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 (a) .
Which of the following are examples of error correction codes?
Reed-Solomon
codes.
Morse Code

He is an American mathematician and electrical engineer, computer scientist and cryptographer. He is known as the "father of information theory''.
(a)
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.
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.
(a)
It is the basic unit used to measure information.
(a)
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.
Which of the following is not one of the factors affecting channel capacity?
Bandwidth
Entropy
Signal-to-Noise Ratio
Error Probability
It involves the practice of concealing or encoding information in a manner that ensures only the intended recipient can decipher it.
Decoding
Data compression
Cryptography
Digital signal processing
Give an example of guided or wired transmission media.
Give an example of unguided or wireless transmission media.
This transmission technique allows multiple signals or data streams to share a single communication channel.
(a)
(a) cables are used for cable television (CATV), broadband internet, and some older Ethernet networks.
It is a line-of-sight transmission (unguided) i.e. the sending and receiving antennas need to be properly aligned with each other.
(a)
Give an example of an early form of communication.
UNIVAC I is the very first general-purpose electronic computer.
TRUE
FALSE
He was granted a patent on an electromagnetic telegraph in 1837.
(a)
In 1876, Alexander Graham Bell won the first U.S. patent for what device?
