Understanding Trees and Binary Trees

This video is part of a series on data structures, focusing on trees and binary trees. It explains the fundamental concepts of tree data structures, including nodes, pointers, root nodes, and leaf nodes. The video also covers binary trees, a special type of graph where each node has up to two pointers. It discusses how binary trees can be represented in memory and their applications in computer science, such as database management, networking, and compression algorithms. The video concludes with a key question about the functioning of trees and binary trees.
