Tree

A tree is a type of knowledge-base/docs/Public/Tech/Software/Theory/graph data structure that has a hierarchical "tree" structure. A knowledge-base/docs/Public/Tech/Software/Theory/root node "branches" off to its connected children nodes, and those nodes act as a parent node to other children nodes. You can traverse through the tree from the root to any node in a unique path in one direction.

Trees can be used to store data that has an inherent hierarchical structure i.e. directories, files, and folders in file management systems. ¹

Trees are easy to sort and search through using algorithms.
