informationstragenden

Informationstragende is a German term used to describe entities that carry information: things that encode, store, or convey data so that others can interpret or process it. The concept is applied across several disciplines, including information theory, linguistics, biology, and media studies. A carrier can be physical, digital, or abstract, but its defining feature is its capacity to hold a representation of information and to enable its transmission or retrieval.

Common examples include printed text, signs, magnetic tapes, hard disks, electrical or optical signals, and biological molecules such as DNA or proteins. In social communication, language and symbols function as information carriers; in biology, DNA transmits genetic information; in computing, storage media and communication channels serve as carriers that enable data persistence and transfer.

Key properties of informationstragende include capacity (how much information can be stored or transmitted), fidelity (the accuracy of information after storage or transmission), redundancy (extra information that supports error detection and correction), and durability under environmental conditions. Information theory, notably Shannon’s framework, analyzes the limits of capacity and reliability of carriers and channels, accounting for noise and the role of error-correcting codes.

The concept is relevant for the design of communication systems, libraries and archives, data storage technologies, and emerging areas such as DNA-based data storage and quantum information carriers. Recognizing informationstragende helps to understand how information exists, moves, and persists across diverse media and contexts.
