    • Array of samples
    • List of objects

  2. Which property is stored for a vector graphic object?

    • Fill colour
    • Pixel array

    • Drawing primitive
    • Bitmap mask

  4. What happens to the image quality when a vector graphic is enlarged?

    • It turns blurry
    • It reduces resolution
    • It is maintained
    • It becomes pixelated

  5. Which type of graphic is best suited to logos and line drawings?

    • Scalable icon
    • Simple flowchart
    • Continuous-tone photograph

  7. Which properties are required to mathematically define a simple vector circle?

    • Pixel density
    • Centre and radius
    • Top-left coordinate
    • Width and height

  8. A vector rectangle has corners (0,0), (10,0), (10,5) and (0,5). What is its area?

    • 30
    • 25
    • 15
    • 50

  9. How is a vector graphic image stored internally in a file?

    • Frequency spectrum
    • Grid of bytes

  11. A vector shape is a square with four sides each of length 5. What is its perimeter?

    • 10
    • 15
    • 20
    • 25

  12. Why does a plain square usually have a smaller file size as a vector than a bitmap?

    • Fewer stored properties
    • Lower colour depth

    • 16
    • 8
    • 2
    • 4

  16. Why are bitmap graphics preferred over vector graphics for complex photographic images?

    • Smaller file size
    • Resolution independence
    • Fine tonal detail
    • Infinite scalability

  17. What visual artefact appears on a bitmap image when it is significantly zoomed in?

    • Colour inversion

  19. What key advantage do vector graphics offer for digital maps that require frequent zooming?

    • Fast bitwise operations
    • Lossy compression
    • Resolution independence
    • Fixed pixel layout

  20. Which operation can be performed on a single shape in a vector graphic without affecting overlapping shapes?

    • Independent editing
    • Pixel resampling
    • Quantisation
    • Direct colour filtering
