A network operating system, or NOS is a type of operating system that manages computer network resources such as data, applications and ensures security. The most common usable examples of network operating system are Microsoft Windows Server, UNIX, Linux, and Mac OS X. Here, I’ll mention some example of network operating system and types of network operating system.
What is Network Operating System?
A network operating system is a computer operating system (OS) that’s designed to create a network connection and share devices (such as printers, files) within a computer network. The network operating system has the capability to handle simultaneously multiple client requests.
The network operating system is a powerful computer, which comprises software and network protocols to communicate with other computers over a network. It’ll give you the option to remote access to another computer and it can share resources and storage within the networked computers.
The examples of network operating system are Microsoft Windows Server, UNIX, Linux, and Mac OS X, which are using to run the server programs and applications.
Simply put, network operating system is designed for connecting the multiple computers and sharing resources through a local area network (LAN).
Example of Network Operating System
The most common example of network operating system are Microsoft Windows Server, UNIX, Linux, and Mac OS X. Some other example of network operating system are Novell NetWare, Sun Solaris, AppleShare, and Berkeley Software Distribution (BSD), etc.
Microsoft Windows Server
Microsoft Windows Server is an example of network operating system which has been designed by Microsoft. Windows servers are extremely powerful and high configuration computers that’s used for enterprise-level management, data storage, applications hosting, and networking. Microsoft Windows Server ensures availability, stability, and security of a system.
The first version of Windows Server edition was Windows Server 2003. Here, I’ve listed the full releases of Windows Server as follows:
- Windows Server 2003 (April 2003)
- Windows Server 2003 R2 (December 2005)
- Windows Server 2008 (February 2008)
- Windows Server 2008 R2 (October 2009)
- Windows Server 2012 (September 2012)
- Windows Server 2012 R2 (October 2013)
- Windows Server 2016 (September 2016)
- Windows Server 2019 (October 2018)
- Windows Server 2022 (August 2021)

UNIX Operating System
This is another example of network operating system which was first developed by AT&T Corporation’s Bell Laboratories in the late 1960s. The UNIX operating system is simple, multi-tasking, multi-user, portable and stable that is used for web servers, laptops, and desktop computers.
The UNIX operating system mainly based on three parts such as the kernel, the shell and the programs. There are different version of UNIX operating system are SunOS, Solaris, SCO UNIX, AIX, HP/UX, ULTRIX, etc.

Linux Operating System
Linux is one of the most popular and open source operating system that is used in mobile phones, routers, super computers, mainframe computers, and server applications. The Linux Operating System is free and its source code is available to use.
Linux is used for all types of server applications such as web servers, database servers, DNS servers, antivirus servers, file servers, email servers, and shared servers. The important features of Linux operating system are portable, open source, multi-user, multi-programming, and it provides more security than other operating systems.
There are different distributions of Linux operating system such as Debian, Ubuntu, CentOS, Fedora, and Kali Linux Distribution.

Types of Network Operating System
Basically, there are two types of network operating systems, which are as follows:
- Peer-to-Peer Network Operating System
- Client-Server Network Operating System
A peer-to-peer network Operating System is a network system that connects multiple computers or nodes to each other and can share data with one another.
Each node of a peer-to-peer network has the same functional and operational capability. All nodes have their individual memory space to store data and resources to share with other nodes.
In peer-to-peer network Operating System, all nodes or workstations are directly connected to each other using a hub or switch. In this networking system, there no need a separate server to storage and share data or file to others.
A peer-to-peer network is used in home networks or small businesses for file sharing, direct messaging and for collaboration. The peer-to-peer network operating system examples are Torrent, Skype, Bitcoin, Limewire, and Kazaa, etc.
A client-server network Operating System is a network system that connects multiple client computers or workstations to a single server computer. The Networking Operating System is installed on the server computer and the client-server network model is controlled centrally.
In this architecture, the server computer is responsible for storage and sharing resources with the client computer. A client will make a request to server computer for accessing the resources and server computer will respond to the request in a secured way.
Here, the server is a high configuration computer that can store large amounts of data and can handle multiple client requests simultaneously.
A client-server network Operating System is used to host web application software and websites, where an application or website is hosted on a server and a client accesses the application through a network. Client-server network operating system examples include web server, file server, print server, DNS server, database server, and mail server.
Functionalities of Network Operating System
A network operating system is a system that is designed for managing the network resources, creating network connections, and sharing the file among multiple computers within the network.
The major functionalities of Network Operating System are as follows:
- Storage the data on system and controlling the file access.
- Sharing of resources such as file, application, and printer.
- Improved performance and ensure system security.
- Protect data from cyber threat such as virus and malware.
- Provides remote access to server and applications.
- Manage the operations between main memory and hard disk.
- Creating a new user, user group and managing the accounts on the network.
- Receive the client request and process the request.
- Monitor the system and troubleshoot the network.
- Managing the resources on the network.
- Ensure system security by blocking unauthorized access.
Services of Network Operating System
There are different services provided by a network operating system. The most common services are listed as follows:
- DHCP (Dynamic Host Configuration protocol) services
- DNS (Domain Name System) services
- Email services
- Web services
- File and print services
- Peripheral Sharing Service
- Communication Service
