RASTER

VECTOR

What are raster files built from?

• Mathematical equations

• Tiny color squares called pixels

• Vector points on a grid

• Infinite lines and curves

Which of the following is a characteristic of vector files?

• They are made up of pixels

• They lose quality when resized

• They can be scaled without impacting quality

• They display a wider array of colors

What happens when you increase the size of a raster image?

• The image can be scaled infinitely without losing quality

• The image becomes blurred or pixelated

• The mathematical formula recalibrates to any size

• The image retains its resolution

Which file type is more suitable for images that need to appear in a high quality regardless of scale?

• GIF

• PNG

• JPEG

• Vector files

What is the resolution of a raster file referred to in?

• RGB (Red, Green, Blue)

• DPI (Dots per inch) or PPI (Pixels per inch)

• CMYK (Cyan, Magenta, Yellow, Key)

• Mathematical formulas

What type of files are digital photographs usually saved as?

• Vector files

• Raster files

• Audio files

• Document files

Why do vector files work better for digital illustrations and logos?

• Because they are larger in size

• Because they can contain millions of pixels

• Because the resolution of vectors remains the same when resized

• Because they are easier to compress

What is a common use for raster files?

• Editing text documents

• Editing images, photos, and graphics

• Storing high-quality audio

• Creating complex animations

What is a benefit of vector files compared to raster files?

• They are generally larger

• They contain millions of pixels

• They are more lightweight

• They slow down page loading speeds
