What does megapixel mean?

• A. One million bytes
• B. One million pixels
• C. One thousand pixels
• D. Ten million pixels

Answer: (B)

Megapixel describes the amount of picture detail by counting pixels. One megapixel equals one million pixels, so it’s a measure of image resolution, not the amount of data or file size. That’s why the correct answer is one million pixels. The other options don’t fit: bytes measure data storage, not image detail; one thousand pixels would be an extremely low resolution; ten million pixels would be ten megapixels, not the singular definition of a megapixel. In practice, cameras and phones advertise megapixel counts to indicate how many pixels a photo contains, which correlates with potential detail when you view the image at larger sizes.
