" Records management practices have established life-cycle management for many years, for both paper and electronic records. The major implications for life-cycle management of digital resources, whatever their form or function, is the need actively to manage the resource at each stage of its life-cycle and to recognise the inter-dependencies between each stage and commence preservation activities as early as practicable. This represents a major difference with most traditional preservation, where management is largely passive until detailed conservation work is required, typically, many years after creation and rarely, if ever, involving the creator. There is an active and inter-linked life-cycle to digital resources which has prompted many to promote the term ""continuum"" to distinguish it from the more traditional and linear flow of the life-cycle for traditional analogue materials. We have used the term life-cycle to apply to this pro-active concept of preservation management for digital materials.";; Definition by https://www.dpconline.org/handbook/glossary

Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data. By contrast, lossy compression permits reconstruction only of an approximation of the original data, though usually with improved compression rates.
