What is network operating system ?

A network operating system (NOS) is a specialized operating system that is designed to support and manage network resources such as servers, clients, and other devices within a network. It provides the necessary tools and services for communication, data sharing, security, and administration of networked devices. NOS allows multiple users to access and share resources on the network, and ensures that data is transmitted efficiently and securely between devices. Examples of network operating systems include Windows Server, Linux, and Novell NetWare.
