Information theory is the mathematical study of the quantification, storage, and communication of information. The field was established and put on a firm footing by Claude Shannon in the 1940s, [1] though early contributions were made in the 1920s through the works of Harry Nyquist and Ralph Hartley. It is at the intersection of electronic ...
t. e. Systems theory is the transdisciplinary [ 1] study of systems, i.e. cohesive groups of interrelated, interdependent components that can be natural or artificial. Every system has causal boundaries, is influenced by its context, defined by its structure, function and role, and expressed through its relations with other systems.
An information system ( IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. [ 1] From a sociotechnical perspective, information systems comprise four components: task, people, structure (or roles), and technology. [ 2] Information systems can be defined as an integration of ...
Information science or informatology[ 1][ 2] is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. [ 3]
Development since 1948. The publication of Shannon's 1948 paper, "A Mathematical Theory of Communication", in the Bell System Technical Journal was the founding of information theory as we know it today. Many developments and applications of the theory have taken place since then, which have made many modern devices for data communication and ...
The technology acceptance model ( TAM) is an information systems theory that models how users come to accept and use a technology . The actual system use is the end-point where people use the technology. Behavioral intention is a factor that leads people to use the technology. The behavioral intention (BI) is influenced by the attitude (A ...
Quantum information is the information of the state of a quantum system. It is the basic entity of study in quantum information theory, [ 1][ 2][ 3] and can be manipulated using quantum information processing techniques. Quantum information refers to both the technical definition in terms of Von Neumann entropy and the general computational term.
Integrated information theory ( IIT) proposes a mathematical model for the consciousness of a system. It comprises a framework ultimately intended to explain why some physical systems (such as human brains) are conscious, [1] and to be capable of providing a concrete inference about whether any physical system is conscious, to what degree, and ...
