Which input device is most commonly used to enter text and commands?

• A. Keyboard
• B. Mouse
• C. Scanner
• D. Microphone

Answer: (A)

The key idea here is how users input text and commands into a computer. The keyboard is designed specifically for entering characters, numbers, and control commands, making it the primary tool for typing text and issuing keyboard shortcuts (like Enter, Copy, Paste, and various function keys). Because of this, it’s the most common input device for everyday text entry and command input across software and operating systems. The other devices have different strengths but aren’t used as the main means for typing. A mouse is mainly for pointing, selecting, and triggering actions in a graphical interface. A scanner turns physical documents into digital form, but you typically still need another step (like OCR) to turn that into editable text. A microphone can handle voice input and commands, but voice input isn’t as ubiquitous for text entry or precise command execution in many contexts. So, the input device most commonly used to enter text and commands is the keyboard.
