"Communication Theory of Secrecy Systems" is a paper published in 1949 by Claude Shannon discussing cryptography from the viewpoint of information theory. [1] It is one of the foundational treatments (arguably the foundational treatment) of modern cryptography. [ 2 ]
Epistemic closure [1] is a property of some belief systems.It is the principle that if a subject knows , and knows that entails, then can thereby come to know .Most epistemological theories involve a closure principle and many skeptical arguments assume a closure principle.
The law is, in a strict sense, only about correspondence; it does not state that communication structure is the cause of system structure, merely describes the connection. Different commentators have taken various positions on the direction of causality; that technical design causes the organization to restructure to fit, [ 10 ] that the ...
A speech code can also be defined as "a historically enacted socially constructed system of terms, meanings, premises, and rules, pertaining to communicative conduct." [ 1 ] "This theory seeks to answer questions about the existence of speech codes, their substance, the way they can be discovered, and their force upon people within a culture ...
Theism is broadly defined as the belief in the existence of at least one deity. [ 1 ] [ 2 ] In common parlance, or when contrasted with deism , the term often describes the philosophical conception of God that is found in classical theism —or the conception found in monotheism —or gods found in polytheistic religions—or a belief in God or ...
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
A diagram demonstrating the principle of triadic closure. If A is linked to B, and A is also linked to C, then there is a tendency for B to become linked to C. Triadic closure is a concept in social network theory, first suggested by German sociologist Georg Simmel in his 1908 book Soziologie [Sociology: Investigations on the Forms of Sociation ...
An open system is defined as a "system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components." [4] For example, living organism. Closed systems, on the other hand, are considered to be isolated from their environment.
