Trees Data Structure | Easy Explanation with Examples | 1st Year Computer Science
Chapter 04: Computational Structures – Lecture 04: Trees
Welcome to another class with Sir Muhammad Iqbal on CS with Sir Iqbal!

In this lecture, we’ll explore one of the most important and fascinating data structures — the Tree
Trees help us organize information in a hierarchical way, just like a family tree or a computer folder system.

You’ll learn:
✅ What is a Tree?
✅ Structure of Trees (Root, Nodes, and Edges)
✅ Properties of Trees (Height, Balanced Tree, etc.)
✅ Real-life Examples (Family Tree)
✅ Applications of Trees in Computer Science

By the end of this lecture, you’ll clearly understand how trees work and why they’re essential for representing hierarchical data such as file systems, organizational charts, and decision-making models.

Chapter Overview:
This chapter covers fundamental computational structures like Lists, Stacks, Queues, Trees, and Graphs, which form the foundation of all programming and data management systems.
