Chapter 23: Visual Communication — Important Questions & Answers
Which of the following is a key characteristic of raster graphics?
- A. They are resolution dependent and made of pixels.
- B. They are based on mathematical equations.
- C. They do not lose quality when scaled.
- D. They are always vector-based.
Answer: A. They are resolution dependent and made of pixels.
Raster graphics are composed of a grid of pixels and lose quality when enlarged (pixelation).

What is the primary function of a timeline in video editing software?
- A. To store raw image files.
- B. To arrange video clips and audio tracks in a sequential order.
- C. To change the resolution of the screen.
- D. To render 3D vector images.
Answer: B. To arrange video clips and audio tracks in a sequential order.
The timeline is the workspace where video and audio clips are organized and trimmed to create the final movie.

If you want to create a logo that can be scaled to any size without losing quality, which format should you use?
- A. JPEG
- B. PNG
- C. Vector (SVG)
- D. BMP
Answer: C. Vector (SVG)
Vector graphics are based on mathematical paths, allowing them to be scaled infinitely without loss of quality.

Compare Raster vs. Vector: Why would a designer choose a Vector format for a billboard design?
- A. Vectors are smaller in file size for high resolution.
- B. Vectors preserve mathematical properties, maintaining sharpness at large scales.
- C. Vectors support better shadow effects than rasters.
- D. Billboards are always displayed on digital screens using pixels.
Answer: B. Vectors preserve mathematical properties, maintaining sharpness at large scales.
Vectors use mathematical formulas to render shapes, making them superior for large-scale printing where resolution needs to be sharp.

Why is 'lossless compression' preferred for professional image archiving despite larger file sizes?
- A. It uses fewer colors, making the image clearer.
- B. It allows for perfect restoration of the original data without degradation.
- C. It is faster to upload to social media platforms.
- D. It automatically converts vector images to raster.
Answer: B. It allows for perfect restoration of the original data without degradation.
Lossless compression removes redundancy without losing any original data, ensuring high fidelity for professional archiving.
