<ul><li>Binary trees are like family trees where each node can have up to two children.</li><li>Traversal in binary trees means visiting nodes in a specific order, common types include preorder, inorder, postorder, and level order traversal.</li><li>Different traversal methods have different efficiency and space complexities, from recursive approaches to iterative solutions using stacks.</li><li>Understanding binary trees and their traversals is crucial for programming, practicing both recursive and iterative solutions can enhance coding skills and help in interviews.</li></ul>
