What is a network operating system and what are its functions?

What is a network operating system and what are its functions? is profiled by BTW Media because published evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• Network operating system (NOS) is a computer operating system (OS), mainly used to support workstations, PCS.
• The software behind NOS enables multiple devices in a network to communicate with each other and share resources.

Network operating system (NOS) coordinates the activities of multiple computers on a network. This can include devices such as PCS, printers, file servers, and databases that are connected to the local network. The role of NOS is to provide basic network services and features that support multiple input requests simultaneously in a multi-user environment.

What is a network operating system

A network operating system (NOS) is a computer operating system (OS) primarily used to support workstations, PCS, and in some cases, older terminals connected to a local area network (LAN). The software behind NOS enables multiple devices in a network to communicate with each other and share resources. However, typical NOS no longer exists because most operating systems have a built-in networking stack that supports the client-server model.

Advantages and disadvantages of network operating system

Thanks to his central server, he’s highly stable. It also provides good security, and new technologies and hardware upgrades can be easily implemented in the network. It provides remote access to servers in different locations.

However, network operating systems rely on a central location to perform operations. The cost of buying its servers is high, and it requires regular updates and maintenance.

Functions of network operating system

Network operating systems are designed to manage and coordinate the activities of a network, ensuring smooth communication and data sharing between devices. Here are some of the key functionalities typically provided by a network operating system.

1. User account management: Create, modify, and delete user accounts across the network, setting user permissions and access controls.

2. Access control: Regulate what resources users can access, ensuring that sensitive data is protected and users are only able to access the network resources necessary for their work.

3. Communication services: Facilitate communication between devices on the network, including the routing of data packets and the establishment of connections.

4. Network monitoring: Continuously monitor the network to ensure it is running smoothly, checking for any issues that may arise and addressing them promptly.

5. Troubleshooting: Diagnose and resolve network faults, using various tools to identify the source of problems and implement solutions.

6. Configuration management: Set up and adjust network configurations, such as IP addressing, DNS settings, and DHCP scopes, to meet the needs of the organisation.

Examples of network operating systems

True network operating systems are classified as software that enhances the functionality of the operating system by providing additional network features. Here are examples of current network operating systems and their vendors.

1. Microsoft windows server: This is the most widely used NOS designed by Microsoft. Known for its power, availability, stability, and high security, Windows servers are designed for enterprise-class management, data storage, networking, and application hosting.

2. Unix operating system: The Unix operating system was originally developed by AT&T’s Bell LABS in the late 1960s. It is a portable, stable, multi-user and multi-tasking system commonly used in web servers, desktop computers and laptops. The Unix operating system consists of three main parts, the kernel, the shell, and the program.

3. Cisco internet OS (IOS): Cisco IOS is a family of proprietary network operating systems used by both service providers and enterprises. Several models of routers and network switches made by Cisco systems include IOS. It provides a complete package routing, switching, Internet and telecommunication functions integrated into a single multitasking operating system.

In addition, some multipurpose operating systems, such as OpenVMS, come with features that enable them to be described as network operating systems.
