What is resolution in digital images?

• A. Concentration of pixels in an image
• B. The physical size of the image
• C. The color depth
• D. The frame rate

Answer: (A)

Resolution is the concentration of pixels in an image. It describes how many pixels are packed into a given area, which determines how much detail the image can show. A higher resolution means more pixels per unit area, producing a crisper, more detailed picture on screen or in print. The physical size of the image or printing area can change how large it appears, but resolution itself is about pixel density. Color depth relates to how many colors each pixel can display, and frame rate is about motion in video, so neither describes how detailed a still image is.
