IP Address

                  An Internet Protocol (IP) address is an 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 Web page is a document of information that can be accessed and viewed through a web
                  browser. A web page is generally contained in a website and constitutes as a source of information
                  that floats in the world wide web. The information is usually coded in HTML (Hypertext Markup
                  Language). Web page may be retrieved from a local host computer or from a remote computer
                  with the help of Internet. Web pages are requested and served from web server using protocols
                  like-Hyper Text Transfer Protocol (HTTP).

                  Web pages may consist of static pages (which are stored within a file system of a web server)
                  and/or dynamic pages (which contain files of run-time nature i.e., which facilitates online data
                  transformation). Web pages may contain information in the form of text, images, pictures, sound,
                  audio, video, etc.
                  Website

                  A location on the web server where an individual or any organisation uploads its information is
                  known as website. A website is a collection of one or more web pages which display information
                  with the help of a web browser. A website can be compared to a book which contains different
                  chapters in the form of web pages.

                  The first page of a website is known as ‘Home Page’. The pages on a website are linked to one
                  another and a person can navigate to any page by clicking on the links called ‘Hyperlinks’.
                  Websites are hosted on the web server on rental basis by the ‘Internet Service Providers’ (ISP). In
                  order to access them, every website is provided with a unique name. The websites may be owned
                  by individuals, agencies, companies, colleges, universities, government bodies, etc.
                  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 provides only some limited services.
                  Hypertext

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