Introduction to Data Structure

Mr. Pushpendra Kumar Assistant Professor (CSE) IIMT College of Engineering, Greater Noida

Introduction • Data Structure is a way of collecting and organizing data in such a way that we can perform operations on these data in an effective way. • The logical and mathematical model of a particular organization of data is called data structure.

• Data Structures are widely used in almost every aspect of Computer Science i.e. Operating System, Compiler Design, Artificial intelligence, Graphics and many more. • Data Structures are the main part of many computer science algorithms as they enable the programmers to handle the data in an efficient way. • It plays a vital role in enhancing the performance of a software or a program as the main function of the software is to store and retrieve the user's data as fast as possible.

Data Structure Classification

Data Structure Advantages • Efficient Memory use: With efficient use of data structure memory usage can be optimized, for e.g we can use linked list vs arrays when we are not sure about the size of data.

• Reusability: Data structures can be reused, i.e. once we have implemented a particular data structure, we can use it at any other place.

• Abstraction: Data structure serves as the basis of abstract data types, the data structure defines the physical form of ADT(Abstract Data Type). ADT is theoretical and Data structure gives physical form to them.
