What resolution determines an image?

The resolution of an image is determined by the number of pixels it contains, typically expressed as width x height (e.g., 1920x1080). Higher resolutions mean more pixels, resulting in finer detail and sharper images. Additionally, resolution can be described in terms of pixel density, measured in pixels per inch (PPI), which influences how the image appears when printed or displayed on screens. Overall, higher resolution enhances the clarity and quality of the image.
