Name two input devices and two output devices, and give a typical primary use for each.

• A. Input: Keyboard (text entry), Mouse (pointer control). Output: Monitor (display), Printer (hard copy output).
• B. Input: Monitor (display), Printer (hard copy); Output: Keyboard (text entry), Mouse (pointer control).
• C. Input: Microphone (sound input), Scanner (image input); Output: Speakers (audio output), Projector (video output).
• D. Input: Keyboard (text entry), Mouse (pointer control). Output: USB drive (data storage), Network cable (data transfer).

Answer: (A)

Understanding which devices take information into a computer versus which ones show or produce results is essential. Two common input devices are the keyboard, used for typing text, and the mouse, used for moving a cursor and making selections. Two common output devices are the monitor, which displays information on the screen, and the printer, which produces a physical hard copy of what you see on the screen. This pairing uses the most familiar, straightforward examples of input and output, illustrating how data travels into the system and how results come back out. While other options can involve valid devices, they often mix roles or rely on less typical peripherals, making the clear, everyday set—keyboard and mouse for input, monitor and printer for output—the best choice.
