Even when you're not thinking about it, nearly everything you do is influenced by math, science and technology. In fact, just by looking at this webpage you are using one of the fastest-growing technologies there is – the Internet!
The Internet is a global network made up of millions of separate computers, connected to one another through servers. These computer severs have a lot more storage space than your own computer and they collect and store information. Many computers speak to each other through the Internet. Once you are on-line, you have a lot of options, just like going to a shopping mall.
A webpage, like the one you're on now, is programmed using different computer languages. One popular language is called HTML. HTML stands for HYPER TEXT MARKUP LANGUAGE. |

<td><img src="images/spacer.gif" width="1" height="20" border="0" alt=""></td>
</tr>

JavaScript is another "behind the screen" language that can allow you to interact with the Web page. Some tricks using JavaScript: |
