  We need much better understanding of information processing and computation
as its primary form. Future progress of new computational devices capable of
dealing with problems of big data, internet of things, semantic web, cognitive
robotics and neuroinformatics depends on the adequate models of computation. In
this article we first present the current state of the art through
systematization of existing models and mechanisms, and outline basic structural
framework of computation. We argue that defining computation as information
processing, and given that there is no information without (physical)
representation, the dynamics of information on the fundamental level is
physical/ intrinsic/ natural computation. As a special case, intrinsic
computation is used for designed computation in computing machinery. Intrinsic
natural computation occurs on variety of levels of physical processes,
containing the levels of computation of living organisms (including highly
intelligent animals) as well as designed computational devices. The present
article offers a typology of current models of computation and indicates future
paths for the advancement of the field; both by the development of new
computational models and by learning from nature how to better compute using
different mechanisms of intrinsic computation.
