 Traditional offices have paper-based filing systems, which may include filing cabinets, folders, shelves, microfiche systems, and drawing cabinets, all of which require maintenance, equipment, considerable space, and are resource-intensive.In contrast, a paperless office could simply have a desk, chair, and computer (with a modest amount of local or network storage), and all of the information would be stored in digital form.Speech recognition and speech synthesis could also be used to facilitate the storage of information digitally.
