All spaces and things require a name so that we can have a handle for them. Perhaps there is no better name for internet space than 'cyberspace,' the name coined by science fiction novelist, William Gibson, in his 1994 novel, Neuromancer. Trying to understand what cyberspace is is difficult at the best of times. However, a good way to try and see what its components and parameters might include is to analyse what constitutes physical space.
Natural components occur naturally, without any human intervention.
In cyberspace there are no 'natural' components per se. The closest things to natural components are probably the telecommunication networks and computers that create the physical structure of cyberspace. The human is a tool-making animal and from the earliest times we have used tools to fashion the world that we live in. Communal services and structures that are provided by private citizens for free or minimal charge in the interest of the larger community. These include everything from local committees promoting tourism or employment in an area, people who help organise youth activities, people who visit old people, people who contribute to the building of a community centre, etc.
