# Introduction to Data Structure

## What is the Data Structure?

• The data structure is one of the best ways that organize the data in memory which help to perform some operation on the data efficiently/quickly. Like – Searching, Inserting, Retrieving, Traversing, Sorting, Merging, etc.
• The Logical and Mathematical model of a particular organization of data is called a data structure.
• The data structure is the process of organizing, managing, and arranging, data in memory which help to perform the operation quickly/efficiently.

Data Structure: the data structure is a process of arranging the data which are used efficiently in main memory.

Algorithm: The algorithm is the sequence of steps that are performed on the data and that solved given problems.

## Operation of Data Structure

• Insertion: the insertion means inserting a new element in the data structure.
• Deletion: – the deletion means deleting the element from the data structure.
• Searching: – searching means searching a particular element in the data structure.
• Traversing: – traversing means showing/displaying all elements whose presence is in the data structure.
• Sorting: – sorting means all elements set in the ascending or decerning order.
• Merging: – mearing means combining two or more similar elements in the single one.

## Need of Data Structure

• Data Structures are an important way of organizing data in a computer.
• It has a different way of storing and organizing data so that it can be used efficiently.
• It helps us to understand the relationship between one data element with another.
• it helps to store data in logical order.
• it stores data that may grow and shrink dynamically over time and allows efficient access.
