Ans to the question no-02

  Data Structure is the combination of data objects which gives a way of collecting and handling data in the computer so that it can be used. Their various types are arrays, Linked List, Stack, Queue, etc. Data Structures are used extensively in nearly every aspect of Computer Science for simple as well as complex calculations. They are practiced in all such areas such as AI, Graphics, Operating System, etc. 

Data Structures are a crucial part of several computer algorithms as they allow programmers to do data management efficiently. A wise selection of data structures can improve the performance of a computer program or algorithm in a more useful way.
