The keyboard is an example of an input device because it is used to enter data and commands into a computer system. Input devices are essential for user interaction with computers, allowing users to provide information, control commands, or communicate with the system. A keyboard specifically allows for text input, enabling users to type documents, execute commands, and navigate through applications.

In contrast, a monitor is an output device that displays visual information from the computer, while a printer also serves as an output device by producing a physical copy of digital documents and images. A scanner, although it captures physical documents and converts them into digital data, is not the best choice in this context as it is used for input of images rather than text or commands directly. Overall, the keyboard stands out as a primary input tool for direct user interaction.
