                      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 contains
                      thousands of web pages.

                      WEB PORTAL

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

                      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.

                      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.
