    Internet-based companies called search engines use complex programs to keep track of the changing information available on the Internet, and they will gather sites you're after and let you peruse them.

    Generally, text editors DO NOT have formatting functions.
    If they do, some formatting may not be saved when saving as .txt or .html.
    Ex. Notepad, Wordpad
    Notepad will be the text editor used in lab to create and edit your webpage!
    The 2 steps you should take to see changes to your webpage in Internet Explorer:
    Save changes in Notepad
    Reload the web browser

    Ex. Wow, <i>that</i> is interesting
