Which term describes the result produced by a system after processing inputs?

• A. Output
• B. Input
• C. Process
• D. Feedback

Answer: (A)

Think of a system as something that takes in inputs, does something to them, and then gives something back. The thing it produces after processing is the output. Input is what you feed into the system, the process is the operation that transforms those inputs, and feedback is information about the output used to adjust the system. For example, a computer program takes data as input, performs calculations (the processing), and shows the result on the screen as output. A printer takes text as input, prints it (the process), and the final printed page is the output.
