What does the term “resolution” refer to in digital images?

The term "resolution" in the context of digital images primarily refers to the detail an image holds, especially in terms of print quality. A higher resolution means that there are more pixels per inch (PPI), resulting in sharper and clearer images when they are printed. This is crucial for ensuring that images maintain their quality and do not appear pixelated or blurry when enlarged or printed at high sizes.

While file size, color depth, and image dimensions are important aspects of digital images, they do not specifically define resolution. File size relates to how much storage space an image occupies, color depth pertains to the number of colors that can be represented in an image, and image dimensions denote the width and height of the image in pixels. These factors can indirectly affect the perceived resolution but do not embody the term itself as "resolution" specifically focuses on detail and clarity in print output.
