 It also makes it easy to place the same data in multiple linked lists.Although with internal storage the same data can be placed in multiple lists by including multiple "next" references in the node data structure, it would then be necessary to create separate routines to add or delete cells based on each field.It is possible to create additional linked lists of elements that use internal storage by using external storage, and having the cells of the additional linked lists store references to the nodes of the linked list containing the data.
