Digital information

from Wikipedia, the free encyclopedia

Digital information is information that is described by digits. This can e.g. B. in the dual system with the digits 0 and 1. Computer technology is based on the processing of digital information. The digital representation of information facilitates the calculation of statistical properties in information theory . The digital output of information can be described as follows: “Representation of the data by finite character strings, whereby the characters used come from an (agreed) finite set. [...] binary representation "

background

With the spread of computers, which can most easily interpret systems that only work with two different states, such as no and yes , on and off or 0 and 1 , digitization was also introduced. In 1999 Rafael Capurro wrote in his essay on the "Digital World Design":

“The understanding of being has changed. In contrast to the modern conception based on empirical perception, according to which the being of things is inseparable from perception (Kant), and is even identical to being perceived "Their esse is percipi" (Berkeley 1965, 62), the following applies: now: eat est computari. The world is everything that can be digitized. "

- Rafael Capurro: Digital world design. An essay with Heideggerian intent. 1999.

The digital information can be represented as a sequence of 0 and 1 or, more generally, as a sequence of binary numerical values. There are a large number of projects that specialize, for example, in the digital reproduction of printed works of literature and make them available in digital form after the copyrights have expired . These include:

Shipbuilding plans , for example, are also created in digital form. Another area of ​​digital information is media from the field of music, video, photography or in science. For this purpose, the Alexander von Humboldt Foundation , the German Research Foundation (DFG), the German Academic Exchange Service (DAAD), the Fraunhofer Society , the Helmholtz Association of German Research Centers , the University Rectors' Conference (HRK), the Leibniz Association , the Max Planck Society and the Science Council started a joint initiative to improve the supply of information in research and teaching. The "Digital Information" initiative has the following priorities:

  • Guarantee of access to digital publications, digital data and sources
  • Creation of optimal conditions for the dissemination and reception of publications from German research through digital media
  • Ensuring long-term availability of digital media and content and their integration into the digital research environment
  • Support of network-based forms of scientific work through innovative information technologies

Long-term archiving

A growing proportion of the library's holdings already consists of digital information in various formats that must be preserved over the long term. Acid-free paper books can last for hundreds of years. However, materials stored digitally as a file may no longer be opened or read after a few years. Exclusive storage on digital data carriers could lead to the loss of huge amounts of data. The digital long-term archiving (DR) therefore aims to preserve digital objects for future generations. The cultural world document heritage is also increasingly being made available as digital information. For this purpose, UNESCO published the Charter for the Preservation of Digital Cultural Heritage on October 15, 2003 . The German competence network for digital long-term archiving - nestor - also advocates standards for archiving.
