Final answer:
The critical difference between brain and computer memory storage is that a brain's stored information is frequently irretrievable, whereas a computer's stored information is always retrievable.
Step-by-step explanation:
The critical difference between the way the brain and computers store memories is that a brain's stored information is frequently irretrievable, whereas a computer's stored information is always retrievable.
A brain's stored information can be affected by aging, brain trauma, and certain disorders, causing it to be inaccessible or difficult to recall.
On the other hand, a computer's stored information can always be retrieved as long as the storage medium remains intact and the data is not corrupted.
