internally converted into IP address.

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)

another and a person can navigate to any page by clicking on the links called ‘Hyperlinks’.

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.
