays since traversing requires iterating through each node.

3. Stacks

A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle.

Elements can only be inserted or removed from one end called the top of the stack. Stacks are commonly used in programming languages for function call management, expression evaluation, and undo operations.

4. Queues

A queue is a linear data structure that follows the First-In-First-Out (FIFO) principle.

Elements are inserted at the rear and removed from the front of the queue. Queues are widely used in scheduling, resource allocation, and breadth-first search algorithms.


Linear data structures provide a simple and efficient way to organize and manipulate data in a sequential manner. Arrays, linked lists, stacks, and queues are some common examples of linear data structures that find applications in various domains. Understanding these structures is essential for effective problem-solving and algorithm design.
