Sarah took a class in Microsoft Word 2010 and she found it confusing. Leo says that Microsoft didn't want people "burrowing" and so they created a ribbon user interface to help people do more with a click. The guy who created the Word Ribbon is also responsible for the look of Windows 8, the most hated OS ever.
Sarah thinks her classroom teacher was going into her computer via the network and messing with her results. Can she do that? Leo says it is possible to remotely alter the screen. It's called Remote Access. And a teacher can do it if the technology they're using is sophisticated enough. That's why Leo recommends some students learn from a book.
