Which basic computer operation provides data to process?

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

Answer: (A)

Providing data to the computer for processing is the role of input. An input operation is how data or signals first enter the system so the processor can work on them. Think of typing on a keyboard, clicking a mouse, scanning a document, or reading a sensor; all of these send data to the computer for processing. The processor can’t do anything until something to work on is supplied, which is why input is the starting point in the data flow. After processing, output delivers the results and storage can save data for later use. Processing is the step that manipulates data already available, storage keeps data for future use, and output presents the results. So the choice describing the step that provides data to process is input.
