I learned that depth and height are properties of a node:

The depth of a node is the number of edges from the node to the tree’s root node.A root node will have a depth of 0.

The height of a node is the number of edges on the longest path from the node to a leaf.A leaf node will have a height of 0.

Properties of a tree:

The height of a tree would be the height of its root node,or equivalently, the depth of its deepest node.

The diameter (or width) of a tree is the number of nodes on the longest path between any two leaf nodes. The tree below has a diameter of 6 nodes.

height and depth of a tree is equal…

but height and depth of a node is not equal because…

the height is calculated by traversing from the given node to the deepest possible leaf.

depth is calculated from traversal from root to the given node…..
