If you’re displaying a widescreen movie (16:9) on a system that is set up to display 4:3, what will the image look like?
Correct Answer
D. The image will be stretched vertically
Explanation
When displaying a widescreen movie with a 16:9 aspect ratio on a system that is set up to display in 4:3 aspect ratio, the image will be stretched vertically.

What will it sound like if the audio system is overdriven?
Correct Answer
C. Some audio sources will sound distorted
Explanation
When an audio system is overdriven, it means that the volume or power level is set too high, causing the audio to exceed its maximum capacity. This can result in distortion, where the sound becomes fuzzy, clipped, or muffled. Some audio sources, such as speakers or instruments, may be more prone to distortion when overdriven compared to others. Therefore, the correct answer is that some audio sources will sound distorted.
26.
What does it mean for the audio system to be overdriven?

Of component, composite and s-video, which delivers the highest resolution?
Correct Answer
B. Component
Explanation
Component delivers the highest resolution among S-Video, component, and composite. Component video separates the video signal into three components: red, green, and blue. This allows for higher quality and sharper images compared to composite video, which combines all the video signals into one. S-Video, on the other hand, separates the video signal into two components: luminance (brightness) and chrominance (color), resulting in a lower resolution compared to component video.
