Network Operating system / Internet and Network

Now that have a general idea of the network topologies,  cable types,  and network architecture, let's look at the network operating system (NOS).  We focus on the three most widely used network operating systems today :

• Windows 2000 Server and Windows Server 2003/2008
• Novell NetWare 
• UNIX

             Once you have connected the cables to the hubs and 5he clients to the cables,  it is time to install a network operating system.  The network operating system is responsible for providing services to clients on the network.  These services could be the sharing of files or printers; the serve4 could be providing name resolution through DNS services or logon services by being a directory server.
      Let's take a look at some of the popular network operating systems that provide network services to their clients.  For this discussion,  any time that we mention Windows 2000 or Windows Server 2003,  we can also include Windows NT Server,  because Windows 2000 and Windows Server 2003 werenbuits off Windows NT technologies and are the successors to Windows NT.
