What data describes other data, such as the size of an image, the number of colors, or the resolution?

• A. Pixel
• B. Metadata
• C. Image
• D. Lossless

Answer: (B)

Metadata is data that describes other data. In an image file, metadata includes details like its size in bytes, dimensions in pixels, color depth or number of colors, and resolution. This descriptive information helps programs know how to display or manage the image without being the actual picture data itself. A pixel is a single point of color within the image, the image itself is the collection of all pixel data, and lossless refers to a way of compressing data without losing information. Therefore, the data that describes the image's properties is metadata.
