The Internet has allowed people to communicate using computers, and as a result people have become more computer savvy. Just ten years ago, hardly anyone owned a personal computer, but now people of all ages use them nearly every day. Businesses also use computers for training purposes. I need to have a computer with the classes I am taking, as they usually rely on some computer use. One tourism class required me to use an online program called WebCT to take quizzes, and I have used email to contact professors and teaching assistants.
Many universities now offer courses, and often complete degrees, online.
There is no typical online student. Many are parents or people employed full time who wish to continue their education but cannot attend classes on campus. Some may be handicapped or older. Continuing education programs are offered in many schools, but course offerings can be limited. I am eligible to take continuing education classes, but classes for my major are not offered at night.
