kommunikasjoner

Kommunikasjoner is a general term for the process of transmitting information between agents through signs, symbols, or signals. The field encompasses both human-mediated and machine-mediated exchanges and includes spoken and written language, nonverbal cues, and digital data. The objective is to convey meaning, intent, or data across distances or barriers, and to permit feedback to adjust the message.

Core concepts include sender, message, channel or medium, receiver, feedback, context, and noise. Encoding and decoding are cognitive steps in which ideas are translated into signals and back into meaning. The Shannon–Weaver model and related information theory frameworks describe how information is transmitted, the impact of noise, and the limits of communication channels.

Subfields and technologies include telecommunications, computer networks, wireless and mobile communications, internet protocols, broadcasting (radio and television), data storage and retrieval, and postal/courier services. ICT (information and communications technology) combines computing, communications, and data management to support organizational and societal functions.

Applications span education, business, government, media, health care, and emergency services. Challenges include privacy and security, data protection, surveillance, regulation, and the digital divide. Standards and interoperability efforts (such as open standards and common protocols) aim to ensure reliable cross-system communication. Infrastructure considerations include submarine cables, terrestrial networks, satellites, data centers, and cloud services.

Geopolitically and economically, communications networks shape information flows, market competition, and cultural exchange. The field continually evolves with advances in wireless technologies, fiber optics, encryption, and artificial intelligence, which influence both the capacity and governance of kommunikasjoner across societies.
