The most common device for data input?

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

Answer: (D)

Data input to a computer is most commonly done with a keyboard. It offers fast, direct entry of letters, numbers, and commands and is built into nearly every computer and portable device, making it the standard tool for everyday data entry, programming, and text editing. Other devices have specialized roles—mice are mainly for navigation and interaction, scanners convert printed material to digital form, and microphones capture audio for voice input—so while useful, they don’t match the keyboard’s ubiquity and versatility for general data entry.
