ELI5: Explain Like I'm 5

Print screen

Print screen is like taking a picture of what you see on the computer screen. Just like how you take pictures with a camera, you can take a picture of whatever you see on the computer. When you press the print screen button on the keyboard, it captures everything you see on the screen and saves it in the computer's memory. Then, you can paste it somewhere, like in a document or an email or on Paint, to see the picture of what was on your computer screen. This way, you can always have a copy of what you see on your computer.
