A screenshot is basically the snap or image of the viewable portion of the display screen. It can be from a computer monitor, mobile phone display, tablet screen or even television output. In our case, it would be the snapshot of the entire monitor screen or a particular open window of an application. When you capture a screen, computer stores it in a temporary storage space in image format. By the use of some software one can retrieve it and save it as an image. Screenshot saved as an image file is used widely in tutorials, tech articles, documentation, software reviews, help files etc.
