What traversal means

Binary tree with root A, children B and C, grandchildren D E F G, and the three traversal outputs listed beside it

A tree stores data in a hierarchy, where each item is a node connected by edges. The top node is the root, a node with no children is a leaf, and any node plus everything below it is a subtree.
