  The work attempts to unify the conceptual model of the user's virtual
computer environment, with the aim of combining the local environments of
operating systems and the global Internet environment into a single virtual
environment built on general principles. To solve this problem, it is proposed
to unify the conceptual basis of these environments. The existing conceptual
basis of operating systems, built on the "desktop" metaphor, contains redundant
concepts associated with computer architecture. The use of the spatial
conceptual basis "object - place" with the concepts of "domain", "site", and
"data object" allows to completely virtualize the user environment, separating
it from the hardware concepts. The virtual concept "domain" is becoming a
universal way of structuring the user's space. The introduction of this concept
to describe the environments of operating systems provides at the mental level
the integration of the structures of the local and global space. The use of the
concept of "personal domain" will allow replacing the concept of "personal
computer" in the mind of the user. The virtual concept of "site" as an
environment for activities and data storage will allow abandoning such concepts
as "application" (program), or "memory device". The site in the mind of the
user is a virtual environment that includes both places for storing data
objects and places for working with them. The introduction of the concept
"site" into the structure of operating systems environments and the concept of
"data site" into the structure of the global network integrates the structure
of the global and local space in the user's mind. The introduction of the
concept of "portal" as a means of integrating information necessary for
interaction, allows ensuring the methodological homogeneity of the user's work
in a single virtual environment.
