Graphical output device

Have you ever seen a picture or a video on a screen like your TV, computer, or phone? The device that shows you those pictures or videos is called a graphical output device, or simply an output device.

Think of it like this: when you draw a picture or write something on a piece of paper, you can see it because it's right in front of you. But when you create something using a computer, you need a way to see it on a screen. That's where an output device comes in.

An output device is like a window that shows you whatever you've created on your computer, but in a way that you can see and understand. It takes the signals that your computer produces and turns them into pictures and videos that you can see.

There are many types of output devices, but some of the most common ones include computer monitors, projectors, TVs, and even some printers. Some output devices are small and portable, like a phone or a tablet, while others are big and stationary, like a TV.

So, the next time you see a picture or a video on a screen, you can remember that you're looking at it through an output device that's turning signals from your computer or device into something that you can see and enjoy!
