This is an operating system that has the capabilities of supporting information and resources sharing between network computers. It provides an influence between workstation in a network.
Network Operating System Services includes:
File and resource sharing – Is the fundamental requirement for a network ie is the reason behind networking computers.
Configurability and usability – configuration and use should be easy paper documentation, electronic format, books should be provided for a first time user to get the network up and running.
Support – any kind of useful information should always be available.
Types of Network Operating System:
• It is the first NOS to support the multiple platforms
• It was the first NOS to support multiple and varying topologies and routines between this different topologies
• Novel Netware servers typically outperform other network servers because it is by design network operating system
Features of Novel NOS include:
• Novel directory services (NOS)
NDS offering is what makes a novel a strong competitor of Windows NT. It uses X.500 standard and therefore prevent the creation of duplicate objects. Each object has a distinguish name (DN). Because NDS directory services is displayed in neat graphically arranged order, objects such as users, printers, workstations and application servers are sharing an organization structure to the system administration user. You can log in as the administrator user from any workstation. This enables you to manage the entire directory tree. You can add and remove user's services and other network resources. Users need to log only once in order to gain access to all network resources.
• Security Services
All passwords flows back and forth from the Netware server to the client workstation in an encrypted format, even the administrator can not look at user's password on the server. The administrator can remove and add users permission but only the users know their own password, even if users get to physical Netware server, they have no greater access to resources that would have on their own workstation is build into the network system because Netware security is build into the Netware system of the lowest level. All attempts to access information or resources on the network go through on the network security system.
• Database services
Provide a central repository for information on the server, the major database management system available is
Netware C – a database record management system index with a database key for easy development for vertical application.
Netware SQL – standard used for accessing records stored in relational database system.
Oracle DBMS – it is SQL based system used primarily business critical application in different lines of business.
• Messaging services
Provide a messaging service called Netware message handling service. This provides ease of message, transmission between many fronted applications. This application can share data over the LANs and Novel word.
• Print services
Allows up to 16 printers to be shared per print server on the Network and therefore a real flexibility of printing, Printers need not to be attached to the actual print server in order to be operated.
• Netware loadable machine (NLM)
Netware loadable modules are maintained by Novel Netware operation. It provide the power needed to support hierarchy used network services in the server. have the same access to the Netware security services making them same to control and monitor.
Advantages of the Novel Netware
Has the print and file server software in the business and its sharing of files and printers that makes a network important and useful. Has the best LAN NOS directory service.
As an application server its failures as Windows NT beats it on this case. Poor at printing data / information network status and management. It has build in network management tools that are not powerful.
