The World Wide Web
Article ID: KB101438
The
World Wide Web (or "WWW" or "the Web") is a network of computers all over the
world. These computers can communicate with each other using a method called
"Hyper Text Transfer Protocol," or "HTTP."
Any
web page, image, music, or file that you access on the web is stored on a
special type of computer called a "web server." A computer (like the one you are
using now) connected to the internet can request to view the page from a server.
These computers are called "web clients." They view the pages with a program
called a "web browser."
Some examples of web browsers are Internet Explorer, Netscape, or Opera.
Each web page contains instructions on how to display it. Most web pages use
an instruction "language" called "HTML" (Hyper Text Markup Language). This
language was created and is updated by the
World Wide Web Consortium
(W3C). The W3C puts together specifications of how the language works. Each
browser reads the instructions a little differently, which explains why a web
page may look one way in Internet Explorer and another way in Netscape. There
are other types of specifications like CSS (Cascading Style Sheets) and XML (eXtensible
Markup Language).
These tutorials will concentrate on HTML and CSS. In the next article, you'll
find out more about what HTML is.
