Itm 301 introduction to network operating systems. 6. 1 characteristics of a network operating system. 6. 4 determining software requirements a linux nos. Network operating systems (noss) distribute their functions over a number of networked computers. It then adds functions that allow access to shared resources by a number of users concurrently. Nos computers take on specialized roles to accomplish concurrent access to shared resources. Client systems contain specialized software that allows them to request shared resources that are controlled by server systems responding to a client request. The nos enhances the reach of the client pc by making remote services available as extensions of the local native operating system. Although a number of users may have accounts on a pc, only a single account is active on the system at any given time. Nos supports multiple user accounts at the same time and enables concurrent access to shared resources by multiple clients. A nos server is a multitasking system.
