<h2>What is the WWW?</h2>

<ul>
  <li>WWW stands for the <b>World Wide Web</b> </li>
	<li>The World Wide Web is most often called <b>the Web</b></li>
  <li>The Web is a network of computers <b> all over the world</b></li>
  <li>All the computers in the Web can <b>communicate with each other</b></li>
  <li>All the computers use a <b>communication standard called HTTP</b></li>
</ul>

<hr />

<h2>How Does the&nbsp; WWW Work?</h2>
<ul>
  <li>Web information is stored in documents called <b>Web pages</b></li>
  <li>Web pages are files stored on computers called <b>Web servers</b></li>
  <li>Computers reading the Web pages are called <b>Web clients</b></li>
  <li>Web clients view the pages with a program called a <b>Web browser</b></li>
  <li>Popular browsers are <b>Internet Explorer and Mozilla Firefox</b></li>
</ul>
<hr />
<h2>How Does the Browser Fetch the Pages?</h2>
<ul>
  <li>A browser fetches a Web page from a server <b>by a request</b></li>
  <li>A request is a standard HTTP request containing <b>a page address</b></li>
  <li>A page address looks like: <b>http://www.someone.com/page.htm</b></li>
</ul>
<hr />
<h2>How Does the Browser Display the Pages?</h2>
<ul>
  <li>All Web pages contain instructions on <b>how to be displayed</b></li>
  <li>The browser displays the page by <b>reading these instructions</b></li>
  <li>The most common display instructions are called <b>HTML tags</b></li>
  <li>The HTML tag for a paragraph looks like this: <b>&lt;/p&gt;</b></li>
	<li>A paragraph in HTML is defined like this <b>&lt;p&gt;</b>This is a Paragraph<b>&lt;/p&gt;</b></li>
</ul>
<hr />
<h2>Who is Making the Web Standards?</h2>
<ul>
  <li>The Web standards are <b> not made up</b> by Netscape or Microsoft</li>
  <li>The rule-making body of the Web is the <b>W3C</b></li>
  <li>W3C stands for the <b> World Wide Web Consortium</b></li>
  <li>W3C puts together specifications for <b> Web standards</b></li>
  <li>The most essential Web standards are <b> HTML, CSS and XML</b></li>
  <li>The latest HTML standard is <b> XHTML 1.0</b></li>
</ul>
