An operating system (OS) is a set of software that manages computer hardware resources and offers basic services to programs. The operating system, like the rest of the system software, is an essential component of a computer’s architecture.
The software that runs on an Internet Protocol (IP) network is known as a Network Operating System. It’s one of the most crucial sorts of operating system.
The NOS (Network Operating System) is a network operating system that runs on a server and allows the server to manage data, users, groups, security, applications, and other networking functions. The primary goal of the network operating system is to allow shared file and printer access across many computers in a local area network (LAN).
For example, Microsoft Windows Server 2003, Microsoft Windows Server 2008, UNIX, Linux, Mac OS X, Novell NetWare, and BSD are examples of network operating systems.
Centralized servers are extremely stable. Security is handled by the server. It’s simple to incorporate new technologies and hardware into the system. It is also possible to access servers from various places and sorts of systems remotely.
The cost of purchasing and running a server is prohibitive and dependent on a main location for most functions. It requires regular maintenance and updates are essential.
Types of network operating systems
Peer-to-peer and client/server network operating systems are the two primary varieties:
Peer-to-peer network operating systems enable users to share resources stored in a common, accessible network location. In this design, all devices are considered equal in terms of capabilities. Peer-to-peer typically performs best for small to medium LANs and is less expensive to implement.
Users in client/server network operating systems use a server to access resources. In this design, all activities and applications are gathered under one file server, allowing clients to execute individual tasks regardless of their physical location. Because the client/server model is centralized, it is more expensive to set up and necessitates significant technical upkeep.
Network operating systems have several common features.
User administration, system maintenance, and resource management features are common characteristics of network operating systems. This includes:
1. Trivial yet essential features include basic support for operating systems such as protocol and processor support, hardware detection, and multiprocessing.
2. Driverless printing and application collaboration
3. Shared file systems and databases are standard.
4. Denial of service attacks employs various methods to prevent legitimate users from accessing a system. These systems can be further protected by restricting access based on IP addresses or other distinguishing features.
5. The following are some of the most important tools in a business network: file-sharing, customer support systems, antivirus software, anti-spam services
Peer to Peer Networks is made up of a collection of computers that can share resources. Each computer in a workstation keeps track of its user accounts and security settings, so no single computer is in charge of the workgroup. Workgroups have little security and lack a central login procedure. Once a user connects to a peer on the Network, he or she has access to shared resources. There is no centralized control over sharing materials, therefore users may restrict access by removing files or folders from the network.
All printing, storage, backup, and duplication services for computers and users who connect to a network are managed by network operating systems. The networks also handle access to the Internet, local-area (LAN) and wide-area networks (WAN), port routing, and internal web services known as Intranet. Documents and files are immediately transmitted through the printing/file service filtering mechanisms of NOS. Many people may send documents or data across the network for purposes such as printing, backup, or other forms of processing.
The network operations center (NOC) manages email, also known as electronic mail, for the entire network, including users who access it remotely and over the Internet. The NOS filters out SPAM and other undesirable emails while allowing users to establish additional email addresses.
A network operating system manages the various processors, applications, and hardware devices that make up a network. The systems aid computer users in accessing the network as well as processing requests for certain documents and the use of hardware. Users also submit protocol requests to NOSs, including Transmission Control Protocol/Internet Protocol (TCP/IP) and other protocols.
