Internet is a global system of interconnected nodes that is used to share information from one computer to another. Some important web terminologies are HTTP (Hypertext Transfer Protocol), Web Browser, World Wide Web (WWW), Web Server, URL, Web Page and Web Hosting.
HTTP is used to access or retrieve documents from WWW. Web Browser is used for retrieving, presenting and traversing information resources on WWW. WWW is used to access any document on the net with the help of HTTP and URL. Web Server delivers web pages to the browsers and other files to the applications via HTTP. URL specifies the distinct address for each resource on the Internet. Webpage is a document on WWW that has a unique URL. Web Hosting provides internet users with online computer systems for storing information, images, video, or any content accessible via the internet or web.
HyperText Markup Language (HTML) is used for creating web pages with the help of various HTML tags. The basic HTML tags are <HTML>, <HEAD>, <TITLE> and <BODY>. The two types of HTML tags are container tags and empty tags. To design a basic HTML page, type HTML code in the notepad and save it with extension .html or .htm. To save an HTML file, click on File and choose Save As. To display a Webpage, open the browser, go to File and click on Open. Now, click on Browse and select the file. The output of HTML code would be displayed in the browser.
