Data Structures Notes: Anything that can store data is called Data Structure. There are two types of data structures. One is a primitive data structure, and another is an abstract data structure. Data structures help us to perform various operations on data. Data structures store the ordered data so that different kinds of operations can be performed easily. In this article, you will get complete details about the data structure reference books, study materials, and Lecture Notes.

## Introduction to Data Structures Notes

The data structure is the process in which ordered data is collected and organised in such a way that we can perform various kinds of operations with this data efficiently. For example, if we have some data, which has the player’s name ‘Messi’ and age ’31’, Messi is the string data type, and 31 is the integer data type. The data structure is the process of organising the knowledge of data in memory. The data structure is done in a way that reduces complexity and increases efficiency. This article will help you to get more information on the data structure.

Students interested in pursuing a course in Data Structure can avail the study materials and study notes from this article. Study materials of data structure will help in your preparation. You can download the study material and notes from here and read it offline as well. Study materials for Data Structure are listed below:
