The typical classroom is reaching more people on the Internet. Online programs offer convenience for non-traditional students, and companies often encourage their employees to take online classes to fit schedules. Carrie Heeter is an educator at Michigan State University who lives in California. She leads classes on the Internet, and explains the typical agenda of an online class.

Jesca Hoffman has participated in Carrie Heeter's online classes, and tells Todd about her experiences. Many students are uncertain of what to expect from the courses, since information is transferred via cyberspace.

It is difficult to keep information private in today's world of technology and widespread digital networking. The public went to work to devise cryptography to protect information people put on the Internet. Technology writer Stephen Levy explains how the U.S. Government didn't like the thought of a code they couldn't break. His book is "Crypto : How the Code Rebels Beat the Government-Saving Privacy in the Digital Age".
