Explain Network operating system?

A Network Operating System (NOS) is an operating system designed specifically to manage and coordinate network resources, devices, and services. It is responsible for providing a common platform for communication and resource sharing between different computers and devices in a network.

A NOS typically includes features such as network protocols, file and print services, security, and management tools. It enables multiple users to access and share resources such as files, printers, databases, and applications across the network.

A NOS can be classified into two main categories:

  1. Client-server
  2. Peer-to-peer

In a client-server model, a centralized server manages and controls the network resources and services, while client computers access these resources and services through the server. Examples of client-server NOS include Microsoft Windows Server, Linux-based servers, and Novell Netware.

In a peer-to-peer model, each computer on the network has equal privileges and responsibilities, and resources and services are shared directly between them without the need for a central server. Examples of peer-to-peer NOS include Windows Peer-to-Peer Networking and Apple Bonjour.

Some common features of a NOS include:

  1. Network protocols for communication between computers and devices
  2. File and print services for sharing files and printers
  3. User authentication and access control for securing the network
  4. Remote access and administration for managing the network from a remote location
  5. Network monitoring and troubleshooting tools for detecting and resolving network issues.
