What is a Screenshot?


According to Wikipedia, a screenshot is an image taken by the computer to record the visible items displayed on the monitor or another visual output device.

There are three types of screenshots, and these terms are often used interchangeably:

Screenshot
Outputting the entire screen in a common bitmap image format such as BMP, PNG, or JPEG.

Screen dump
The display system dumps what it is using internally upon request, such as XWD X Window Dump image data in the case of X11 or PNG in the case of Mac OS X.

Screen capture (screencaps)
Capturing the screen over an extended period of time to form a video file. (see video capture)
