A Network Operating System is an operating system that includes special functions for connecting computers and devices into a network. The term network operating system, however, is generally reserved for software that enhances a basic operating system by adding networking features. Network operating system implements protocol stacks as well as device drivers for networking hardware. This paper will identify the Domain Name Server (DNS), Web Server, Windows Internet Naming Service (WINS), and the Cisco Internetwork Operating System (IOS).

DNS is a database system that translates a fully qualified domain name into an IP address. If a DNS does not know how to translate a particular domain name it will asks another DNS until the correct IP address is returned.
Web ServerA web server is a computer that delivers Web pages. Every Web server has an IP address and possibly a domain name. For example, if you enter the URL http://www.yahoo.com in your browser, this sends a request to the server whose domain name is yahoo.com/mail.html.
