In Network Information Theory, what is the measure of the uncertainty associated with a random variable?

  1. Entropy

  2. Mutual Information

  3. Channel Capacity

  4. Coding Theorem


Correct Option: A
Explanation:

Entropy is a fundamental concept in information theory that quantifies the uncertainty associated with a random variable. It is measured in bits and represents the average amount of information contained in a message.

What is the maximum rate at which information can be transmitted over a channel without errors?

  1. Entropy

  2. Mutual Information

  3. Channel Capacity

  4. Coding Theorem


Correct Option: C
Explanation:

Channel capacity is the maximum rate at which information can be transmitted over a channel without errors. It is measured in bits per second and depends on the characteristics of the channel, such as bandwidth and noise level.

Which coding theorem states that the channel capacity can be achieved using appropriate coding techniques?

  1. Shannon's Source Coding Theorem

  2. Shannon's Channel Coding Theorem

  3. Coding Theorem for Noisy Channels

  4. Coding Theorem for Noiseless Channels


Correct Option: B
Explanation:

Shannon's Channel Coding Theorem states that the channel capacity can be achieved using appropriate coding techniques, even in the presence of noise. This theorem is fundamental to the design of reliable communication systems.

What is the measure of the amount of information that two random variables share?

  1. Entropy

  2. Mutual Information

  3. Channel Capacity

  4. Coding Theorem


Correct Option: B
Explanation:

Mutual information is a measure of the amount of information that two random variables share. It is measured in bits and represents the reduction in uncertainty about one random variable when the other random variable is known.

Which coding theorem states that the entropy of a source can be compressed without loss of information?

  1. Shannon's Source Coding Theorem

  2. Shannon's Channel Coding Theorem

  3. Coding Theorem for Noisy Channels

  4. Coding Theorem for Noiseless Channels


Correct Option: A
Explanation:

Shannon's Source Coding Theorem states that the entropy of a source can be compressed without loss of information. This theorem is fundamental to the design of lossless data compression algorithms.

What is the maximum rate at which information can be transmitted over a noiseless channel?

  1. Entropy

  2. Mutual Information

  3. Channel Capacity

  4. Coding Theorem


Correct Option: C
Explanation:

For a noiseless channel, the channel capacity is equal to the bandwidth of the channel. This means that the maximum rate at which information can be transmitted over a noiseless channel is equal to the bandwidth of the channel.

Which coding theorem states that the channel capacity can be achieved using appropriate coding techniques, even in the presence of noise?

  1. Shannon's Source Coding Theorem

  2. Shannon's Channel Coding Theorem
