... Starting with the root node A we have a choice of B,C and D to expand. We choose B (by our alpha-numeric ordering convention) and place B at top of our stack. Next we consider the children of B and choose E. The children of E are M and N so we choose M. At this point we have reached a leaf node (i.e ...

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
