Basic WWW concepts

World Wide Web which is sometimes called as w3 or Web is the most popular and powerful application on the Internet. It was originally created to build the infrastructure for sharing documents on the Internet.

Since different types of computers will access these documents, it was decided to have a standard structure for them. This standard was called HTML (HyperText Markup Language).

Today the web is a huge collection of documents stored on computers around the world.


First developed by Tim Berners-Lee in 1990, HTML is short for Hypertext Markup Language. HTML is used to create electronic documents (called pages) that are displayed on the World Wide Web. Each page contains a series of connections to other pages called hyperlinks. Every web page you see on the Internet is written using one version of HTML code or another.

Web page

A web page or webpage is a document commonly written in HTML(Hypertext Markup Language) that is accessible through the Internet or other networks using an Internet browser. A web page is accessed by entering a URL address and may contain text, graphics, and hyperlinks to other web pages and files. The page you are reading now is an example of a web page.


A site or website is a central location of various web pages that are all related and can be accessed by visiting the home page of the website using a browser. For example, the eAcademy website address URL (Uniform Resource Locator) is From our home page, you could get access to any of the web pages (like this one) contained on our website.


The homepage or home page is the name of the main page of a website where visitors can find hyperlinks to other pages on the site. By default, the homepage on all web servers is index.html, however, can also be index.htm, index.php, or whatever the developer decides.


Also known as a web address, a URL (Uniform Resource Locator) is a form of URI and a standardized naming convention for addressing documents accessible over the Internet and Intranet. An example of a URL is, which is the URL for the eAcademy website.


Alternatively referred to as a link and web link, a hyperlink is an icon, graphic, or text in a document that links to another file or object. The World Wide Web is comprised of hyperlinks linking trillions of pages and files to one another.


Short for Hypertext Transfer Protocol, HTTP is a set of standards that allow users of the World Wide Web to exchange information found on web pages. When accessing any web page entering http:// in front of the address tells the browser to communicate over HTTP. For example, the URL for Computer Hope is Today's browsers no longer require HTTP in front of the URL since it is the default method of communication.


This is the hardware and software that allows one computer to connect to another computer. A server is a program that knows a language or protocol for communication.
