Processing nodes in a graph one at a time, usually in some specified order. Traversal of a tree is recursively defined to mean visiting the root node and traversing its children. Visiting a node usually involves transforming it in some way or collecting data from it.

In "pre-order traversal", a node is visited __before__ its children. In "post-order" traversal, a node is visited __after__ its children. The more rarely used "in-order" traversal is generally applicable only to binary trees, and is where you visit first a node's left child, then the node itself, and then its right child.

For the binary tree:

T / I S / D E

A pre-order traversal visits the nodes in the order T I D E S. A post-order traversal visits them in the order D E I S T. An in-order traversal visits them in the order D I E T S.
