                  internally converted into IP address.


                  WEB PAGE
                  A single  digital  page  on the  World Wide  Web  (WWW)  that  contains  information  and links of

                  a 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 the WWW and provides several
                  services. On the other hand, a website may provide only limited services.

                  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.


                  BANDWIDTH
                  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.
