It provides the availability (continuity of the services) rather than faults. It dynamically allocates processes to the random CPU and the files storage is also managed by the operating system which means that the user would not know which hardware has been used for the processing of its computation and for storing its file.Īs it is mentioned above the distributed operating system allows resource sharing in which an application can use resources located in any computer system. The distributed operating system is less autonomous than network operating system as the system has complete control in this environment. The main aim of the distributed operating system is the transparency where the use of multiple hardware resources is hidden from the users. This is achieved by enabling the proper communication between the different computers connected with each other.

The distributed operating system handles a group of independent computers and makes them look like an ordinary centralised operating system. Definition of Distributed operating system There is no provision of fault tolerance in the network operating system. A network operating system cannot control the utilisation of resources which causes the improper distribution of the resources. In some implementations, there is a remote login for the remote operating systems to access the resources. The local operating system residing in each particular computer preserves its identity which is visible to users too and behaves as a solitary operating system. Unlike the distributed operating system, the network operating system does not work in a collaborated way. On the other way, if the process request for the local resource, the network OS layer sends the request to the local OS kernel. When the process demand for the non-local resources, the network OS layer communicates to the network OS layer of the node that contains the resource and employs the access to the resource by using it. Essentially the processes interact with the network OS layer instead of the kernel of the local operating system. Here the network OS layer present between the kernel of the local OS and user processes. The functioning of the network operating system can be explained by the diagram depicted below. The idea behind the network operating system is to permit resource sharing among two or more computers operating under their own OSs. It is considered as the primary form of an operating system for the distributed architecture.
Remote processing operating system software#
The network operating system is the platform to run a system software on a server and allow the server to manage the users, data, groups, security, applications and other networking functions.
