With so many distance education technologies, it’s easy to feel overwhelmed and confused. But learning about the variety of distance education technologies, isn’t as difficult as it may seem. They can be quite easily divided into four general categories: Print, Audio, Video and Computer. Distance education technologies are based on one, or some combination of these four categories —

1. Print – includes 1) correspondence study which is developed as print packages, as well as 2) any print materials that are component parts of other technology meetings, programs, or courses, i.e. brochures, study guides, handouts, or faxes.
2. Audio – consists of 1) inexpensive and easy to use audioconferencing, which can be used as a stand-alone technology point-to-point or with multiple sites; 2) it can also be incorporated into programs and courses that use other technologies. Also includes voice mail, an important way for faculty to meet with students and to provide feedback.
3. Video – comprised of a variety of technologies like 1) telecourses, which are pre-produced television programs on videotape, usually accompanied by a study guide and distributed via broadcast or cable channels. Telecourses can be viewed in real time, or downloaded, taped, and viewed by learners at a later time; 2) videotapes designed as component parts of programs or courses; 3) one-way live satellite videoconferencing that may include two-way audio for interaction; and 4) interactive video, where instructors and students can both see, hear, and interact with each other. Other technologies and media can be integrated into this system, providing the capability of a rich learning environment.
4. Computer – includes 1) self-paced learning packages which can be purchased by an individual or distributed over a network; 2) webconferencing which uses a Web browser, software, and a phone line to provide voice and graphics interaction among participants at their desktops. Webconferencing also includes a wide variety of tools for interaction, i.e. Powerpoint slide feature, white board, polling, chat, and desktop sharing; 3) the rich resources of the Internet and World Wide Web (WWW), which provides for email, sending attachments, and accessing audio and video; 4) group software which provides for discussion, chat, and document markup and editing; 5) Learning Management Systems (LMS) for managing courses and programs; and 6) CD-ROM and DVD which are computer storage media.
