What does the term resolution refers to the number of pixel presented how?

Resolution refers to the number of pixels displayed in a digital image or screen, typically expressed as width x height (e.g., 1920 x 1080). A higher resolution means more pixels are used to create the image, resulting in finer detail and clarity. For example, a 4K resolution (3840 x 2160) provides four times the pixel count of Full HD (1920 x 1080), enhancing the visual experience.
