					Network Operating System



A network operating system is software that controls a network of
computer and its message traffic and queues. It controls access by
multiple users to network resources such as files and provides for
certain administrative functions including security of the system. A
network operating system is not the same as the networking tools provided
by some existing operating systems such as Windows XP. A network
operating system is one that has been specifically written to keep
networks running at optimal performance.

A network operating system is most frequently used with local area
networks and wide area networks, but it can also have applications for
larger network systems. A network is a series of multiple computers
connected to a central server and is most often used in businesses for
the purpose of file sharing.

The network operating system is one that includes special functions for
connecting computers and devices into a local area network. Some popular
systems for both DOS and Windows systems include Novell Netware, Windows
NT and 2000, Sun Solaris, and IBM OS/2. A network operating system has
many features that are essential to file sharing. They include:

* Providing basic operating system features like support for processors,
protocols, automatic hardware detection and support for multi-processing
of applications
* Security features such as authentication, authorization, log-on
restrictions and access control
* Providing name and directory services
* Allowing file, print, web services, back-up and replication services
* Support for inter-networking such as routing and WAN ports
* Give user management and support tools for log on and log off, remote
access, system management, administration, and auditing tools with
graphical interfaces
* Clustering capabilities, fault tolerant, and high availability systems

Many network operating systems are familiar to individual computer users
in that they are often network versions of personal computer operating
system. That includes Windows 2000 Professional, Windows NT, and Red Hat
Linux.

When you have a series of computers all hooked together on a network, the
operating system used to control those computers is very important. All
effective network operating systems should have built-in measures of
security that keep the computers on the network safe from breach by
outsiders. Monitoring capabilities by a system administrator is also
very important to have in a network operating system.

Many businesses, both large and small take great pains in choosing the
right type of operating system for their network. They want to make sure
that sensitive information is not compromised in any way. That’s why
choosing a network operating system needs to be everything that the
company needs it to be.
