DNS

                  Domain Name System (DNS) is a naming system for assigning names to the computers, services, or
                  other resources connected to the network. These names are known as domain names. 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.

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

                  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 the 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 elements such as a button or an arrow. When you click on a hyperlink, you
                  will be taken 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 expressed 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
