As described in the article A Holistic Approach to Bit Preservation bit preservation is defined as “The required activities to ensure that the bit-streams remain intact and readable “ (E.M.Olmütz Zierau: A Holistic Approach to Bit Preservation. Thesis 2011, Hvidovre).Functional preservation builds upon the results in bit preservation, so it is important that an organisation is aware of this relationship. Bit preservation is not only about preserving the bits, but also to ensure access to the digital material over time. Bit preservation cannot stand alone, it requires also activities to ensure the understandability of the digital material over time.
