Knowra Claude Shannon Claude Shannon Claude Shannon was an American mathematician and electrical engineer whose work founded information theory and established Boolean algebra as a basis for digital circuit design.
Norbert Wiener : Norbert Wiener was an American mathematician who founded cybernetics, the study of control and communication in animals and machines. Shannon and Wiener developed influential but distinct mathematical accounts of communication and control.
Boolean algebra : Boolean algebra is a system of logic using values such as true and false and operations such as AND, OR, and NOT. Shannon showed that Boolean algebra describes the behavior of relay and switching circuits.
Digital circuit : A digital circuit processes information using discrete voltage states, commonly interpreted as binary values. Shannon’s switching-circuit analysis supplied a mathematical method for designing these systems.
Bell Labs : Bell Labs was an industrial research laboratory that produced major advances in telecommunications, electronics, and computing. Shannon developed much of his information theory while working at Bell Labs.
Digital revolution : The digital revolution is the transformation of communication, computing, and daily life through digital technologies. Shannon’s mathematical foundations helped make reliable digital storage and communication technically achievable.
Vannevar Bush : Vannevar Bush was an American engineer and science administrator who designed the differential analyzer and led wartime research. Shannon worked on Bush’s differential analyzer at MIT, where its switching circuits shaped his master’s thesis.
Information theory : Information theory is the mathematical study of information, its representation, compression, and transmission through noisy channels. Shannon founded this field by defining information quantitatively and deriving limits on communication.
Shannon–Fano coding : Shannon–Fano coding is a variable-length, prefix-free method for compressing symbols according to their probabilities. Shannon developed this early coding method to represent common symbols with fewer bits.
A Symbolic Analysis of Relay and Switching Circuits : A Symbolic Analysis of Relay and Switching Circuits is Shannon’s 1938 master’s thesis applying Boolean algebra to electrical switching networks. This thesis made the connection between symbolic logic and circuit design explicit.
Shannon limit : The Shannon limit is a theoretical bound on the performance of reliable communication over a noisy channel. It defines how far practical communication systems can improve before reaching Shannon’s fundamental limit.
