A screenshot is an image taken of the computer screen or a portion of the screen. These images can be useful for creating a demonstration of a program or even for recording a problem on your computer. You can easily take a screenshot on a Mac or PC without installing additional software.

For PC

1. On the upper right-hand side of your keyboard, press PrtScn.
2. The screenshot will be copied onto your clipboard. Open any image-editing program like Paint and click on Paste or use the keyboard command: Control-V.
3. Save the image.

For Mac

1. On your keyboard, press Command (Apple Key) – Shift – 3, in this order, to capture the entire screen.  Or press, Command – Shift – 4 to highlight and select an area of the screen to capture.
2. The image will be saved to your desktop.
