What is index.phb? What is the purpose of the index.php file?

<head>
<title>My Example Webpage</title>
<meta name="title" content="example" />
<link rel="stylesheet" href="www.example.com/css/css.css" type="text/css" />
</head>
And the same thing done the Joomla! way:
<head>
<jdoc:include type="head" />
<link rel="stylesheet" href="<?php echo $this->baseurl ?>templates/mytemplate/css/css.css" type="text/css" />
</head>
So, instead of these header parts being defined on the index.php file, the header parts are looked up from the database by bits of php code. The clever part is that both these scripts will deliver the same code to a user. If you look at the code of a joomla website, all the <?php blah /> will have been replaced by regular html code.
Good template design
index.php should be as bare-boned as you can make it because it will be re-sent every time a new page is loaded. Elements such as styling should be delivered in css files that are saved in the users cache. The tutorials here will go through the technical aspects of creating your index.php.
Why index.php ?
Index.htm has historically been the name given to the home page of a website. Thus when a user navigates to www.example.org, the webserver delivers www.example.org/index.htm. Because Joomla! is written in PHP, index.php is the automatically served file. To further complicate things, when a user navigates to the joomla website, the index.php of the root directory redirects to the index.php of the current default template.
