DataCom 2

Shannon stated that the amount of knowledge in a signal is not determined by the message's size.

• TRUE

• FALSE

In information theory, the amount of information in a message is often referred to as its "information content" or ____.

Which of the following are examples of error correction codes?

• Reed-Solomon

  codes.

• Morse Code

• EBCDIC code

• Hamming codes

He is an American mathematician and electrical engineer, computer scientist and cryptographer. He is known as the "father of information theory''.

The more surprising or unexpected a message is, the more information it contains.

Conversely, if a message is highly predictable, it contains less information. Give an example.

Evaluate responses using AI:

OFF

It is a way to measure the uncertainty or unpredictability in a message or data source. It quantifies the average amount of information per symbol or character in a message.

It is the basic unit used to measure information.

Its goal is to represent data in a way that minimizes the number of bits required to transmit or store it, while retaining its essential information content.

• machine learning

• cryptography

• data compression

• communication

In lossy compression, some information is intentionally discarded to achieve higher compression ratios. This is commonly used in multimedia applications. Give an example.

Evaluate responses using AI:

OFF

Which of the following is not one of the factors affecting channel capacity?

• Bandwidth

• Entropy

• Signal-to-Noise Ratio

• Error Probability
