A screen shot is the action of capturing an image from the screen of a computer monitor or another electronic device to a static image file. It is a way to take a picture of an image from a monitor or screen.
Screen shots can help people understand things that are otherwise hard to explain. For example, screen shots could be used to display an incomplete project that is in progress. This is useful for software that needs approval before it is finished. It also lets users save images appearing on their computer screens without printing them. Screen shots allow users to save these images for future reference.
