=== Data Type Hiding ===

Since the implementation of a linked list is custom, the programmer may very well implement the list in any way that they may see fit. This effectively hides the data being stored from the watchful eyes of the calling program. As well, the actual location of the data is effectively random (as opposed to being sequential) which means that the data is that much harder to find. This adds a simple layer of security that arrays simply do not afford.
