            1. Memory Systems
              1. Caching Strategies
              2. External Searching and B-Trees
                1. (a,b) Trees
                  1. Multiway search tree such that each node has between a and b children and stores between a−1 and b−1 entries.
                  2. B-Trees
                    1. A version of the (a,b) tree data structure, which is the best-known method for maintaining a map in external memory.
                  3. External-Memory Sorting
                    1. Multiway Merge-Sort
                      1. The main idea behind this variation is to merge many recursively sorted lists at a time, thereby reducing the number of levels of recursion.
