Hye friends.
Learning Networking is a really a big deal.
I am following this link for learing the link. My presentation is abstract from this link. For the reason of technicality in language I am giving the link that I used for my presentation "Top 3 Network OPERATING system"

"http://compnetworking.about.com/cs/networknos/"

Enjoy networking

Popular network operating systems include Windows, Mac, Linux, NetWare, and OS/2. Learn about computer networking from the operating system point of view.
NOS - A Definition
The term "NOS" stands for network operating system. A NOS contains protocol stacks as well as device drivers for network hardware... .
Windows Networking
Essential networking topics for the Microsoft Windows family of operating systems such as dial-up networking, remote access, and connection sharing.

Which NOS is Right for You?
Which network operating system is the "best" one? This article provides the resource information you need to make an informed decision, including links to discussions amongst the experts on our message board.

NOS - Network Operating System
Definition: A NOS is a network operating system. A network operating system implements protocol stacks as well as device drivers for networking hardware. Some network operating systems, like Windows 98 Second Edition, also add custom networking features like Internet Connection Sharing (ICS).
Network operating systems have existed for more than thirty years. The UNIX® operating system was designed from the beginning to support networking. In its early forms, Windows did not support networking, so Novell NetWare became the first popular network operating system for the personal computer (Windows 95 and Windows for Workgroups were Microsoft's first network operating system products). Today, nearly any consumer operating system qualifies as a NOS due to the popularity of the Internet and the obvious need to support Internet Protocol (IP) networking at a minimum.
We can use these OPERATING SYSTEM in Two ways
As a workstation(client)
As a Server
So the networking is divided into two parts

Peer to Peer networking

Client Server NETWORKING
Peer to Peer networking: Different workstations are connected to each other for exchange of information, resource sharing. Yes, It is possible to share the resources of other computer in the networking. Moreover, we can also share the internet from one computer only. But we can not assign permissions or add restriction on computer in peer to peer networking
Pro:
1. Resources are shared
2. Cost is minimized
3. Information at one place
OPERATING SYSTEM used:
1. Windows 95
2. Windows 98
3. Windows ME
4. Windows 2000(home edition , professional)
5. Windows XP
6. Windows Vista
7. Windows 7

Client Server NETWORKING
In Client Server Networking, there is a relationship like Father-Child between the computers. One computer plays the role of Father (Server) and other computer plays the role of children (clients)
Server is the one who process the queries of the which are input by the clients. It performs all the task as mentioned in peer to peer networking along with it provided the restriction and policies for clients.






Server Types
Application Servers
Sometimes referred to as a type of middleware, application servers occupy a large chunk of computing territory between database servers and the end user, and they often connect the two.
Audio/Video Servers
Audio/Video servers bring multimedia capabilities to Web sites by enabling them to broadcast streaming multimedia content.

Chat Servers
Chat servers enable a large number of users to exchange information in an environment similar to Internet newsgroups that offer real-time discussion capabilities.
FTP Servers
One of the oldest of the Internet services, File Transfer Protocol makes it possible to move one or more files securely between computers while providing file security and organization as well as transfer control.
List Servers
List servers offer a way to better manage mailing lists, whether they be interactive discussions open to the public or one-way lists that deliver announcements, newsletters, or advertising.
Mail Servers
Almost as ubiquitous and crucial as Web servers, mail servers move and store mail over corporate networks (via LANs and WANs) and across the Internet.
News Servers
News servers act as a distribution and delivery source for the thousands of public news groups currently accessible over the USENET news network.

Proxy Servers
Proxy servers sit between a client program (typically a Web browser) and an external server (typically another server on the Web) to filter requests, improve performance, and share connections.
Telnet Servers
A Telnet server enables users to log on to a host computer and perform tasks as if they're working on the remote computer itself.
Web Servers
At its core, a Web server serves static content to a Web browser by loading a file from a disk and serving it across the network to a user's Web browser. This entire exchange is mediated by the browser and server talking to each other using HTTP. Also read ServerWatch's Web Server Basics article.
