What is a Network operating System?

Unlike operation systems, such as Windows, that room designed for single users to control one computer, network operating systems (NOS) coordinate the activities of many computers throughout a network. The network operating mechanism acts as a director to keep the network running smoothly.

The two significant types the network operating equipment are:

nearly all contemporary networks space a combination of both. The networking architecture can be thought about independent of the servers and also workstations that will share it.


Peer-to-peer network operating systems enable users to share resources and files situated on your computers and to accessibility shared resources uncovered on various other computers. However, they perform not have a record server or a central management source (See fig. 1). In a peer-to-peer network, all computer systems are considered equal; they all have the exact same abilities to usage the resources easily accessible on the network. Peer-to-peer networks room designed generally for tiny to medium local area networks. Nearly all modern desktop computer operating systems, such together Macintosh OSX, Linux, and Windows, can function as peer-to-peer network operating systems.

Fig. 1. Peer-to-peer network

advantages of a peer-to-peer network:

less initial price - No need for a committed server. Setup - one operating mechanism (such as windows XP) currently in location may only should be reconfigured because that peer-to-peer operations.

disadvantages of a peer-to-peer network:

Decentralized - No central repository because that files and applications. security - go not administer the security accessible on a client/server network.


Client/server network operating systems enable the network come centralize functions and applications in one or more specialized file servers (See fig. 2). The document servers become the heart of the system, providing accessibility to resources and providing security. Separation, personal, instance workstations (clients) have access to the resources available on the file servers. The network operation system offers the device to integrate all the components of the network and enable multiple customers to simultaneously share the same sources irrespective of physical location. UNIX/Linux and the Microsoft family members of home windows Servers are examples of client/server network operating systems.


Fig. 2. Client/server network

advantages of a client/server network:

central - Resources and also data security are managed through the server. Scalability - any type of or all aspects can be changed individually as demands increase. flexibility - new technology deserve to be easily combined into system. Interoperability - All materials (client/network/server) job-related together. accessibility - Server deserve to be accessed remotely and throughout multiple platforms.

disadvantages of a client/server network:

expense - requires initial invest in dedicated server. maintain - huge networks will need a staff to ensure efficient operation. dependence - once server goes down, operations will certainly cease throughout the network.
