Network Operating System (NOS) is a specialized type of operating system designed to manage and control network resources. It provides the foundation for network communication and resource sharing among multiple computers connected to a network.
Key functions of a NOS include:
- File sharing: Allows users on different computers to access and share files across the network.
- Print sharing: Enables multiple users to share printers connected to the network.
- Application sharing: Provides access to applications installed on a central server to multiple users.
- Security: Implements security measures to protect the network and its resources from unauthorized access.
- Network management: Manages network devices, monitors network traffic, and diagnoses network problems.
Examples of NOS:
- Windows Server: Microsoft’s server operating system, offering various features for network management and resource sharing.
- Linux Server: A family of open-source server operating systems, including Ubuntu Server and Red Hat Enterprise Linux, providing robust network capabilities.
- macOS Server: Apple’s server operating system, designed for managing Apple devices and services within a network.
In essence, a NOS acts as the central nervous system of a network, coordinating the communication and resource sharing between different devices.
