DISTRIBUTED AND NETWORK OPERATING SYSTEMS
This section lists distributed and network operating systems, those designed
to provide common control for a set of computers communicating through a
network. Network operating systems are considered here to be those which
provide support for networking and remote resource access, often by a separate
layer of software on top of a conventional OS. Distributed operating systems
strive for a high degree of transparency and often support data and process
Distributed systems intended primarily for real-time applications are
listed in the real-time section. Distributed systems for shared-memory
multiprocessors are listed in the multiprocessor section.

Distributed Operating Systems
Distributed operating systems differ from network operating systems in
supporting a transparent view of the entire network, in which users normally
do not distinguish local resources from remote resources.
