A <strong>binary tree</strong> limits each node to at most two children (left and right). A <strong>binary search tree (BST)</strong> adds an ordering invariant: everything in the left subtree is smaller than the node, everything in the right subtree is larger. That invariant is what makes a balanced BST fast to search.</p>
