A data structure is a Specific way to store and organize data in a computer's memory so that these data can be used efficiently later. Data may be arranged in many different ways, such as the logical or mathematical model for a particular organization of data is termed as a data structure. The variety of a specific data model depends on the two factors -

• Firstly, it must be loaded enough in structure to reflect the actual relationships of the data with the real-world object.
• Secondly, the formation should be simple enough so that anyone can efficiently process the data each time it is necessary

CATEGORIES: 

The data structure can be subdivided into major types:

• Linear Data Structure
• Non-linear Data Structure

The common examples of the linear data structure are:

• Arrays
• Queues
• Stacks
• Linked lists

Examples of Non-Linear Data Structures are listed below:

• Graphs
• the family of trees and
