# Applications, Advantages and Disadvantages of Binary Tree

A binary tree is a tree that has at most two children for any of its nodes. There are several types of binary trees. To learn more about them please refer to the article on “**Types of binary tree**“

__Application of Binary Trees:__

- Huffman coding tree is an application of binary trees that are used in data compression algorithms.
- In compilers, Expression Trees are used which are applications of binary trees.
- Priority Queue is another application of binary tree that is used to search maximum or minimum in O(log N) time complexity.
- Represent hierarchical data.
- used in editing software like Microsoft Excel and spreadsheets.
- useful for indexing segmented at the database is useful in storing cache in the system,
- syntax trees are used for most famous compilers for programming like GCC, and AOCL to perform arithmetic operations.
- for implementing priority queues.
- used to find elements in less time (binary search tree)
- used to enable fast memory allocation in computers.
- to perform encoding and decoding operations.

__Real-time applications of Binary Trees:__

- DOM in HTML.
- File explorer.
- Used as the basic data structure in Microsoft Excel and spreadsheets.
- Editor tool: Microsoft Excel and spreadsheets.
- Evaluate an expression
- Routing Algorithms

__Advantages of Binary Tree:__

- The searching operation in a binary tree is very fast.
- The representation of a binary tree is simple and easy to understand.
- Traversing from a parent node to its child node and vice-versa is efficiently done.
- simple to implement
- easy to understand.
- a hierarchical structure.
- reflect structural relationships that are present in the data set
- easy to insert data than in another data store.
- easy to store data in memory management.
- user can many nodes
- executions are fast.
- store an arbitrary number of data values.

__Disadvantages of Binary Tree:__

- In binary tree traversals, there are many pointers that are null and hence useless.
- The access operation in a Binary Search Tree (BST) is slower than in an array.
- A basic option is dependent on the height of the tree.
- Deletion node not easy.
- A basic option is based on the height of tree.
