Which of the following is a function of a keyboard?

• A. Display graphics
• B. Input user commands
• C. Output data
• D. Store information

Answer: (B)

A keyboard primarily serves the function of inputting user commands and data into a computer or device. This is achieved through a variety of keys that allow users to enter text, numbers, and various commands. When a key is pressed, it sends a signal to the computer, registering the input. Understanding the roles of other choices helps clarify why inputting user commands is the primary function of a keyboard. Displaying graphics is handled by monitors or screens, as they are designated for visual output. Outputting data is also a task for devices like printers or speakers, which communicate processed information to the user in a tangible or audible format. Similarly, storing information is the job of storage devices such as hard drives or SSDs, rather than a keyboard. Therefore, the primary role of a keyboard is to facilitate user interaction by accepting input commands.
