Introduction

Nowadays, in the technology influenced world, Data and its information is a more essential part, and various implementations are made to store in different ways. A data structure is a particular way of organizing data in a computer so that it can be used effectively.

For example, we can store items with same data type can be stored in array data structure.

In the above example, the characters are stored in the array with the contiguous memory location.

Data can be stored in many different ways such as logical or mathematical for a particular organization of data is termed as data structure. The specific data model depends on two factors:

• Firstly, it must be loaded in structure to reflect the actual relationships of data in the real world object.
• Secondly, they should be stored in a simple enough so that anyone can process the data efficiently when necessary.

• Linear Data Structure
• Non-linear Data Structure

• The first step is to provide the linear relationships among all the elements represented using linear memory location. These linear structures are nothing but arrays.
• The second step is to provide a linear relationship between all the elements through pointers or links. These linear structures are termed as linked lists.
