Business Technology classes give you opportunities to learn about a lot of software that could be used not just for business but also for art. You can find out how to use Microsoft Word to it's fullest extent almost, and learn a great deal of HTML that could be used to build websites for personal reasons instead of for a business.
You also learn about:
Voice Recognition, and other input devices
How to set up a data base with Microsoft Access
How to type Memos, Business Letters, Personal Letters, and almost everything in between
You also get to learn how to balance a webpage to give your site a professional look to it
As an aspiring author I've found these courses ideal for learning more about the word processor I use, and how to actually create a website (like this one)
