Multimedia Networking Quiz

What is the primary unit used to measure network bandwidth?

• Hertz (Hz)

• Bits per second (bps)

• Megabytes (MB)

• Milliseconds (ms)

A higher bandwidth network indicates:

• Slower data transfer speed

• Faster data transfer speed

• No impact on transfer speed

• Increased latency

Which of the following activities consumes the most bandwidth?

• Sending a text message

• Browsing a website with images

• Streaming high-definition video

• Checking email

What is a consequence of insufficient bandwidth for a network?

• Improved data security

• Faster loading times

• Slower data transfer speeds and potential congestion

• No impact on network performance

The minimum sampling rate required to avoid aliasing in an audio signal is determined by:

• The desired audio quality

• The signal's average amplitude

• Twice the highest frequency present in the signal

• The bit depth used for quantization

What is the effect of using a sampling rate lower than the Nyquist rate?

• The audio signal becomes clearer.

• High-frequency components are accurately captured.

• Introduction of aliasing, where high frequencies appear as lower frequencies.

• No significant change in audio quality.

What is the primary purpose of quantization in an audio signal?

• To amplify the signal strength

• To convert a continuous-amplitude signal into a discrete-amplitude representation

• To remove noise from the audio

• To compress the size of the audio file

Quantization introduces:

• Increased audio quality

• A slight loss of information

• No change to the signal

• Improved data transmission speed

In the context of multimedia networking, what does the term ‘entropy encoding’ refer to?

• A method of compressing data by reducing redundancy

• A technique for encrypting multimedia data

• A protocol for real-time streaming

• A type of error correction code

What is Shannon-Fano encoding?

• A lossless data compression technique

• A lossy data compression technique

• A data encryption technique

• A data transmission protocol
