It contributed to computer science. Les notions proposées par Shannon ont été popularisées (après relecture par Shannon) par John Robinson Pierce dans son ouvrage de vulgarisation An Introduction to Information Theory : Symbols, Signals, and Noise[13]. A basis for such a theory is contained in the important papers of Nyquist 1 and Hartley 2 on this subject. A basis for such a theory is contained in the important papers of Nyquist 1 and Hartley 2 on this subject. Il pose les éléments de base de la théorie de la communication : Dans l'article, il introduit le mot « bit » (qu'il attribue au mathématicien John Tukey) en tant qu'unité d'information[12]. L'article de Shannon a notablement influencé l'étude de la transmission et de la réception de l'information[7],[8].

A Mathematical Theory of Communication By C. E. SHANNON INTRODUCTION T HE recent development of various methods of modulation such as PCM and PPM which exchange bandwidth for signal-to-noise ratio has intensified the interest in a general theory of communication. This theory was essential in enabling telecommunications to move from analog to digital transmissions systems in the 1960s and later. And in making 'information' 'measurable' it gave birth to the mathematical study of 'information theory', According to Robert T. Craig in his foundational publication, Communication Theory as a Field (1999), communication theory “consist of seven traditions that are […] characteristic of the field: rhetoric, semiotics, phenomenology, cybernetics, sociopsychology, sociocultural theory, and the critical approach.”, "Communication is a process of expression, interaction, and influence, in which the behavior of humans or other complex organisms expresses psychological mechanisms, states, and traits and, through interaction with the similar expressions of other individuals, produces a range of cognitive, emotional, and behavioral effects.” (Craig, 1999, p. 143). [International Association of Communication Activist 1], Basic elements of communication made the object of study of the communication theory:[4], This article is about the discipline. The origins of communication theory is linked to the development of information theory in the early 1920s. [1] Shannon focused on the problem of how best to encode the information that a sender wants to transmit. He is also credited with the introduction of sampling theory, which is concerned with representing a continuous-time signal from a (uniform) discrete set of samples. Il constitue le fondement théorique de la théorie de l'information et, par ricochet, il a marqué la théorie des télécommunications. The main landmark event that opened the way to the development of communication theory was the publication of an article by Claude Shannon (1916–2001) in the Bell System Technical Journal in July and October 1948 under the title "A Mathematical Theory of Communication".

Ralph Hartley's 1928 paper, Transmission of Information, uses the word "information" as a measurable quantity, reflecting the receiver's ability to distinguish one sequence of symbols from any other. Communication channels are also studied in a discrete-alphabet setting. Questo lavoro viene considerato una delle ricerche che fondarono la moderna teoria dell'informazione.Nell'articolo Shannon definì i componenti base delle comunicazioni digitali: . Scientific knowledge grows at a phenomenal pace--but few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication, published originally as a paper on communication theory more than fifty years ago. 3rd Edition, New York, NY; Oxford University Press, 2010. A Mathematical Theory of Communication is an article by mathematician Claude E. Shannon published in Bell System Technical Journal in 1948. Shannon and Weaver's work proved valuable for communication engineers in dealing with such issues as the capacity of various communication channels in 'bits per second'.
