This is an operating system that has the ability to support the exchange of information and resources between computers on the network. It provides an influence between workstations on a network.

Network operating system services include:

Sharing of files and resources: It is the fundamental requirement for a network, that is, it is the reason behind networked computers.

Configurability and ease of use: the configuration and use must be easy paper documents, electronic format, books must be provided for a first time user for the network to be up and running.

Support: any kind of useful information should always be available.

Types of network operating system:

network novel

• It is the first NOS to support multiple platforms

• It was the first NOS to support multiple and varied topologies and paths between these different topologies.

• New Netware servers generally outperform other network servers because it is a network operating system by design.

Features of Novel NOS include:

• New directory services (NOS)

The NDS offering is what makes a novel a strong competitor to Windows NT. It uses the X.500 standard and therefore prevents the creation of duplicate objects. Each object has a distinguished name (DN). Because NDS directory services are displayed in a neat graphical order, objects such as users, printers, workstations, and application servers share an organized structure with the system administrator user. You can log in as an administrator user from any workstation. This allows you to manage the entire directory tree. You can add and remove user services and other network resources. Users need to log in only once to gain access to all network resources.

•Security services

All passwords flow back and forth from the Netware server to the client workstation in an encrypted format, even the administrator cannot see the user’s password on the server. The administrator can remove and add user permissions, but only the users know their own password, even if the users access the physical Netware server, they do not have greater access to resources than they would on their own workstation integrated into the Netware system. network because Netware security is built into the Netware system at the lowest level. All attempts to access information or resources on the network go through the network’s security system.

• Database services

To provide a central repository for information on the server, the main database management system available is

Netware C: A database record management system index with a database key to facilitate vertical application development.

Netware SQL: Standard used to access records stored in a relational database system.

Oracle DBMS: It is an SQL-based system used primarily by business-critical applications in different lines of business.

• Courier services

Provide a messaging service called Netware Message Handling Service. This provides ease of messaging between many front-end applications. This app can share data via LAN and Novel word.

• Printing services

It enables sharing of up to 16 printers per print server on the network and therefore true printing flexibility. Printers do not need to be connected to the actual print server to work.

• Netware Loadable Machine (NLM)

Netware loadable modules are maintained by the Novel Netware operation. It provides the necessary power to support the hierarchy of network services used in the server. they have the same access to Netware security services making them equal to control and monitor.

Advantages of Novel Netware

You have the file and print server software in the business and the file and printer sharing that makes a network important and useful. It has the best LAN NOS directory service.

Disadvantages

As an application server it fails, since Windows NT beats it in this case. Poor in status printing and data/information network management. It has built-in network management tools that are not powerful.
