Give at least one way that terminal-digit and middle-digit numbering are alike and one way that they are different.

Terminal digit filing is a filing system that works by means of the last two numbers on files to consolidate them. While middle digit filling uses a tripartite number, using the first part of the number for the second sort, middle part for the initial sort, and the third portion for the final sort. One way they are similar is that the two evade working with large numbers and overpowers the difficulties of crowding at the end of the storage.
