Which device is a common input device for typing text?

• A. Keyboard
• B. Monitor
• C. Printer
• D. Speaker

Answer: (A)

Typing text relies on a device that sends characters into the computer. The keyboard is designed for this purpose: each keypress creates a signal that represents a character or command, letting you input letters, numbers, and controls directly into the system. The monitor, printer, and speaker, by contrast, are output devices—they display, reproduce on paper, or play audio based on what the computer processes, but they don’t provide the actual text input. So the keyboard is the primary tool for typing text.
