In information theory, the Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise.

What is Shannon's theory of communication?
His ground-breaking approach introduced a simple abstraction of human communication, called the channel. Shannon's communication channel consisted of a sender (a source of information), a transmission medium (with noise and distortion), and a receiver (whose goal is to reconstruct the sender's messages).
What is the Shannon first theorem?
Theorem 1 (Shannon's Source Coding Thoerem): Given a categorical random variable X over a finite source alphabet X and a code alphabet A, then for all uniquely decodable C:X→A∗, it holds that E[|C(X)|]≥H(X).
What does Shannon have to say about the relationship between information and meaning?
“Shannon's theory defines information as a probability function with no dimension, no materiality, and no necessary connection with meaning. It is a pattern not a presence [6]”. The lack of a necessary connection to meaning of Shannon information is what distinguishes it from biotic information.
Who is the father of information theory?
The American mathematician and computer scientist who conceived and laid the foundations for information theory. His theories laid the groundwork for the electronic communications networks that now lace the earth. Claude Elwood Shannon was born on April 30, 1916 in Petoskey, Michigan.
