  • Last Updated : 10 Sep, 2021

The basic definition of operating system is that the operating system is the interface between the computer hardware and user.And in daily life we use the operating system on our devices which provide the good GUI, and many more features  with it.Similarly,  network operating system(NOS) is  a  software which  connects the multiple devices and computers  on the network and allow them to share resources on the network.Let’s see what are the functions of the network of operating system.

Functions of the NOS :
Following are the main functions of NOS :

Attention reader! Don’t stop learning now. Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready.

 

  • Creating and managing user accounts on the network.
  • Controlling access of resources on network.
  • Provide communication services between the devices on the network.
  • Monitor and troubleshoot network.
  • Configuring and Managing the resources on the network.

Now let’s see type of Network Operating systems.



Types of Network operating systems :
There are main two type of network, one is peer to peer and another is client/server.Now let’s see each type one by one.

  • Peer to Peer –
    Peer to peer network operating system allow share to resources and files small sized network and having less resources.In general, peer to peer  network operating systems are used on LAN.
  • Client/server –
    Client-server network operating system provide  users access to resources through the central server.This NOS too expensive to implement and maintain.This operating system is good for the big networks which provides the many services.

Features of network operating systems :
Let’s see what are the functions of network operating system.

  • Printers and application sharing on network.
  • File systems and database sharing.
  • Provide good security by using the functionality like user authentication and access control.
  • Create backups of data.
  • Inter-networking.

Now let’s see what are the advantages of NOS.

Advantages of Network operating systems :

  • Highly stable due to central server.
  • Provide good security.
  • Upgradation of new technology and hardware can be easily implemented in network.
  • Provide remote access to server from different locations.

Disadvantages of  Network operating systems :

  • Depend on the central location to perform the operations.
  • High cost to buying server.
  • Regular updation and maintenance is required.

Now let’s see what are the examples of network operating systems.

Examples of Network Operating systems :
Following are the examples of network operating systems.

  • Microsoft Windows Server
  • UNIX/Linux
  • Artisoft’s LANtastic
  • Banyan’s VINES
