Which of the following is an example of an input device?

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

Answer: (C)

The keyboard is an example of an input device because it is designed to allow users to enter data and commands into a computer system. Input devices are essential for interacting with computers, enabling the user to give commands and provide information. When a user presses a key on the keyboard, it sends a signal to the computer, allowing it to process that input. In contrast, the other choices are output devices. A printer produces physical copies of documents, a monitor displays visual output for the user to see, and speakers output sound. These devices do not allow for data entry into the computer; instead, they take information processed by the computer and present it in a format that users can perceive. Thus, the keyboard stands out as the only input device in the list.
