Which term describes a measure of how many pixels are concentrated in an image?

• A. Resolution
• B. Pixel dimension
• C. Color depth
• D. Aspect ratio

Answer: (A)

Resolution describes how many pixels are packed into an image and thus how much detail it can show. It captures the overall pixel quantity across width and height (like 1920×1080) and, for prints or dense displays, the density of those pixels per inch (PPI). A higher resolution means more pixels in the same area, giving crisper detail when viewed up close or enlarged. Pixel dimension refers specifically to the width and height in pixels, which is part of the picture’s size but doesn’t alone convey how densely those pixels are arranged. Color depth is about how many colors each pixel can display, not how many pixels exist in total. Aspect ratio is the relationship between width and height, not the amount of pixel data.
