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 table of contents
