Quiz on Data Streaming Concepts

What is the primary difference between real-time streaming and on-demand streaming?

• Real-time streaming involves pre-recorded content, while on-demand streaming happens live.

• Real-time streaming occurs as events happen, while on-demand streaming delivers pre-recorded content.

• Real-time streaming does not require compression, whereas on-demand streaming does.

• Real-time streaming is only used for audio, and on-demand streaming is only used for video.

What happens when the bit rate required for a video exceeds the available bandwidth?

• The video quality improves.

• The streaming speed increases.

• The video may buffer, freeze, or display reduced quality.

• The streaming automatically switches to audio-only mode.

Which of the following requires the highest bit rate?

• Standard-definition video

• High-definition (HD) video

• Ultra-high-definition (UHD) video

• Audio-only streaming

Why is compression important for streaming media?

• It removes unnecessary audio tracks.

• It increases the file size for smoother streaming.

• It reduces file sizes, making it possible to stream media over standard internet connections.

• It eliminates buffering entirely.

What role does a buffer play during streaming?

• It improves the resolution of the video.

• It acts as a backup storage for downloaded content.

• It stores extra data temporarily to ensure smooth playback during connection interruptions.

• It increases the bit rate of the streamed content.

Which of the following is more sensitive to poor quality during streaming?

• Video

• Audio

• Both are equally sensitive

• Neither is sensitive

If your internet bandwidth is 5 Mbit/s, which of the following can you stream smoothly without buffering?

• UHD video

• HD video

• SD video

• None of the above

What is a key limitation of mobile data connections like 3G for streaming?

• They do not support any type of streaming.

• They cannot meet the bit rate requirements for HD or UHD content.

• They only support on-demand streaming.

• They have built-in compression that reduces quality.

Which codec might Netflix use to compress a video for streaming?

• H.264

• MP3

• FLAC

• JPEG

What would happen if streaming a movie in HD (bit rate ~5 Mbit/s) on a 10 Mbit/s internet connection?

• The video will buffer continuously.

• The playback will be smooth, with a buffer storing extra content.

• The quality will automatically reduce to SD.

• The video will not play due to low bandwidth.
