    IP Address

                      An Internet Protocol (IP) address is a unique identification number assigned to a computer connected
                      to a network. It has two main functions: host or network interface identification and location addressing.

                      IP addresses are written and displayed in human-readable notations, such as 172.16.254.1.

                           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
                      other 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.
