NOS, Stands for “System Working Framework” and is articulated “N-O-S.” A system working framework gives administrations to PCs associated with a system. Cases incorporate shared record get to, shared applications, and printing capacities. A NOS may either be a distributed (P2P) OS, which is introduced on every PC, or a customer server display, where one machine is the server and others have customer programming introduced.

Distributed system working frameworks incorporate heritage OSes, for example, AppleShare and Windows for Workgroups. These working frameworks offered exceptional systems administration abilities that were not accessible in early forms of Macintosh OS and Windows. They empowered PCs to perceive each other and offer documents over a link associating the machines. After some time, these systems administration highlights were coordinated into standard working frameworks, making P2P NOSes out of date.

Customer server organize working frameworks incorporate Novell NetWare and Windows Server. These NOSes give administrations from one PC to every associated machine. Novell NetWare requires particular customer programming to be introduced on all customer machines, while Windows Server works with standard Windows PCs. In the two cases, customers associate with the server and can get to records and applications in view of their entrance benefits. The focal server deals with all the associated machines and can give refreshes as expected to the customer frameworks. This makes it simple to keep every one of the PCs on the system a la mode.

While customer server NOSes were utilized for quite a few years, they too have blurred into oldness. Today, work area working frameworks have progressed organizing abilities, constraining the requirement for arrange working frameworks. Furthermore, numerous associations now utilize intranets to give online access to every neighborhood framework. Rather than requiring particular projects to be introduced

on every customer, clients can get to web applications over a nearby system or the Web.

NOTE: A system working framework may likewise allude to an essential OS that keeps running on a system gadget, for example, a switch or firewall.
