any Computer Tree is used to create and represent the structure of data in the way a house is designed to be built and a structure is prepared of how and where to set all the things, in the same way a tree is used to prepare the structure of data in any computer.
Today in this article we What is E-Tree in Data Structure and what are its uses Will understand in detail about the data structure of a computer, if many of you do not know what is E-Tree, then definitely read this post till the end so that you can get complete information about it.

what is tree in data structure What Is Tree In Data Structure
Tree in data structure is a hierarchical data structure which is a collection of nodes connected by edges. All the nodes in a tree represent some object or data and the data value of each node may or may not have child nodes.
Glossary of Tree in Data Structure Terminologies Of Tree In Data Structure
The following terms are associated with the tree in the data structure, which are as follows: –
1. Root – This is the top most point of the tree which is called root.
2. Node – A node is a unit of the entire data structure, meaning all the elements present in the tree are called nodes.
4. Degree of Node – The degree of a node is called that which the top most node is connected to any other node means the total number of branches of that node.
5. EDGE – The connecting link between two nodes in a tree data structure is called an EDGE.
6. Child Node – In a tree data structure a node that has descendants is called a child node. Simply put, a node that is connected to and dependent on another node is known as its parent. So all nodes in a tree except the root are child nodes.
7. Siblings In a tree data structure, the nodes related to the parent are called siblings.
8. Leaf Node – In a tree data structure, the node which does not have any child is called a leaf node.
9. Sub Tree – Sub tree in tree data structure means that it consists of a node and all its descendants. Each child node forms a subtree on its parent node.
Types of Tree in Data Structure Types Of Tree In Data Structure
There are many types of trees in the data structure which are as follows:-
1. Binary Tree –
Binary tree is a tree data structure in which each node has maximum two children referred as left child and right child as the name suggests binary means two so each node can have 0, 1 or 2 nodes.
A binary tree is a type of non-linear data structure where data is stored in nodes. Binary trees are used to represent hierarchical relationships, for example the structure of a file system or the organization chart of a company. Binary trees are widely used in computer science. This type of tree data structure allows for each parent to have at most two children.
2. Binary Search Tree –
Binary search tree is non-linear and a node is connected to many nodes. It is similar to a type of binary tree in which the value of each node is greater than or equal to its left child and less than or equal to its right child.
Binary tree is a data structure that allows efficient search and deletion of elements. Binary search tree works as an extension of binary tree with many optional restrictions. This is one of the properties of tree in data structure that makes binary search tree perfect for search operation. This is because it helps you to determine exactly whether the value is present on the right or left sub-tree. Hence binary search tree is also known as search tree. Known and it is perfect for search operation as it helps to know where to go.
3. AVL Tree –
AVL tree is a self-balancing binary search tree data structure. It is a type and variant of binary tree. It has properties of both binary search tree and binary tree. It maintains the property of height balancing by requiring that the difference in height between the left and right subtrees of each node be at most 1, so it is measured in terms of balance factor.
The AVL tree is different from other types of tree data structures because it was the first tree that was dynamically balanced. This results in O(log n) height which provides efficient search and deletion operations. Therefore AVL trees are widely used in computer science for various applications including dictionary data structures for fast lookup and storage.
4. B-Tree
B-tree is a self-balancing tree data structure which is a generalized form of binary search tree. Each node of this tree can have more than one key and more than two child nodes. It is used to store large amount of data in file system or database.
B-trees are known for their high performance, scalability, and ability to handle large amounts of data, making them a popular choice for many data storage applications. B-trees are also widely used in computer science.
Application of Tree in Data Structure Application Of Tree In Data Structure
Trees are widely used in computer science and data structures as it provides for organizing, storing and retrieving data. Let us now understand some of the common applications of trees in data structures:-
- Binary tree can be used to find an element in a set of elements.
- Tree is used in data structure to organize and store the files and directories present in the file system in a sequential manner.
- Trees are used to represent the structure of a graph algorithm.
- B-Tree and T-Tree are used by most of the popular databases to store their data.
- Trees are used in data compression algorithms for example Huffman coding to efficiently encode data.
So these were some common applications of tree in data structure apart from this there are many areas where tree can be used to solve problems in data structure more efficiently.
Frequently asked questions on Tree in Data Structure FAQs On Tree In Data Structure
Q1. What are the uses of tree in data structure?
Answer – There are various uses of tree in data structure like storing data, organizing data, retrieving data and efficient way. Tree is used in data structure in addition to this it is mainly used for file system, database, graph algorithm, decision making process etc.
Q2. What is Self-Balancing Tree?
Answer – A self-balancing tree is a type of data structure that automatically balances its height by adjusting the position of nodes and ensures that the height of the tree is balanced even after insertions and deletions.
Q3. What is the difference between tree and binary tree?
Answer – A tree is a general data structure in which each node can have many children, on the other hand, a binary tree is a special type of tree where each node can have at most two children.
