Final answer:
Federal records have two disposition types: permanent retention for records of enduring value, and temporary retention for non-essential records that can be destroyed after a certain period.
Step-by-step explanation:
The two types of disposition for federal records are permanent retention and temporary retention. Permanent retention is used for records that have been determined to have enduring historical, cultural, or legal value and are to be preserved indefinitely, often transferred to the National Archives. On the other hand, temporary retention refers to records that are important for a certain period for operational, legal, or regulatory reasons but can be destroyed after they are no longer needed or after that period expires.
