HTML - Hyper Text Markup Language
Now that everyone has had some practice writing HTML, we'll talk a little more about it.
It's a tag based language. There is an opening tag, a closing tag, and everything inside of those tags are part of it. Tags can have attributes, which describe a little more about the tag.
<html>
<head></head>
<body>
<a href="nextpage.html"> This is what the link says </a>
</body>
</html>
You can see the tags are paired. the href="" is an attibute of the <a> tag. The <a> tag is a link. The attribute tells it where to link to.
Tables are used to lay out content, just like in Word
<table>
<tr>
<td> this is the first cell, first row </td>
<td> this is the second cell, first row </td>
</tr>
<tr>
<td> this is the first cell, second row </td>
<td> this is the second cell, second row </td>
</tr>
</table>
XML - eXtensible Markup Language
XML is also a tag based language. Where HTML has set tags you can use, in XML you make up your own tags. It is used in business to transfer data between different progams such as between a website and a database.
