Which basic operation allows recalling previous data?

• A. Input
• B. Processing
• C. Output
• D. Storage

Answer: (D)

Recalling previous data comes from storage. Storage is the part of a computer that keeps information so you can get it back later. When you save a file, you’re putting data into storage, and later you can retrieve it to view or edit again. Input is simply bringing new data into the system, processing is changing or computing that data, and output is presenting results to you. For long-term recall, non-volatile storage like a hard drive or SSD is used; RAM stores data only briefly while a program runs. So, the capability that makes remembering or reusing earlier data possible is storage.
