    • C.

      A tiny square of color and light

    • D.

      A JPEG

    Correct Answer
    A. A two dimensional mapping of pixels that are themselves made out of bits.
    Explanation
    A digital image is a representation of visual information in a digital form. It consists of a two-dimensional grid of pixels, which are the smallest units of the image. Each pixel is made up of bits, which determine its color or intensity. Therefore, a digital image can be described as a two-dimensional mapping of pixels that are themselves made out of bits.

    How many megapixels would I need to produce an awesome 8x12 print?

    • A.

      12.7

    • B.

      10.5

    • C.

      12.4

    • D.

      18.6

    Correct Answer
    C. 12.4
    Explanation
    To produce an awesome 8x12 print, you would need a camera with at least 12.4 megapixels. This is because the resolution of the image needs to be high enough to capture the fine details and ensure a sharp and clear print at that size. A higher megapixel count allows for more information to be captured, resulting in better image quality and detail.

    Which answer best describes the file format Portable Network Graphics (PNG)?

    • A.

      Very large, not transparent, 8 bit color depth

    • C.

      Small file size, usually associated with a scanned image

    • D.

      Small file, transparent, 24 and 8 bit color depth

    Correct Answer
    D. Small file, transparent, 24 and 8 bit color depth
    Explanation
    The correct answer describes the file format PNG as a small file that is transparent and supports both 24 and 8 bit color depth. PNG files are commonly used for images that require transparency, such as logos or graphics with a transparent background. The file size of PNG images is generally smaller compared to other formats like JPEG, while still maintaining good image quality. Additionally, PNG supports both 24-bit true color and 8-bit indexed color, providing flexibility in terms of color depth.
