Root Node
Root Node
The topmost node in a tree's hierarchical structure; the only node with no parent.
Binary Tree
Binary Tree
A tree where each node has at most two children, typically referred to as the left child and the right child.

Study Notes
Tree Data Structure
- The root node of a tree is the top-most node in the hierarchy.
Characteristics of Trees
- A key characteristic of a tree data structure is that it is a non-linear data structure.
Binary Trees
- In a binary tree, each parent node can have a maximum of two children.
- A binary tree is a type of tree that limits the number of children for each parent to at most two.
Tree Traversal
- Recursion is commonly used in tree traversal to traverse the tree.
- The purpose of recursion in tree traversal is to traverse the tree.
Trees vs. Linear Data Structures
- Trees are different from linear data structures because they are non-linear.
