A screen shot is a digital image or photograph of what appears on an electronic device's display screen. It captures and preserves the visual appearance of a website, document, app, or any other content that can be displayed on a monitor, tablet or smartphone. Screen shots are often used to provide visual evidence of something seen on a computer or mobile device, such as an error message, web page, or text conversation. They can also serve as a quick way to capture and share information, ideas, or instructions without having to type them out or write them down.
