Insertions, removals, and retrievals all require transferring information to/from internal memory. Insertions involve adding new data to the external file, removals involve deleting data from the external file, and retrievals involve reading data from the external file into internal memory. Therefore, all three of these operations require accessing and manipulating data in both internal and external memory.
