Choosing NOS can be a complex and a difficult decision.
Every popular NOS has its strengths and weaknesses.
NOS may cost thousands of dollars depending on the
number of clients that will connect to the server. Many
networks now include more than one server type,
and knowing how to get these diverse systems to
interoperate is an important skill for a network administrator.
Operating systems on the network have their own
language. Different NOS vendors use the same terms
in different ways. For example, in a UNIX environment,
“root” refers to the master administrative account, but in
NetWare networks, it is used to identify a Novell
directory services (NDS) object. In Windows, root
can relate to the domain at the top of a Windows 2000
or XP domain tree or to the basic component of a
Distributed File System (DFS).

Linux is an operating system for computers, comparable to Windows or Mac OS
X. It was originally created by Linus Torvalds. Linux resembles UNIX, but unlike
UNIX, Linux is both Free Software and open source software. Linux runs on a
wide variety of hardware platforms, from huge mainframes to desktop PCs to
cell phones. Linux haves two parts, a kernel, which is the basic interface
between the hardware and other system software, and the functions that run on
top of it, such as a graphical user interface (GUI) and application programs. No
company sells Linux because it is an open sourced which is released to
everyone.
Windows NT is a Microsoft Windows personal computer
operating system designed for users and businesses needing
advanced capability. Windows NT has two parts, Microsoft NT
Workstation and Microsoft NT Server. The Workstation is
designed for users, especially business users, who need
faster performance and a system a little more fail-safe. The
Server is designed for business machines that need to
provide services for network-attached computers. The Server
is required, together with an Internet server such as
Microsoft's Internet Information Server (IIS), for a Windows
system that plans to serve Web pages. The NT Server is
probably the second most installed network server operating
system after Novell's NetWare operating system. Microsoft
claims that its NT servers are beginning to replace both
NetWare and the various Unix-based systems such as those
of Sun Microsystems and Hewlett-Packard. NT Server 5.0.
Essentially became what was renamed Windows 2000.
NetWare is a software product that runs
on a variety of different types of
LANs, from Ethernets to IBM token-rin
networks. It provides users and
programmers with a consistent
interface that is independent of the
actual hardware used to transmit
messages. An early - and primary
competitor was the Microsoft Window
NT operating system.
