The term has also been used by Luciano Floridi, on the basis of biosphere, to denote the whole informational environment constituted by all informational entities (thus including informational agents as well), their properties, interactions, processes and mutual relations.[3] It is an environment comparable to, but different from cyberspace (which is only one of its sub-regions, as it were), since it also includes off-line and analogue spaces of information. According to Floridi, it is possible to equate the Infosphere to the totality of Being. This equation leads him to an informational ontology.
