Answer:
Encoding failure.
Explanation:
As the example shows, encoding failure occurs when the mind fails to create a memory link, fails to store events or information for it's future recall. Juanita was daydreaming about her college plans during a boring lecture on the history of computers so she does not remember the particular piece of information that ENIAC was the first functioning digital computer because she was not paying attention, she was thinking in something else. Therefore, her brain failed to create this memory link, failed to store the information she needed later.
