What is the World Wide Web?
The World Wide Web (WWW), most often called the Web,
is a network of computers all over the
world. All the computers in the Web can communicate with each
other by using a communication
standard called HTTP, hence you type the URL like http://www.sltnet.lk
in a browser.
How does the WWW work?
Web information is stored in documents called Web pages
which are files stored on computers
called Web servers. Computers reading the Web pages are called
Web clients that uses a program
called a Web browser to view and navigate through web pages.
The most popular browsers are
Internet Explorer and Netscape Navigator.
How does the browser fetch
the pages?
A browser fetches a Web page from a server by a standard
HTTP request containing a page
address. A page address looks like : http://www.sltnet.lk/home.htm.
How does the browser display
the pages?
All Web pages contain instructions for displaying the web
pages properly and the browser displays
the pages by reading these instructions. The most common display
instructions are called HTML
tags which look like this "<title>This is the title
of the page</title>".
Who is making the Web standards?
The Web standards are not made up by Netscape or Microsoft
but the rule-making body of the
Web, the W3C. W3C stands for the World Wide Web Consortium.
W3C puts together specifications for Web standards. The most
essential Web standards are HTML,
CSS and XML. The latest HTML standard is XHTML 1.0.
