Answer:The monitor is an output device that displays information in a visual format. As it said, its function is to display information. A monitor is important because it's how the user will see what they are doing in a visual format.
It shows images, videos, text, and the user interface, allowing people to interact with the computer system. Essentially, it acts as the screen where you see everything you are working on or viewing. Without a monitor, it would be impossible to see the results of your commands or the programs running on your device. Monitors come in different sizes and resolutions but all serve the purpose of making digital information visible.
