CMS File Formats and Media Standards 1 — Questions and Answers
Question 1: Which image file format uses lossy compression and is best suited for photographic web images?
- PNG
- JPEG (Correct answer)
- GIF
- BMP
Correct answer: JPEG
JPEG uses lossy compression that reduces file size by discarding some image data, making it ideal for photographs with complex color gradients on the web.
Question 2: Which file format supports both transparency and lossless compression, making it widely used for web graphics with flat colors?
- JPEG
- TIFF
- PNG (Correct answer)
- BMP
Correct answer: PNG
PNG (Portable Network Graphics) supports lossless compression and an alpha channel for transparency, making it ideal for logos and graphics requiring crisp edges.
Question 3: What does the acronym SVG stand for in web and multimedia design?
- Scalable Vector Graphic (Correct answer)
- Standard Video Graphic
- Structured Visual Grid
- System Vector Geometry
Correct answer: Scalable Vector Graphic
SVG stands for Scalable Vector Graphic, an XML-based format that renders crisp at any resolution because it stores paths and shapes rather than pixels.
Question 4: Which video container format was developed by Apple and is the native format for QuickTime media?
- AVI
- MOV (Correct answer)
- MKV
- WMV
Correct answer: MOV
MOV is Apple's QuickTime container format, capable of storing video, audio, and text tracks and is widely used in professional video production on macOS.
Question 5: What is the standard audio sample rate for CD-quality audio?
- 22,050 Hz
- 48,000 Hz
- 44,100 Hz (Correct answer)
- 96,000 Hz
Correct answer: 44,100 Hz
44,100 Hz (44.1 kHz) is the standard sample rate for CD audio, chosen because it exceeds twice the upper limit of human hearing per the Nyquist theorem.
Question 6: Which color profile is the international standard for web content and digital display devices?
- Adobe RGB
- ProPhoto RGB
- sRGB (Correct answer)
- CMYK
Correct answer: sRGB
sRGB (standard Red Green Blue) is the default color space for web browsers, monitors, and consumer digital cameras, ensuring consistent color reproduction across devices.
Question 7: What key advantage does a camera RAW file format provide over JPEG for multimedia professionals?
- Smaller file size for faster upload
- Lossless capture of all sensor data for maximum post-processing flexibility (Correct answer)
- Built-in color correction applied by the camera
- Compatibility with all image viewing software
Correct answer: Lossless capture of all sensor data for maximum post-processing flexibility
RAW files preserve all unprocessed sensor data without in-camera compression or adjustments, giving editors maximum latitude to correct exposure, white balance, and color in post-production.
