It is quite easy to implement
both web servers and browsers. In fact, today computer science students often write a simple web server as
a programming exercise.
Another reason for the success of the WWW is that Tim Berners-Lee and the others made all their code
freely available to all. They encouraged the participation of academic and commercial parties, and the resulting
collaboration brought millions of people to the WWW.
The related technology of the hypertext markup language (HTML) also allows people with limited technical
understanding to format information to be made available over a web server. HTML is a text formatting
language that browser programs understand. To ready a file for presentation as a web page, the author ???marks
up??? the text with HTML ???tags??? which tell the browser how to present the information.
Many students today, from all disciplines, create their own web pages, having learned enough HTML on
their own to do an adequate job, or having purchased an inexpensive program to help them do it. There are many
books and web pages available to help web authors learn HTML, so we will not provide a full tutorial here.
However we will show an example web page that demonstrates the general use and form of HTML.
