The use of the Internet, particularly the World Wide Web, as the major medium of communication distinguishes online teaching. As a result, you don't need to be somewhere to teach when you teach online. You won't have to drag your briefcase of papers or your laptop into a classroom, stand at a lectern, scrawl on a whiteboard, or mark papers in a stuffy room while your pupils take a test. You don't even have to wait for students to show up for conferences in your office. You can have “office hours” on weekends or at night after dinner.

All of this is possible whether you live in a little town in Wyoming or a large city like Bangkok, and even if you work for a college with administrative headquarters in Florida or Dubai. You can attend an important conference in Hawaii on the same day that you teach your class in New Jersey, using your laptop to connect to the internet via a local cafe's wireless hotspot or your hotel room's high-speed network.

Students have more freedom when they learn online. They can use the Internet to look for courses, combing their university or even the entire world for programmes, classes, and instructors who meet their requirements. They can enrol and register, search for books, read articles, listen to lectures, complete homework assignments, confer with their professors, and receive their final grades all online after they've discovered the right course. They can meet in virtual classrooms, where they can meet students from all over the world and form bonds and friendships that are impossible to form in traditional classes, which are normally limited to students from a specific geographic area.
