As a geographer I must put my oar into this pond. On of the more pervasive meanings of space is *context*, for example cultural. In the experienced world our reality is a set of superimposed spaces: academe, queer space, the dark nation, kid space, etc. As we move about the physical world we may have no knowledge of how important a place is in different spaces. Cyberspace is the physical world seen through the eyes of those who communicate on the internet. Cyberspace has holes in it: places not served by the internet. Cyberspace has regions served by Wi-Fi networks. Cyberspace has places or nodes where communication channels converge. Mapping is another term that is related to space. One speaks of a mapping of one phenomenon over the space of another. The space may be physical or conceptual. Martin Dodge has been the leader in defining the geographies of cyberspace.
