1. Why might a streaming service choose lossy compression over lossless compression for video streaming?

• Faster load times due to smaller file size
• To ensure the highest possible quality
• To avoid overflow errors
• To ensure compatibility with older devices

2. How does increasing the number of bits used to represent a pixel in an RGB image affect its color range?

• Increases the color range
• Decreases the color range
• The color range remains the same
• The color range becomes binary

3. What potential benefits can an artist gain by choosing a Creative Commons license over traditional copyright?

• Greater exposure and collaboration
• Increased revenue from sales
• Prevention of unauthorized use
• Complete control over the distribution of their work

4. In what scenarios might a digital thermometer's sampling rate be considered insufficient for accurate measurements?

• Rapid temperature fluctuations
• Long-term temperature monitoring
• Recording temperatures in extreme environments
• Measuring the temperature of static objects

5. How can using a lossless compression format for text documents benefit collaboration among team members?

• Ensures the integrity of the document content and formatting
• Allows for smaller file sizes
• Reduces the likelihood of intellectual property theft
• Enables real-time editing capabilities

6. When might a music producer choose to use lossless compression over lossy compression for audio files?

• To preserve the highest audio quality for professional use
• To save storage space
• To make the files compatible with all devices
• To reduce the risk of round-off errors

7. How does the high frame rate of a high-speed camera affect the quality of the digital data captured from analog light data?

• Increases the accuracy of the digital representation
• Decreases the accuracy of the digital representation
• Does not affect the accuracy of the digital representation
• Makes the digital data susceptible to overflow errors

8. In what fields of research might scientists need to be particularly concerned about round-off errors when storing digital data?

• Quantum physics and nanotechnology
• Geology and environmental sciences
• Literature and history
• Business and finance

9. How can the use of bits to represent unique combinations of 0s and 1s in secure messages contribute to the security of the message?

• Allows for data encryption
• Reduces the file size of the message
• Ensures the message is only readable in certain programs
• Prevents unauthorized distribution of the message

10. How can obtaining intellectual property protection for a software invention positively impact a company's business?

• Enhances the company's reputation and potential revenue
• Ensures compatibility with all devices
• Reduces the risk of round-off errors in the software
• Allows for unrestricted distribution of the software
