Which device allows users to input information into a computer?

The keyboard is the device that allows users to input information into a computer. It consists of keys that represent letters, numbers, and other symbols, enabling users to enter data, execute commands, and interact with software applications. This device is essential for a variety of tasks, including typing documents, entering data in spreadsheets, and navigating the internet.

Monitors, printers, and speakers serve different purposes. Monitors display output from the computer, providing a visual representation of information processed. Printers produce hard copies of digital documents, converting electronic text and images into printed format. Speakers provide audio output, allowing users to hear sounds, music, or other audio from the computer. Each of these devices plays a role in the computing experience, but they do not facilitate user input in the same way that a keyboard does.
