DNS

                  Domain Name System (DNS) is a naming system for assigning a name to the computers, services,
                  or other resources connected to the network. This name is known as domain name. For example, the
                  domain name in the www.yahoo.co.in URL is yahoo.co.in. This domain name is internally converted
                  into IP address.


                       Web page

                  A single digital page on the World Wide Web (WWW) that contains information and links of
                  another pages is called a  web page. Web pages are created by using the HyperText Markup
                  Language (HTML).

                       Website

                  A website is a collection of web pages which are interlinked to each other. A website may contain
                  thousands of web pages.


                       Web Portal
                  A website that is specifically designed to provide a single point of access for information is called web

                  portal. Web portals are also known simply as portals. The major difference between a website and a
                  web portal is that a portal works as a gateway to WWW and provides several services. On the other
                  hand, a website may provide only some limited services.

                       Hypertext

                  The text that has a special feature of connecting one web page to another is called a hypertext.

                       Link

                  A link can be defined as a web address that is used to make connectivity between web pages.

                       Hyperlink

                  A hyperlink is simply a part of the Web page that is linked to a URL. A hyperlink can appear as text,
                  an image, or a navigational tool such as a button or an arrow. When you click on a hyperlink, you will
                  jump to the URL specified by the hyperlink. Hyperlinked text usually looks different from normal text in
                  a Web page. It is often underlined, but can be formatted in a number of ways.

                  The capability of a transmission  medium  to  transmit  the maximum  amount  of data  from one
                  computer  to  another  over a  computer  network  in a  given  amount  of time  is  called  bandwidth.

                  A bandwidth is generally in bits per second (bps) or Bytes per second (Bps), Kilobytes per second
                  (Kbps) and Megabytes  per second  (Mbps). There can be  various  types  of bandwidths  which are
